Driver: 8255 Description: generic 8255 support Devices: [standard] 8255 (8255) Author: ds Status: works Updated: Fri, 7 Jun 2002 12:56:45 -0700 The classic in digital I/O. The 8255 appears in Comedi as a single digital I/O subdevice with 24 channels. The channel 0 corresponds to the 8255's port A, bit 0; channel 23 corresponds to port C, bit 7. Direction configuration is done in blocks, with channels 0-7, 8-15, 16-19, and 20-23 making up the 4 blocks. The only 8255 mode supported is mode 0. You should enable compilation this driver if you plan to use a board that has an 8255 chip. For multifunction boards, the main driver will configure the 8255 subdevice automatically. This driver also works independently with ISA and PCI cards that directly map the 8255 registers to I/O ports, including cards with multiple 8255 chips. To configure the driver for such a card, the option list should be a list of the I/O port bases for each of the 8255 chips. For example, comedi_config /dev/comedi0 8255 0x200,0x204,0x208,0x20c Note that most PCI 8255 boards do NOT work with this driver, and need a separate driver as a wrapper. For those that do work, the I/O port base address can be found in the output of 'lspci -v'.

Driver: addi_apci_1032 Description: ADDI-DATA APCI-1032 Digital Input Board Author: ADDI-DATA GmbH , H Hartley Sweeten Status: untested Devices: [ADDI-DATA] APCI-1032 (addi_apci_1032) Configuration options: None; devices are configured automatically. This driver models the APCI-1032 as a 32-channel, digital input subdevice plus an additional digital input subdevice to handle change-of-state (COS) interrupts (if an interrupt handler can be set up successfully). The COS subdevice supports comedi asynchronous read commands. Change-Of-State (COS) interrupt configuration: Channels 0 to 15 are interruptible. These channels can be configured to generate interrupts based on AND/OR logic for the desired channels. OR logic: - reacts to rising or falling edges - interrupt is generated when any enabled channel meets the desired interrupt condition AND logic: - reacts to changes in level of the selected inputs - interrupt is generated when all enabled channels meet the desired interrupt condition - after an interrupt, a change in level must occur on the selected inputs to release the IRQ logic The COS subdevice must be configured before setting up a comedi asynchronous command: data[0] : INSN_CONFIG_DIGITAL_TRIG data[1] : trigger number (= 0) data[2] : configuration operation: - COMEDI_DIGITAL_TRIG_DISABLE = no interrupts - COMEDI_DIGITAL_TRIG_ENABLE_EDGES = OR (edge) interrupts - COMEDI_DIGITAL_TRIG_ENABLE_LEVELS = AND (level) interrupts data[3] : left-shift for data[4] and data[5] data[4] : rising-edge/high level channels data[5] : falling-edge/low level channels Driver: addi_apci_1564 Description: ADDI-DATA APCI-1564 Digital I/O board Devices: [ADDI-DATA] APCI-1564 (addi_apci_1564) Author: H Hartley Sweeten Updated: Thu, 02 Jun 2016 13:12:46 -0700 Status: untested Configuration Options: not applicable, uses comedi PCI auto config This board has the following features: - 32 optically isolated digital inputs (24V), 16 of which can generate change-of-state (COS) interrupts (channels 4 to 19) - 32 optically isolated digital outputs (10V to 36V) - 1 8-bit watchdog for resetting the outputs - 1 12-bit timer - 3 32-bit counters - 2 diagnostic inputs The COS, timer, and counter subdevices all use the dev->read_subdev to return the interrupt status. The sample data is updated and returned when any of these subdevices generate an interrupt. The sample data format is: Bit Description ----- ------------------------------------------ 31 COS interrupt 30 timer interrupt 29 counter 2 interrupt 28 counter 1 interrupt 27 counter 0 interrupt 26:20 not used 19:4 COS digital input state (channels 19 to 4) 3:0 not used The COS interrupts must be configured using an INSN_CONFIG_DIGITAL_TRIG instruction before they can be enabled by an async command. The COS interrupts will stay active until canceled. The timer subdevice does not use an async command. All control is handled by the (*insn_config). FIXME: The format of the ADDI_TCW_TIMEBASE_REG is not descibed in the datasheet I have. The INSN_CONFIG_SET_CLOCK_SRC currently just writes the raw data[1] to this register along with the raw data[2] value to the ADDI_TCW_RELOAD_REG. If anyone tests this and can determine the actual timebase/reload operation please let me know. The counter subdevice also does not use an async command. All control is handled by the (*insn_config). FIXME: The operation of the counters is not really described in the datasheet I have. The (*insn_config) needs more work.

Each subdevice has a maximum of 32 channels. PCI-7230 - 2 subdevices: 0 - 16 input, 1 - 16 output PCI-7233 - 1 subdevice: 0 - 32 input PCI-7234 - 1 subdevice: 0 - 32 output PCI-7432 - 2 subdevices: 0 - 32 input, 1 - 32 output PCI-7433 - 2 subdevices: 0 - 32 input, 1 - 32 input PCI-7434 - 2 subdevices: 0 - 32 output, 1 - 32 output The PCI-7230, PCI-7432 and PCI-7433 boards also support external interrupt signals on digital input channels 0 and 1. The PCI-7233 has dual-interrupt sources for change-of-state (COS) on any 16 digital input channels of LSB and for COS on any 16 digital input lines of MSB. Interrupts are not currently supported by this driver.

