Hi
I have an ds1307 in a 3.3v I2C bus, pulled with 4.7k resistors, N+2 returns 0s, when try with Arduino I have not problems.
With N+2 running, after many times disconnecting the I2C bus and reconnecting then reads begins, but when mod my code and compile again, the problem returns.
My firmware is 4.2.2.2
any idea?
