The I2Cm User Module implements a master I2C device in firmware. The I2C bus is an industry standard, two-wire interface developed by Philips®. An I2C bus master may communicate with several slave devices using only two wires. The master initiates all communication on the I2C bus and supplies the clock for all slave devices. The I2Cm User Module supports speeds up to 100 kbps. No digital or analog user blocks are consumed with this module.