AI subdevice supports cmd and insn interface, other subdevices support only insn interface. For AI: - If cmd->scan_begin_src=TRIG_EXT then trigger input is TGIN (pin 46). - If cmd->convert_src=TRIG_EXT then trigger input is EXTTRG (pin 44). - If cmd->start_src/stop_src=TRIG_EXT then trigger input is TGIN (pin 46). - It is not necessary to have cmd.scan_end_arg=cmd.chanlist_len but cmd.scan_end_arg modulo cmd.chanlist_len must by 0. - If return value of cmdtest is 5 then you've bad channel list (it isn't possible mixture S.E. and DIFF inputs or bipolar and unipolar ranges). There are some hardware limitations: a) You cann't use mixture of unipolar/bipoar ranges or differencial/single ended inputs. b) DMA transfers must have the length aligned to two samples (32 bit), so there is some problems if cmd->chanlist_len is odd. This driver tries bypass this with adding one sample to the end of the every scan and discard it on output but this can't be used if cmd->scan_begin_src=TRIG_FOLLOW and is used flag CMDF_WAKE_EOS, then driver switch to interrupt driven mode with interrupt after every sample. c) If isn't used DMA then you can use only mode where cmd->scan_begin_src=TRIG_FOLLOW.

AI subdevice supports cmd and insn interface, other subdevices support only insn interface. The PCI-1710 and PCI-1710HG have the same PCI device ID, so the driver cannot distinguish between them, as would be normal for a PCI driver. Driver: adv_pci1720 Description: 4-channel Isolated D/A Output board Devices: [Advantech] PCI-7120U (adv_pci1720) Author: H Hartley Sweeten Updated: Fri, 29 Oct 2015 17:19:35 -0700 Status: untested Configuration options: not applicable, uses PCI auto config The PCI-1720 has 4 isolated 12-bit analog output channels with multiple output ranges. It also has a BoardID switch to allow differentiating multiple boards in the system. The analog outputs can operate in two modes, immediate and synchronized. This driver currently does not support the synchronized output mode. Jumpers JP1 to JP4 are used to set the current sink ranges for each analog output channel. In order to use the current sink ranges, the unipolar 5V range must be used. The voltage output and sink output for each channel is available on the connector as separate pins. Jumper JP5 controls the "hot" reset state of the analog outputs. Depending on its setting, the analog outputs will either keep the last settings and output values or reset to the default state after a "hot" reset. The default state for all channels is uniploar 5V range and all the output values are 0V. To allow this feature to work, the analog outputs are not "reset" when the driver attaches. Driver: adv_pci1723 Description: Advantech PCI-1723 Author: yonggang , Ian Abbott Devices: [Advantech] PCI-1723 (adv_pci1723) Updated: Mon, 14 Apr 2008 15:12:56 +0100 Status: works Configuration Options: not applicable, uses comedi PCI auto config Subdevice 0 is 8-channel AO, 16-bit, range +/- 10 V. Subdevice 1 is 16-channel DIO. The channels are configurable as input or output in 2 groups (0 to 7, 8 to 15). Configuring any channel implicitly configures all channels in the same group. TODO: 1. Add the two milliamp ranges to the AO subdevice (0 to 20 mA, 4 to 20 mA). 2. Read the initial ranges and values of the AO subdevice at start-up instead of reinitializing them. 3. Implement calibration. Driver: adv_pci1724 Description: Advantech PCI-1724U Devices: [Advantech] PCI-1724U (adv_pci1724) Author: Frank Mori Hess Updated: 2013-02-09 Status: works Configuration Options: not applicable, uses comedi PCI auto config Subdevice 0 is the analog output. Subdevice 1 is the offset calibration for the analog output. Subdevice 2 is the gain calibration for the analog output. The calibration offset and gains have quite a large effect on the analog output, so it is possible to adjust the analog output to have an output range significantly different from the board's nominal output ranges. For a calibrated +/-10V range, the analog output's offset will be set somewhere near mid-range (0x2000) and its gain will be near maximum (0x3fff). There is really no difference between the board's documented 0-20mA versus 4-20mA output ranges. To pick one or the other is simply a matter of adjusting the offset and gain calibration until the board outputs in the desired range.

Each CTR is a 8254 chip providing 3 16-bit counter channels. Each channel is configured individually with INSN_CONFIG instructions. The specific type of configuration instruction is specified in data[0]. Some configuration instructions expect an additional parameter in data[1]; others return a value in data[1]. The following configuration instructions are supported: INSN_CONFIG_SET_COUNTER_MODE. Sets the counter channel's mode and BCD/binary setting specified in data[1]. INSN_CONFIG_8254_READ_STATUS. Reads the status register value for the counter channel into data[1]. INSN_CONFIG_SET_CLOCK_SRC. Sets the counter channel's clock source as specified in data[1] (this is a hardware-specific value). Not supported on PC214E. For the other boards, valid clock sources are 0 to 7 as follows: 0. CLK n, the counter channel's dedicated CLK input from the SK1 connector. (N.B. for other values, the counter channel's CLKn pin on the SK1 connector is an output!) 1. Internal 10 MHz clock. 2. Internal 1 MHz clock. 3. Internal 100 kHz clock. 4. Internal 10 kHz clock. 5. Internal 1 kHz clock. 6. OUT n-1, the output of counter channel n-1 (see note 1 below). 7. Ext Clock, the counter chip's dedicated Ext Clock input from the SK1 connector.

