Hi there,
I have an arduino which i am using as an I2C slave for the uVGAIII because it is faster than Serial. Using the uVGAIII as a master, i can easily send information to the arduino, but i cannot seem to send data back.
using the I2C_Read() command it returns 0 when the arduino is on and sending, if i put the arduino into reset the output from I2C_Read() returns 255. i can only get those two number despite sending an incrementing value from the arduino using Wire.write(x); (where x is an incrementing variable)
Am i using the I2C library on the uVGAIII wrong?
any help would be great thanks!
