I2C connectme


I have a module connect ME9210 and use NET-OS 7.4, and I need to make a comunicaion I2C. I use NAI2CInit and don’t has problem, but when I use NAI2COperation has problem and the function return equal a 1. What could cause this problem?

Check your GPIO.h to make sure that you have the pins free for I2C. This often happens if the pins are multiplexed for GPIO rather than I2C.