Reserved. 7. Reserved. INSN_CONFIG_GET_GATE_SRC. Returns the counter channel's current gate source in data[2]. Clock and gate interconnection notes: 1. Clock source OUT n-1 is the output of the preceding channel on the same counter subdevice if n > 0, or the output of channel 2 on the preceding counter subdevice (see note 3) if n = 0. 2. Gate source /OUT n-2 is the inverted output of channel 0 on the same counter subdevice if n = 2, or the inverted output of channel n+1 on the preceding counter subdevice (see note 3) if n < 2. 3. The counter subdevices are connected in a ring, so the highest counter subdevice precedes the lowest. The 'INTERRUPT' subdevice pretends to be a digital input subdevice. The digital inputs come from the interrupt status register. The number of channels matches the number of interrupt sources. The PC214E does not have an interrupt status register; see notes on 'INTERRUPT SOURCES' below.

When the interrupt status register value as a whole (actually, just the 6 least significant bits) goes from zero to non-zero, the board will generate an interrupt. No further interrupts will occur until the interrupt status register is cleared to zero. To clear a bit to zero in the interrupt status register, the corresponding interrupt source must be disabled in the interrupt source enable register (there is no separate interrupt clear register). The PC214E does not have an interrupt source enable register or an interrupt status register; its 'INTERRUPT' subdevice has a single channel and its interrupt source is selected by the position of jumper J5. COMMANDS The driver supports a read streaming acquisition command on the 'INTERRUPT' subdevice. The channel list selects the interrupt sources to be enabled. All channels will be sampled together (convert_src == TRIG_NOW). The scan begins a short time after the hardware interrupt occurs, subject to interrupt latencies (scan_begin_src == TRIG_EXT, scan_begin_arg == 0). The value read from the interrupt status register is packed into a short value, one bit per requested channel, in the order they appear in the channel list.

For internal clock sources, data[2] is set to the period in ns. INSN_CONFIG_SET_GATE_SRC. Sets the counter channel's gate source as specified in data[2] (this is a hardware-specific value). Not supported on PC214E. For the other boards, valid gate sources are 0 to 7 as follows: 0. VCC (internal +5V d.c.), i.e. gate permanently enabled. 1. GND (internal 0V d.c.), i.e. gate permanently disabled. 2. GAT n, the counter channel's dedicated GAT input from the SK1 connector. (N.B. for other values, the counter channel's GATn pin on the SK1 connector is an output!) 3. /OUT n-2, the inverted output of counter channel n-2 (see note 2 below). 4. Reserved. 5. Reserved. 6. Reserved. 7. Reserved. For the PCIe boards, gate sources in the range 0 to 31 are allowed; the following additional clock sources and clock sources 6 and 7 are (re)defined: 6. /GAT n, negated version of the counter channel's dedicated GAT input (negated version of gate source 2). 7. OUT n-2, the non-inverted output of counter channel n-2 (negated version of gate source 3). 8. "Pattern present" signal, HIGH while pattern present. 9. "Pattern occurred" latched signal, latches HIGH when pattern occurs. 10. "Pattern gone away" latched signal, latches LOW when pattern goes away after it occurred. 11. Negated "pattern present" signal, LOW while pattern present (negated version of gate source 8). 12. Negated "pattern occurred" latched signal, latches LOW when pattern occurs (negated version of gate source 9). 13. Negated "pattern gone away" latched signal, latches LOW when pattern goes away after it occurred (negated version of gate source 10). INSN_CONFIG_GET_GATE_SRC. Returns the counter channel's current gate source in data[2]. Clock and gate interconnection notes: 1. Clock source OUT n-1 is the output of the preceding channel on the same counter subdevice if n > 0, or the output of channel 2 on the preceding counter subdevice (see note 3) if n = 0. 2. Gate source /OUT n-2 is the inverted output of channel 0 on the same counter subdevice if n = 2, or the inverted output of channel n+1 on the preceding counter subdevice (see note 3) if n < 2. 3. The counter subdevices are connected in a ring, so the highest counter subdevice precedes the lowest. The 'TIMER' subdevice is a free-running 32-bit timer subdevice. The 'INTERRUPT' subdevice pretends to be a digital input subdevice. The digital inputs come from the interrupt status register. The number of channels matches the number of interrupt sources. The PC214E does not have an interrupt status register; see notes on 'INTERRUPT SOURCES' below. INTERRUPT SOURCES PCI215 PCIe215 PCIe236 ------------- ------------- ------------- Sources 6 6 6 0 PPI-X-C0 PPI-X-C0 PPI-X-C0 1 PPI-X-C3 PPI-X-C3 PPI-X-C3 2 PPI-Y-C0 PPI-Y-C0 unused 3 PPI-Y-C3 PPI-Y-C3 unused 4 CTR-Z1-OUT1 CTR-Z1-OUT1 CTR-Z1-OUT1 5 CTR-Z2-OUT1 CTR-Z2-OUT1 CTR-Z2-OUT1 PCI272 PCIe296 ------------- ------------- Sources 6 6 0 PPI-X-C0 PPI-X1-C0 1 PPI-X-C3 PPI-X1-C3 2 PPI-Y-C0 PPI-Y1-C0 3 PPI-Y-C3 PPI-Y1-C3 4 PPI-Z-C0 CTR-Z1-OUT1 5 PPI-Z-C3 CTR-Z2-OUT1 When an interrupt source is enabled in the interrupt source enable register, a rising edge on the source signal latches the corresponding bit to 1 in the interrupt status register. When the interrupt status register value as a whole (actually, just the 6 least significant bits) goes from zero to non-zero, the board will generate an interrupt. The interrupt will remain asserted until the interrupt status register is cleared to zero. To clear a bit to zero in the interrupt status register, the corresponding interrupt source must be disabled in the interrupt source enable register (there is no separate interrupt clear register). COMMANDS The driver supports a read streaming acquisition command on the 'INTERRUPT' subdevice. The channel list selects the interrupt sources to be enabled. All channels will be sampled together (convert_src == TRIG_NOW). The scan begins a short time after the hardware interrupt occurs, subject to interrupt latencies (scan_begin_src == TRIG_EXT, scan_begin_arg == 0). The value read from the interrupt status register is packed into a short value, one bit per requested channel, in the order they appear in the channel list.

