V R Siddhartha Engineering College Autonomous and Affiliated to JNTUK, Kakinada Department of Information Technology I2C The I2C (Inter-IC) bus is a bi-directional two-wire serial bus that provides a communication link between integrated circuits (ICs). Phillips introduced the I2C bus 20 years ago for mass-produced items such as televisions, VCRs, and audio equipment. Today, I2C is the de-facto solution for embedded applications. 6/4/2019IOT by K.Durgacharan 6
