Low level sensors and chips library	1.4	GPLv2	OscadaLibs.db (SQL, GZip) > DAQ.tmplb_LowDevLib	en, uk, ru	Roman Savochenko Arcadiy Kisel (2017)	Library of templates to provide access to device's data of the low-level buses. Founded: Jul 2016 Initially created: in the old Wiki Used by: the smart house projects To Do: - to combine the 1W templates in one complex and append 1W to work through GPIO directly.

The user protocol devices library created to provide access to device's data of low-level buses, with protocols simple enough to implement into the User Protocol module or directly on the internal like to Java language.

The template's names and their parameters are available in languages: English, Ukrainian and Russian. Their source code wrote in the human-language independent mode with calls for the translations by the function tr() and the message's translation also allowed for English, Ukrainian and Russian.

For connection the library to a project of the OpenSCADA station you can obtain the database file as:

supplied with a ready and proper package of the Linux distribution like to "openscada-libdb-main", "openscada-LibDB.Main";
directly taken for most actual one from the subversion repository and converted to the DB SQLite file in the way:

$ wget http://oscada.org/svn/trunk/OpenSCADA/data/LibsDB/OscadaLibs.sql
$ sqlite3 -init OscadaLibs.sql OscadaLibs.db .exit

downloaded for the one attached here.

This obtained file next you can place into the project directory of the station and create the database object for the DB module "SQLite", registering the database file in the configuration.

For the DAQ-templates in generic you need to create a representing object of the device into the Logical controller module and to select the proper template from the templates library. Next, to correct configuration, follow to specific of the template into its individual description. The conception of accessing the data by a user protocol we can imagine like to Figure 1.

Fig.1. Conception of user accessing to services and device's data.

As you can see from Figure 1, interaction with devices carried out through some transport on which their physically based. Requests to the transport you can send:

Directly by OpenSCADA system API function of the transport object string messIO( string mess, real timeOut = 0 );, if the protocol specific part is very simple and you need only the data extract.
Wrapped data request req by function int messIO( XMLNodeObj req, string prt ); and for protocol prt, if the protocol part is complex enough and already presented into OpenSCADA.
Wrapped data request specific for user by function int messIO( XMLNodeObj req, "UserProtocol" ); and the user protocol implementation, if the protocol part is complex enough and not yet present into OpenSCADA. The user implements here itself of the protocol specific part into the module UserProtocol and the data specific part into the template for the Logical Level module or directly into controller's procedure on the internal language of the module JavaLikeCalc.

This latter method is currently developed to the possibility of forming a protocol code part directly in the same code of the template as a separate built-in function with call the requesting function of the first method, if there is no need for reuse, or even if such a need exists and it makes sense to create a complex template that can combine the role of the output protocol, through its connection to the user protocol module. And it will be completely stored in a single template library.

Working directly with the output transport of the string messIO(string mess, real timeOut = 0); function does not imply blocking the output transport outside this function call and, therefore, for complex protocols with response packets more than in one packet, which requires the "waiting" process, can not be used a shared transport, at which can be sent packets of different protocols or even one, but for different tasks (controller objects). Therefore, if you need to use shared transport, place the poll parameters in one controller object (task), or use the user protocol module to which this remark is irrelevant, since it performs such blocking at the time of the call of the processing procedure, as well as other modular protocols of OpenSCADA. To place a protocol implementation here you need to do and to follow for the shown demands:

be the copyright holder or the author of the code and distribute it under any free license, GPL preferred;
prepare and store into a separated DB file of SQLite, or as a text file, for: the parameters (IO) description, the procedure's code wrote and formed in some system way;
write a short description and instruction for connect a device by the protocol in way like to the other ones here;
write a direct request to the forum topic "OpenSCADA development" for placing the protocol here, include a proving of its ability to work from any OpenSCADA developer or a short demonstration video.

2. Create and start a logical controller object or use any presented one with the needed scheduling properties (FIFO-199).

3. Create a logical parameter and select the template for that, one for each sensor. Enable the parameter.

4. Into the tab "Template configuration" of the logical parameter object you need to set:

addr — to the address of the "BCM 2835" parameter like "DAQ.GPIO.io.pi"; tracing for the address changing is supported;
pin_cs — CS pin number where connected the chip selection pin of the sensor;
pin_sclk — SCLK pin number where connected the serial clock pin of the sensor;
pin_miso — MISO pin number where connected the master in slave out (data) pin of the sensor.

5. Result: The logical parameter will perform interaction and placing of the gathered data to the Temperature attributes.

14 GPIO\|I2C: 1602A(HD44780) (1602A)	1.0	GPLv2	*	en	Roman Savochenko

LCD Module 1602A, STN, BLUB, 16 Character x 2 Line, 5 x 8 Dots, by the direct (Raspberry PI BCM2835 GPIO) or I2C (PCF8574) wiring.
Conditions: Default planing policy but realtime one preferred.

Configuring and using

1. Create an output controller and an object of parameter in DAQ module "BCM 2835", by default it's "pi.pi" or create an output transport of the type "Serial", set address like to "i2c", one for each the I2C bus.

2. Create and start a logical controller object or use any presented one with the needed scheduling properties.

3. Create a logical parameter object and select the template for that, one for each sensor. Enable the parameter.

4. Into the tab "Template configuration" of the logical parameter object you need to set:

transport — to address of the "BCM 2835" parameter like to "DAQ.GPIO.io.pi" or to address of the transport into step 1; tracing for the address changing is supported;
addr — the I2C slave device's address [0...119];
RS, E, D4, D5, D6, D7 — numbers of the GPIO pins where connected the proper data ones of the sensor.

5. Result: The logical parameter object will perform interaction and setting lines' values to the display.
