Chapter 13
I2C Communication
Abstract
This chapter describes the PIC32’s inter-integrated circuit (I2C) communication peripherals. The PIC32 can be a master or a slave and communicate with one or more devices over a two-wire I2C bus. This chapter explains the I2C protocol, how the PIC32 special function registers (SFRs) are used to transmit and receive data, and provides sample code for the PIC32 to act as an I2C master, an I2C slave, and to communicate with an accelerometer and an OLED screen.
