[C]de, one of our forum members, successfully managed to connect to an I2C port expander using I2C. His main goal was to connect to a 2*16 LCD and hence was in need of more I/O pins. He used the MSP430′s built in USI port to emulate I2C signals to a TI PCF8574 expander. He re-purposed [J]oby’s SPI Ninja command processing code for I2C.
