This document is an overview of the use of the I2C master function set for MSP430 devices with the USCI module. These functions can be used by MSP430 master devices to ensure proper initialization of the USCI module and provide I2C transmit and receive functionality. A similar version with DMA support has also been included. The USCI I2C master function set only supports single-master transmitter/receiver mode using 7-bit device addressing.
Note: The USCI I2C master package includes a demonstration application that can be used on any MSP430 2xx device with the USCI module.
