For the most part the i2c-3 seems to be working fine.
My Config.txt file...which doesn't have much in it. I have added the baudrate in the hope to slow things down as I seem to have some intermittent faults on loading registers. I commented out the SC16IS752 overlay install as I never got it to work on the rPi Zero.
