I have designed a new card with TCA6507 Led controller and using msp430f2272 micro controller does any one have c code for I2C communication code of LED Controller?
While this might no longer be useful to the original poster:

TI has a buried example code for the TCA6507. It is intended for a Stellaris mcu, but is abstract and commented enough to serve as very useful example code.
