I2C is a two-wire, bidirectional serial bus that provides a simple, efficient method of data
exchange, minimizing the interconnection between devices. This bus is suitable for
applications requiring occasional communications over a short distance between many
devices. The flexible I2C standard allows additional devices to be connected to the bus
for expansion and system development.
