I don't have hardware yet, so I can't try this out, but reading the datasheets I see an apparent incompatibility between the bq77PL900 and the MSP430 in the area of the I2C interface. The bq77PL900 says that it doesn't send ACKs, but the MSP430 appears to require them and reacts when it doesn't see one. Am I reading too much into this, or is it a real problem which requires a workaround? Does anyone have any proven code to share?
Thanks,
Scott
I've not used those 2 devices together but do not expect any problem.
The bq77PL900 will ACK its address, but does not ACK the general call address (00). "General call address" seems to have become "general code" in the datasheet page 38 description, although some other implication about optional features may have been intended. See page 39 for protocol figures. Sorry for the confusion.
The MSP430 group has several code examples available which are not specific to the bq77PL900. Please see 
or the product folder for your processor.
