Chapter 19
Advanced Timing
Abstract
This chapter describes the peripherals associated with timers on most PIC® microcontrollers.
Pulse width modulation (PWM) is fully explained, with diagrams and C code examples. The capture peripheral found on most PIC® processors allows a timer value to be captured in response to an external event. The compare peripheral also on most PIC® processors triggers an event when the timer reaches a specific value. Both capture and compare are fully described with C examples.
The differences between the 24 bit opcode PIC® processors, and the other processors as it applies to the timer peripherals, are also explained.
Examples and exercises are for the popular PIC® microcontroller manufactured by Microchip.
