I am building a demo with the MangOHGreen board and a HL7692 in the CF3 socket.
No problem so far. The Arduino sketch works with out problem also the communication from the Arduino is working.
I want to connect a 1.5inch OLED to the Arduino with I2C.
But when connecting anything on the I2C board (on both available pin locations for I2C). I know that the Leonardo I2C pinning is different than a standard Arduino but my I2C sketch is workings on a original Leonardo board.
When my sketch stripped to minimum the I2C still doesn’t work.
I have two MangOH Green boards, and both are not working.
Anybody experience with this?
