Hi All,
So I have a new project on my plate and the project manager wants to use "smart batteries" from the company RRC.
Looking through the specification the batteries seem to use the SM Bus to provide data to the control system (SM Bus seems close enough the i2c to make it almost compatible). The only thing I can see is that if the battery has a critical alarm it switches over to master mode and sends out a distress beacon every 10 seconds.
So my questions are
1) Does anyone have any experience with connecting up to SM Bus devices with Atmel AVR's
2) What would be the best way to handle the critical condition? What I thought of is a i2c switch to cut off the communication to the battery or use a seperate i2c bus just for the battery (I have 3 or 4 other i2c sensors in the same project). Using multiple i2c buses would mean using an atxmega part, which I'd like to avoid if I can.
Regards
Ian Dobson