Subdevice 1 pretends to be a digital input device, but it always returns 0 when read. However, if you run a command with scan_begin_src=TRIG_EXT, a rising edge on port C bit 3 acts as an external trigger, which can be used to wake up tasks. This is like the comedi_parport device, but the only way to physically disable the interrupt on the PC36AT is to remove the IRQ jumper. If no interrupt is connected, then subdevice 1 is unused. Driver: amplc_pc263 Description: Amplicon PC263 Author: Ian Abbott Devices: [Amplicon] PC263 (pc263) Updated: Fri, 12 Apr 2013 15:19:36 +0100 Status: works Configuration options: [0] - I/O port base address The board appears as one subdevice, with 16 digital outputs, each connected to a reed-relay. Relay contacts are closed when output is 1. The state of the outputs can be read. Driver: amplc_pci224 Description: Amplicon PCI224, PCI234 Author: Ian Abbott Devices: [Amplicon] PCI224 (amplc_pci224), PCI234 Updated: Thu, 31 Jul 2014 11:08:03 +0000 Status: works, but see caveats Supports: - ao_insn read/write - ao_do_cmd mode with the following sources: - start_src TRIG_INT TRIG_EXT - scan_begin_src TRIG_TIMER TRIG_EXT - convert_src TRIG_NOW - scan_end_src TRIG_COUNT - stop_src TRIG_COUNT TRIG_EXT TRIG_NONE The channel list must contain at least one channel with no repeated channels. The scan end count must equal the number of channels in the channel list. There is only one external trigger source so only one of start_src, scan_begin_src or stop_src may use TRIG_EXT. Configuration options: none Manual configuration of PCI cards is not supported; they are configured automatically. Output range selection - PCI224: Output ranges on PCI224 are partly software-selectable and partly hardware-selectable according to jumper LK1. All channels are set to the same range: - LK1 position 1-2 (factory default) corresponds to the following comedi ranges: 0: [-10V,+10V]; 1: [-5V,+5V]; 2: [-2.5V,+2.5V], 3: [-1.25V,+1.25V], 4: [0,+10V], 5: [0,+5V], 6: [0,+2.5V], 7: [0,+1.25V] - LK1 position 2-3 corresponds to the following Comedi ranges, using an external voltage reference: 0: [-Vext,+Vext], 1: [0,+Vext] Output range selection - PCI234: Output ranges on PCI234 are hardware-selectable according to jumper LK1 which affects all channels, and jumpers LK2, LK3, LK4 and LK5 which affect channels 0, 1, 2 and 3 individually. LK1 chooses between an internal 5V reference and an external voltage reference (Vext). LK2/3/4/5 choose (per channel) to double the reference or not according to the following table: LK1 position LK2/3/4/5 pos Comedi range ------------- ------------- -------------- 2-3 (factory) 1-2 (factory) 0: [-10V,+10V] 2-3 (factory) 2-3 1: [-5V,+5V] 1-2 1-2 (factory) 2: [-2*Vext,+2*Vext] 1-2 2-3 3: [-Vext,+Vext] Caveats: 1) All channels on the PCI224 share the same range. Any change to the range as a result of insn_write or a streaming command will affect the output voltages of all channels, including those not specified by the instruction or command. 2) For the analog output command, the first scan may be triggered falsely at the start of acquisition. This occurs when the DAC scan trigger source is switched from 'none' to 'timer' (scan_begin_src = TRIG_TIMER) or 'external' (scan_begin_src == TRIG_EXT) at the start of acquisition and the trigger source is at logic level 1 at the time of the switch. This is very likely for TRIG_TIMER. For TRIG_EXT, it depends on the state of the external line and whether the CR_INVERT flag has been set. The remaining scans are triggered correctly. Driver: amplc_pci230 Description: Amplicon PCI230, PCI260 Multifunction I/O boards Author: Allan Willcox , Steve D Sharples , Ian Abbott Updated: Mon, 01 Sep 2014 10:09:16 +0000 Devices: [Amplicon] PCI230 (amplc_pci230), PCI230+, PCI260, PCI260+ Status: works Configuration options: none Manual configuration of PCI cards is not supported; they are configured automatically. The PCI230+ and PCI260+ have the same PCI device IDs as the PCI230 and PCI260, but can be distinguished by the size of the PCI regions. A card will be configured as a "+" model if detected as such. Subdevices: PCI230(+) PCI260(+) --------- --------- Subdevices 3 1 0 AI AI 1 AO 2 DIO AI Subdevice: The AI subdevice has 16 single-ended channels or 8 differential channels. The PCI230 and PCI260 cards have 12-bit resolution. The PCI230+ and PCI260+ cards have 16-bit resolution. For differential mode, use inputs 2N and 2N+1 for channel N (e.g. use inputs 14 and 15 for channel 7). If the card is physically a PCI230 or PCI260 then it actually uses a "pseudo-differential" mode where the inputs are sampled a few microseconds apart. The PCI230+ and PCI260+ use true differential sampling. Another difference is that if the card is physically a PCI230 or PCI260, the inverting input is 2N, whereas for a PCI230+ or PCI260+ the inverting input is 2N+1. So if a PCI230 is physically replaced by a PCI230+ (or a PCI260 with a PCI260+) and differential mode is used, the differential inputs need to be physically swapped on the connector. The following input ranges are supported: 0 => [-10, +10] V 1 => [-5, +5] V 2 => [-2.5, +2.5] V 3 => [-1.25, +1.25] V 4 => [0, 10] V 5 => [0, 5] V 6 => [0, 2.5] V AI Commands: +=========+==============+===========+============+==========+ |start_src|scan_begin_src|convert_src|scan_end_src| stop_src | +=========+==============+===========+============+==========+ |TRIG_NOW | TRIG_FOLLOW |TRIG_TIMER | TRIG_COUNT |TRIG_NONE | |TRIG_INT | |TRIG_EXT(3)| |TRIG_COUNT| | | |TRIG_INT | | | | |--------------|-----------| | | | | TRIG_TIMER(1)|TRIG_TIMER | | | | | TRIG_EXT(2) | | | | | | TRIG_INT | | | | +---------+--------------+-----------+------------+----------+ Note 1: If AI command and AO command are used simultaneously, only one may have scan_begin_src == TRIG_TIMER. Note 2: For PCI230 and PCI230+, scan_begin_src == TRIG_EXT uses DIO channel 16 (pin 49) which will need to be configured as a digital input. For PCI260+, the EXTTRIG/EXTCONVCLK input (pin 17) is used instead. For PCI230, scan_begin_src == TRIG_EXT is not supported. The trigger is a rising edge on the input. Note 3: For convert_src == TRIG_EXT, the EXTTRIG/EXTCONVCLK input (pin 25 on PCI230(+), pin 17 on PCI260(+)) is used. The convert_arg value is interpreted as follows: convert_arg == (CR_EDGE | 0) => rising edge convert_arg == (CR_EDGE | CR_INVERT | 0) => falling edge convert_arg == 0 => falling edge (backwards compatibility) convert_arg == 1 => rising edge (backwards compatibility) All entries in the channel list must use the same analogue reference. If the analogue reference is not AREF_DIFF (not differential) each pair of channel numbers (0 and 1, 2 and 3, etc.) must use the same input range. The input ranges used in the sequence must be all bipolar (ranges 0 to 3) or all unipolar (ranges 4 to 6). The channel sequence must consist of 1 or more identical subsequences. Within the subsequence, channels must be in ascending order with no repeated channels. For example, the following sequences are valid: 0 1 2 3 (single valid subsequence), 0 2 3 5 0 2 3 5 (repeated valid subsequence), 1 1 1 1 (repeated valid subsequence). The following sequences are invalid: 0 3 2 1 (invalid subsequence), 0 2 3 5 0 2 3 (incompletely repeated subsequence). Some versions of the PCI230+ and PCI260+ have a bug that requires a subsequence longer than one entry long to include channel 0. AO Subdevice: The AO subdevice has 2 channels with 12-bit resolution. The following output ranges are supported: 0 => [0, 10] V 1 => [-10, +10] V AO Commands: +=========+==============+===========+============+==========+ |start_src|scan_begin_src|convert_src|scan_end_src| stop_src | +=========+==============+===========+============+==========+ |TRIG_INT | TRIG_TIMER(1)| TRIG_NOW | TRIG_COUNT |TRIG_NONE | | | TRIG_EXT(2) | | |TRIG_COUNT| | | TRIG_INT | | | | +---------+--------------+-----------+------------+----------+ Note 1: If AI command and AO command are used simultaneously, only one may have scan_begin_src == TRIG_TIMER. Note 2: scan_begin_src == TRIG_EXT is only supported if the card is configured as a PCI230+ and is only supported on later versions of the card. As a card configured as a PCI230+ is not guaranteed to support external triggering, please consider this support to be a bonus. It uses the EXTTRIG/ EXTCONVCLK input (PCI230+ pin 25). Triggering will be on the rising edge unless the CR_INVERT flag is set in scan_begin_arg. The channels in the channel sequence must be in ascending order with no repeats. All entries in the channel sequence must use the same output range. DIO Subdevice: The DIO subdevice is a 8255 chip providing 24 DIO channels. The DIO channels are configurable as inputs or outputs in four groups: Port A - channels 0 to 7 Port B - channels 8 to 15 Port CL - channels 16 to 19 Port CH - channels 20 to 23 Only mode 0 of the 8255 chip is supported. Bit 0 of port C (DIO channel 16) is also used as an external scan trigger input for AI commands on PCI230 and PCI230+, so would need to be configured as an input to use it for that purpose.

