Purpose:
The pedal board reads the ADCs for the throttle and brake pedals and broadcasts the data to the MCI.
...
The driver should send the slave address with a read byte (11001001), after which the MAX will begin sending AIN0-2 until the master transmits a STOP condition.
...
max11600_read_raw:
Send the slave address 11001001, read in three values in binary, discard the steering value, transmit STOP condition.
...
Calls max11600_read_raw, then converts the values to the value in mV. Look at Figure 12 on the datasheet to understand how to convert from binary to mV.
