This module goes through details about Finite State Machinesprovides software members with a high-level overview of a simple inter-board communication protocol (SPI), which is often used to communicate with peripherals.

Goals for this Module

After going through this module, I will be able to:

• Understand how Finite State Machines work
• Read a Finite State Machine diagram
• Draw a Finite State Machine diagram for a boardunderstand how communication over SPI works
• use SPI to communicate with a peripheral
