I try to wrap my head around a small project that involves reading / writing multiple I2C devices (display, sensors) on an Arduino Mega AT2560 with FreeRTOS. While I easily can set up my tasks and talk to the console / serial interface I don't seem to find an easy way to get the I2C comms up and running. I know that there may be some timing and interrupt issues around - but 2 days of extensive search on Google did not come up with a valid solution or application template. I certainly could get my scope out to check for any issues or rewrite IO libraries, but this would not be worth it at this point in time. Have you experienced the same problem? Can you point me to something that worked for you - like a 'hello world' for I2C on FreeRTOS for AVR/Arduino? BTW SPI seems to be covered a bit broader... PS: I use both the Arduino IDE and Deviot Thx.
