This chapter explains how to use interrupts in C programs for microcontrollers. Included is a full description of how the hardware and compiler deal with interrupts along with the responsibilities of the programmer. The different kinds of interrupts are described, with examples.
The reader will learn about when to use interrupts and interrupt timing issues, including interrupt latency. The variations between PIC® families in interrupt handing are described in detail. Programmers are taught how to deal with data accessed from inside and outside interrupt service routines (ISRs).
Examples and exercises are for the popular PIC® microcontroller manufactured by Microchip.
