Speaking of the battery management unit - is there any lib code anywhere (yet) for this part (U12)?
And also, I'm assuming previous i2master code isn't compatible with the SAMD21G - correct (or not)?
If we want to monitor a device that has an SMBUS I/F - (like a BQ2040, BQ2060, etc.) do we have to follow the procedure for the Sercom I/F since SMBUS isn't 100% compatible with I2C?:
