roryhand 0:e89d7a0bfa3b 2 // 24/03/2018 update - I appear to be able to address the device and write something, as I am getting an ACK returned from the i2c write() function.
roryhand 0:e89d7a0bfa3b 3 //however if i use the write function with 4 arguments (as opposed to just 1 argument) then it doesnt work
roryhand 0:e89d7a0bfa3b 4 //only works with the 1 argument version!!!
