  Hello Martin, the main problem is that the pin modes are in reversed order. By setting pinmodes_A0_A7 to 0x66600000 you enabled A7, A6 and A5, not A0, A1 and A2 as you expect. The nonzero readings are then caused by picking up noise and other channels as mentioned by @sisktom2 Regards, Jaroslav

  Hi Stepan, I'd go for an external C program for this purpose. The main reason is efficiency and speed of execution. REXLANG is interpreted at runtime, therefore it is slower than native binary code. Either you can use the EPC block or REST API of REXYGEN. These are the 2 most straightforward methods when it comes to external programs. Kind regards, Jaroslav

  Hi James, There is no direct support in REXYGEN for reading the Raspberry Pi System Information. However I can imagine using Python script to read out the desired information (i.e. http://cagewebdev.com/raspberry-pi-showing-some-system-info-with-a-python-script/) and write it via REST API into REXYGEN algorithm. Have a look at example 0302-03_REST_API_Python_Bash_etc, which will help you with REXYGEN REST API integration. Hope the above is useful for you. Cheers, Tomas

  Hi Mike, unfortunately the REXYGEN runtime won't run on an ESP32, however you can integrate it with other REXYGEN enabled device using REST API and exchange data. Have a look at example "0302-11 ESP8266 REST API", which is originally meant for ESP8266 - I believe that the code will work also for ESP32 (with minor tweaks - don't have any ESP32 on my desk available for testing). Let us know about your progress. Regards, Tomas

  You are right, I am sorry for my mistake. According documentation https://www.rexcontrols.cz/media/2.50.5/doc/PDF/CZECH/BRef_CZ.pdf it seemed it was in basic installation. So it would be appropriate to modify my question: DO you consider embedding FMUCS to MODEL library in future? Thank you Stepan

  Hi, how about running Python code alongside REXYGEN and pushing the data to running task(s) via REST API of REXYGEN? This is shown in example project 0302-03 which is included in REXYGEN Studio. Both RS-232 and CAN bus are also an option, but in that case you'll only get raw data and you'll have to parse it yourself to get useful information. Hope this helps, let me know. Jaroslav

  Hello, thanks for another contribution! Why not use the MP block for starting the calibration procedure? Minor note: We always recommend keeping the block name for clarity and "readability" of the algorithm. I'd go for "REXLANG_MHZ16" in this case. Thanks again, Jaroslav

  @enovikoff Thank you, I'll see what can be done in this direction. Jaroslav
