  Hi Team, How does the watchdog work on the Monarco Hat? Is it automated or something we have to enable? Cheers Mike

  Hi Scoobsalamander, glad I could help. You are right, I didn't take to count the timing. Good luck with your project! Cheers, Tomas

  Hi Peter, thank you for reporting this and also sorry for difficulties. They made some major changes between version 5 and 6 of ArduinoJson library. I upgraded the Arduino sketch - see attached one. It can be compiled now however I don't have any ESP8266 around so didn't make any further tests. Let me know about your progress.

  An update to the above. I'm now very sure I had a bad batch of sensors, it turns out I'm not alone. Over people have seen the same thing having bought sensors from certain websites. Be careful when buying 1-Wire sensors as it seems there are cheaper, not so reliable ones flooding the market. Cheers Mike

  Hi Chris, thank you for reaching out. Yes, it is possible to interface with SX1509 via I2C using REXYGEN. However, it will require a bit of hand-coding. Have a look at function block called REXLANG and its function "OpenI2C" - https://www.rexygen.com/doc/PDF/ENGLISH/BRef_ENG.pdf#page=439 There are also some examples on I2C communication available - "0502 Generic I2C Communication" folder in Examples library (which is part of REXYGEN Studio) - these might help you to see how to implement the I2C communication according to your needs. Let us know about your progress. Regards, Tomas

  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 Richard, there are various "simplifications", using various offsets to distinguish between the four tables of data. For Holding registers, the most typical is offset of 40000, but as you already noticed, this is no standard. Best regards, Jaroslav

  @petrch Glad I could help Our developers already implemented the new functionality. Starting from new REXYGEN release it will behave as you expected - that Group itself will have also _Trigger flag. Good luck with your project. Regards, Tomas
