I2C with REXDuino



  • Hi, is there any example how to use I2C with REXDuino? I followed all accessible documentation and codes both for master part and slave part of REXDuino, and spent a lot of time on a simple task, trying to set CNR value between 0-3.3 [V] , convert it to appropriate format in order to connect it to userSendV input of Arduino_UNO. The goal is to control DAC converter MCP4725 via I2C communication using REXDuino with Arduino Uno to make the converter's output OUT set to desired voltage level according the value written in CNR. Any help appreciated. Stepan



  • Me and my colleague finally implemented some functional solution. We make it public if anyone is interested. Many thanks to Ing. Tomáš Dočekal!
