Do you have any ballpark numbers how much time does it take to read all 48 pins on an arduino uno for example?
Would it be suitable for a low latency device like a keyboard or midi controller?
Hi,
The reason you are having read problems is that the read I2C address needs to be the write I2C address plus 1.
So this line in readAll should be
81 Wire.requestFrom(deviceAddress + 1, 6);
Hope this helps.
