SMBus in MSP430 Value Line

Other Parts Discussed in Thread: MSP430G2102

Hi,

We developed a smart battery standalone charger.

Now we want to add a slave ucontroller to the system.

The idea is read the battery parameters using I2C and display SoC, voltage, current, full charge, etc.

Is it possible to add a MSP430 Value Line (eg. MSP430G2102) to the smbus to monitor battery status?

Is there any sample code we could use?

Best regards,

Andre Fernandes

    In general, SMBUS is a lot like I2C, but it is not the same. A good reference on the differences is here: http://www.maximintegrated.com/app-notes/index.mvp/id/476

    One of the things I notice is the inability to program the 2xx series MSP devices to output a clock when idle. This may be able to be mitigated by making sure to issue a transaction on the bus often enough to avoid the slave timeout function.