This board has 6 16-bit AO channels, and the usual 8255 DIO setup. (24 channels, configurable in banks of 8 and 4, etc.). This board does not support commands. The board has a peculiar way of specifying AO gain/range settings -- You have 1 jumper bank on the card, which either makes all 6 AO channels either 5 Volt unipolar, 5V bipolar, 10 Volt unipolar or 10V bipolar. Since there is absolutely _no_ way to tell in software how this jumper is set (well, at least according to the rather thin spec. from Measurement Computing that comes with the board), the driver assumes the jumper is at its factory default setting of +/-5V. Also of note is the fact that this board features another jumper, whose state is also completely invisible to software. It toggles two possible AO output modes on the board: - Update Mode: Writing to an AO channel instantaneously updates the actual signal output by the DAC on the board (this is the factory default). - Simultaneous XFER Mode: Writing to an AO channel has no effect until you read from any one of the AO channels. This is useful for loading all 6 AO values, and then reading from any one of the AO channels on the device to instantly update all 6 AO values in unison. Useful for some control apps, I would assume? If your jumper is in this setting, then you need to issue your comedi_data_write()s to load all the values you want, then issue one comedi_data_read() on any channel on the AO subdevice to initiate the simultaneous XFER. Configuration Options: not applicable, uses PCI auto config Driver: comedi_bond Description: A driver to 'bond' (merge) multiple subdevices from multiple devices together as one. Devices: Author: ds Updated: Mon, 10 Oct 00:18:25 -0500 Status: works This driver allows you to 'bond' (merge) multiple comedi subdevices (coming from possibly difference boards and/or drivers) together. For example, if you had a board with 2 different DIO subdevices, and another with 1 DIO subdevice, you could 'bond' them with this driver so that they look like one big fat DIO subdevice. This makes writing applications slightly easier as you don't have to worry about managing different subdevices in the application -- you just worry about indexing one linear array of channel id's. Right now only DIO subdevices are supported as that's the personal itch I am scratching with this driver. If you want to add support for AI and AO subdevs, go right on ahead and do so! Commands aren't supported -- although it would be cool if they were. Configuration Options: List of comedi-minors to bond. All subdevices of the same type within each minor will be concatenated together in the order given here.

