Many Sensors use this serial communication protocol to transfer their data to microcontrollers or through this protocol different slave circuits are able to communication with master circuits. I2C bus supports multiple slave devices and multiple master devices. It is a very popular communication protocol used in embedded projects to interface I2C based sensors, digit displays, and communication modules.ĭevices that want to communicate with each connects through an I2C bus. It is a 2-wire serial communication protocol for short range data transfer applications. I2C means Inter-integrated circuit communication protocol.
