IIC, the Inter-Integrated Circuit, which is a simple, bi-directional, two-wire, synchronous serial bus designed by Philips Semiconductors in the early 1980s to primarily connect the overall circuit (ICS), IIC is a multi-directional control bus, that is to say a number of chips can be connected to the same bus structure, while each chip can be used as real-time data transmission control source. This way simplifies the signal transmission bus interface.