Driver: das16m1 Description: CIO-DAS16/M1 Author: Frank Mori Hess Devices: [Measurement Computing] CIO-DAS16/M1 (das16m1) Status: works This driver supports a single board - the CIO-DAS16/M1. As far as I know, there are no other boards that have the same register layout. Even the CIO-DAS16/M1/16 is significantly different. I was _barely_ able to reach the full 1 MHz capability of this board, using a hard real-time interrupt (set the TRIG_RT flag in your struct comedi_cmd and use rtlinux or RTAI). The board can't do dma, so the bottleneck is pulling the data across the ISA bus. I timed the interrupt handler, and it took my computer ~470 microseconds to pull 512 samples from the board. So at 1 Mhz sampling rate, expect your CPU to be spending almost all of its time in the interrupt handler. This board has some unusual restrictions for its channel/gain list. If the list has 2 or more channels in it, then two conditions must be satisfied: (1) - even/odd channels must appear at even/odd indices in the list (2) - the list must have an even number of entries. Configuration options: [0] - base io address [1] - irq (optional, but you probably want it) irq can be omitted, although the cmd interface will not work without it. Driver: das1800 Description: Keithley Metrabyte DAS1800 (& compatibles) Author: Frank Mori Hess Devices: [Keithley Metrabyte] DAS-1701ST (das-1701st), DAS-1701ST-DA (das-1701st-da), DAS-1701/AO (das-1701ao), DAS-1702ST (das-1702st), DAS-1702ST-DA (das-1702st-da), DAS-1702HR (das-1702hr), DAS-1702HR-DA (das-1702hr-da), DAS-1702/AO (das-1702ao), DAS-1801ST (das-1801st), DAS-1801ST-DA (das-1801st-da), DAS-1801HC (das-1801hc), DAS-1801AO (das-1801ao), DAS-1802ST (das-1802st), DAS-1802ST-DA (das-1802st-da), DAS-1802HR (das-1802hr), DAS-1802HR-DA (das-1802hr-da), DAS-1802HC (das-1802hc), DAS-1802AO (das-1802ao) Status: works Configuration options: [0] - I/O port base address [1] - IRQ (optional, required for analog input cmd support) [2] - DMA0 (optional, requires irq) [3] - DMA1 (optional, requires irq and dma0) analog input cmd triggers supported: start_src TRIG_NOW command starts immediately TRIG_EXT command starts on external pin TGIN scan_begin_src TRIG_FOLLOW paced/external scans start immediately TRIG_TIMER burst scans start periodically TRIG_EXT burst scans start on external pin XPCLK scan_end_src TRIG_COUNT scan ends after last channel convert_src TRIG_TIMER paced/burst conversions are timed TRIG_EXT conversions on external pin XPCLK (requires scan_begin_src == TRIG_FOLLOW) stop_src TRIG_COUNT command stops after stop_arg scans TRIG_EXT command stops on external pin TGIN TRIG_NONE command runs until canceled If TRIG_EXT is used for both the start_src and stop_src, the first TGIN trigger starts the command, and the second trigger will stop it. If only one is TRIG_EXT, the first trigger will either stop or start the command. The external pin TGIN is normally set for negative edge triggering. It can be set to positive edge with the CR_INVERT flag. If TRIG_EXT is used for both the start_src and stop_src they must have the same polarity. Minimum conversion speed is limited to 64 microseconds (convert_arg <= 64000) for 'burst' scans. This limitation does not apply for 'paced' scans. The maximum conversion speed is limited by the board (convert_arg >= ai_speed). Maximum conversion speeds are not always achievable depending on the board setup (see user manual). NOTES: Only the DAS-1801ST has been tested by me. Unipolar and bipolar ranges cannot be mixed in the channel/gain list. The waveform analog output on the 'ao' cards is not supported. If you need it, send me (Frank Hess) an email.

