Long story short. I2C is working fine between the Raspberry Pi and the Arduino. I am using the 16 bit write from the wiringPi library, which sends 3 bytes at a time including the register/address. This is sensor data and it doesn't make sense to send more than 3 bytes at a time, as if I had another …

It should be possible to transmit thousands of bytes per second, but I do advice to have 100 microseconds between the transmissions.

You didn't show the ControlByteCheck() function. Is something weird going on there ?
