If someone is interested in a simple and straightforward implementation of I2C on MSP430 with the USI module (the simpler serial module found on cheap low-end chips), I wrote a library a couple of years back, because I couldn't find anything I'd be happy with: https://github.com/jwr/msp430_usi_i2c https://github.com/jwr/msp430_usi_i2c The code is also fully interrupt-driven, which is important for low-power applications.