All entries in the channel/gain list must use the same gain and be consecutive channels counting upwards in channel number (these are hardware limitations.) I've never tested the gain setting stuff since I only have a DAS-800 board with fixed gain. The cio-das802/16 does not have a fifo-empty status bit! Therefore only fifo-half-full transfers are possible with this card. cmd triggers supported: start_src: TRIG_NOW | TRIG_EXT scan_begin_src: TRIG_FOLLOW scan_end_src: TRIG_COUNT convert_src: TRIG_TIMER | TRIG_EXT stop_src: TRIG_NONE | TRIG_COUNT Driver: dmm32at Description: Diamond Systems Diamond-MM-32-AT Devices: [Diamond Systems] Diamond-MM-32-AT (dmm32at) Author: Perry J.

The interrupt subdevice (subdevice 3) is probably broken for all boards except maybe the 6514. This driver previously inverted the outputs on PCI-6513 through to PCI-6519 and on PXI-6513 through to PXI-6515. It no longer inverts outputs on those cards by default as it didn't make much sense. If you require the outputs to be inverted on those cards for legacy reasons, set the module parameter "legacy_invert_outputs=true" when loading the module, or set "ni_65xx.legacy_invert_outputs=true" on the kernel command line if the driver is built in to the kernel.

However, many of the isapnp id numbers are unknown. If your board is not recognized, please send the output of 'cat /proc/isapnp' (you may need to modprobe the isa-pnp module for /proc/isapnp to exist) so the id numbers for your board can be added to the driver. Otherwise, you can use the isapnptools package to configure your board. Use isapnp to configure the I/O base and IRQ for the board, and then pass the same values as parameters in comedi_config. A sample isapnp.conf file is included in the etc/ directory of Comedilib. Comedilib includes a utility to autocalibrate these boards. The boards seem to boot into a state where the all calibration DACs are at one extreme of their range, thus the default calibration is terrible. Calibration at boot is strongly encouraged. To use the extended digital I/O on some of the boards, enable the 8255 driver when configuring the Comedi source tree. External triggering is supported for some events. The channel index (scan_begin_arg, etc.) maps to PFI0 - PFI9. Some of the more esoteric triggering possibilities of these boards are not supported.

For the older Lab-PC+, not all input ranges and analog references will work, the available ranges/arefs will depend on how you have configured the jumpers on your board (see your owner's manual). Kernel-level ISA plug-and-play support for the lab-pc-1200 boards has not yet been added to the driver, mainly due to the fact that I don't know the device id numbers. If you have one of these boards, please file a bug report at http://comedi.org/ so I can get the necessary information from you. The 1200 series boards have onboard calibration dacs for correcting analog input/output offsets and gains. The proper settings for these caldacs are stored on the board's eeprom. To read the caldac values from the eeprom and store them into a file that can be then be used by comedilib, use the comedi_calibrate program. The Lab-pc+ has quirky chanlist requirements when scanning multiple channels. Multiple channel scan sequence must start at highest channel, then decrement down to channel 0. The rest of the cards can scan down like lab-pc+ or scan up from channel zero. Chanlists consisting of all one channel are also legal, and allow you to pace conversions in bursts.

Each channel is individually I/O configurable. The channel order is 0=A0, 1=A1, 2=A2, ... 8=B0, 16=C0, 24=D0. The driver only supports simple digital I/O; no handshaking is supported. DMA mostly works for the PCI-DIO32HS, but only in timed input mode. The PCI-DIO-32HS/PCI-6533 has a configurable external trigger. Setting scan_begin_arg to 0 or CR_EDGE triggers on the leading edge. Setting scan_begin_arg to CR_INVERT or (CR_EDGE | CR_INVERT) triggers on the trailing edge. This driver could be easily modified to support AT-MIO32HS and AT-MIO96.

See the notes for the ni_atmio.o driver for additional information about these boards. Autocalibration is supported on many of the devices, using the comedi_calibrate (or comedi_soft_calibrate for m-series) utility. M-Series boards do analog input and analog output calibration entirely in software. The software calibration corrects the analog input for offset, gain and nonlinearity. The analog outputs are corrected for offset and gain. See the comedilib documentation on comedi_get_softcal_converter() for more information. By default, the driver uses DMA to transfer analog input data to memory. When DMA is enabled, not all triggering features are supported. Digital I/O may not work on 673x. Note that the PCI-6143 is a simultaineous sampling device with 8 convertors. With this board all of the convertors perform one simultaineous sample during a scan interval. The period for a scan is used for the convert time in a Comedi cmd. The convert trigger source is normally set to TRIG_NOW by default. The RTSI trigger bus is supported on these cards on subdevice 10. See the comedilib documentation for details. Information (number of channels, bits, etc.) for some devices may be incorrect. Please check this and submit a bug if there are problems for your device. SCXI is probably broken for m-series boards. Bugs: - When DMA is enabled, COMEDI_EV_CONVERT does not work correctly.

If DMA/FIFO/INT are disabled then AI support only mode 0. PCL-818HD and PCL-818HG support 1kword FIFO. Driver support this FIFO but this code is untested. A word or two about DMA. Driver support DMA operations at two ways: 1) DMA uses two buffers and after one is filled then is generated INT and DMA restart with second buffer. With this mode I'm unable run more that 80Ksamples/secs without data dropouts on K6/233. 2) DMA uses one buffer and run in autoinit mode and the data are from DMA buffer moved on the fly with 2kHz interrupts from RTC. This mode is used if the interrupt 8 is available for allocation. If not, then first DMA mode is used. With this I can run at full speed one card (100ksamples/secs) or two cards with 60ksamples/secs each (more is problem on account of ISA limitations). To use this mode you must have compiled kernel with disabled "Enhanced Real Time Clock Support". Maybe you can have problems if you use xntpd or similar. If you've data dropouts with DMA mode 2 then: a) disable IDE DMA b) switch text mode console to fb.

