This application note describes how to communicate with the bq76940 family devices over I2C. The code is based on the TI MSP430G2553. The code shows how to write the CRC function which is used to verify the transaction integrity over the I2C and how to initialize the I2C engine of the G2553 and bq76940 registers as well as how to read binary data from the AFE registers and transfer the data to voltages.
