Chapter 12
SPI Communication
Abstract
This chapter covers the popular Serial Peripheral Interface (SPI) for microcontroller communication. One master device controls bidirectional communication with one or more slave devices on the SPI bus, with a chip select line for each device to choose the device. This chapter explains how SPI works, describes the special function registers (SFRs) that control the SPI peripherals, and provides sample code for interfacing with a static RAM chip and an accelerometer/magnetometer at speeds of 10 Mbit/s.