This board doesn't support commands, and the only way to set its analog output range is to jumper the board. As such, comedi_data_write() ignores the range value specified. The board uses 16 consecutive I/O addresses starting at the I/O port base address. Each address corresponds to the LSB then MSB of a particular channel from 0-7. Note that the board is not ISA-PNP capable and thus needs the I/O port comedi_config parameter. Note that passing a nonzero value as the second config option will enable "simultaneous xfer" mode for this board, in which AO writes will not take effect until a subsequent read of any AO channel. This is so that one can speed up programming by preloading all AO registers with values before simultaneously setting them to take effect with one read command. Configuration Options: [0] - I/O port base address [1] - Do Simultaneous Xfer (see description) Driver: pcmmio Description: A driver for the PCM-MIO multifunction board Devices: [Winsystems] PCM-MIO (pcmmio) Author: Calin Culianu Updated: Wed, May 16 2007 16:21:10 -0500 Status: works A driver for the PCM-MIO multifunction board from Winsystems. This is a PC-104 based I/O board. It contains four subdevices: subdevice 0 - 16 channels of 16-bit AI subdevice 1 - 8 channels of 16-bit AO subdevice 2 - first 24 channels of the 48 channel of DIO (with edge-triggered interrupt support) subdevice 3 - last 24 channels of the 48 channel DIO (no interrupt support for this bank of channels) Some notes: Synchronous reads and writes are the only things implemented for analog input and output. The hardware itself can do streaming acquisition, etc. Asynchronous I/O for the DIO subdevices *is* implemented, however! They are basically edge-triggered interrupts for any configuration of the channels in subdevice 2. Also note that this interrupt support is untested. A few words about edge-detection IRQ support (commands on DIO): To use edge-detection IRQ support for the DIO subdevice, pass the IRQ of the board to the comedi_config command. The board IRQ is not jumpered but rather configured through software, so any IRQ from 1-15 is OK. Due to the genericity of the comedi API, you need to create a special comedi_command in order to use edge-triggered interrupts for DIO. Use comedi_commands with TRIG_NOW. Your callback will be called each time an edge is detected on the specified DIO line(s), and the data values will be two sample_t's, which should be concatenated to form one 32-bit unsigned int. This value is the mask of channels that had edges detected from your channel list. Note that the bits positions in the mask correspond to positions in your chanlist when you specified the command and *not* channel id's! To set the polarity of the edge-detection interrupts pass a nonzero value for either CR_RANGE or CR_AREF for edge-up polarity, or a zero value for both CR_RANGE and CR_AREF if you want edge-down polarity. Configuration Options: [0] - I/O port base address [1] - IRQ (optional -- for edge-detect interrupt support only, leave out if you don't need this feature) Driver: pcmuio Description: Winsystems PC-104 based 48/96-channel DIO boards. Devices: [Winsystems] PCM-UIO48A (pcmuio48), PCM-UIO96A (pcmuio96) Author: Calin Culianu Updated: Fri, 13 Jan 2006 12:01:01 -0500 Status: works A driver for the relatively straightforward-to-program PCM-UIO48A and PCM-UIO96A boards from Winsystems. These boards use either one or two (in the 96-DIO version) WS16C48 ASIC HighDensity I/O Chips (HDIO). This chip is interesting in that each I/O line is individually programmable for INPUT or OUTPUT (thus comedi_dio_config can be done on a per-channel basis). Also, each chip supports edge-triggered interrupts for the first 24 I/O lines. Of course, since the 96-channel version of the board has two ASICs, it can detect polarity changes on up to 48 I/O lines. Since this is essentially an (non-PnP) ISA board, I/O Address and IRQ selection are done through jumpers on the board. You need to pass that information to this driver as the first and second comedi_config option, respectively. Note that the 48-channel version uses 16 bytes of IO memory and the 96- channel version uses 32-bytes (in case you are worried about conflicts). The 48-channel board is split into two 24-channel comedi subdevices. The 96-channel board is split into 4 24-channel DIO subdevices. Note that IRQ support has been added, but it is untested. To use edge-detection IRQ support, pass the IRQs of both ASICS (for the 96 channel version) or just 1 ASIC (for 48-channel version). Then, use comedi_commands with TRIG_NOW. Your callback will be called each time an edge is triggered, and the data values will be two sample_t's, which should be concatenated to form one 32-bit unsigned int. This value is the mask of channels that had edges detected from your channel list. Note that the bits positions in the mask correspond to positions in your chanlist when you specified the command and *not* channel id's! To set the polarity of the edge-detection interrupts pass a nonzero value for either CR_RANGE or CR_AREF for edge-up polarity, or a zero value for both CR_RANGE and CR_AREF if you want edge-down polarity. In the 48-channel version: On subdev 0, the first 24 channels channels are edge-detect channels. In the 96-channel board you have the following channels that can do edge detection: subdev 0, channels 0-24 (first 24 channels of 1st ASIC) subdev 2, channels 0-24 (first 24 channels of 2nd ASIC) Configuration Options: [0] - I/O port base address [1] - IRQ (for first ASIC, or first 24 channels) [2] - IRQ (for second ASIC, pcmuio96 only - IRQ for chans 48-72 can be the same as first irq!)
