PWM operation steps Following steps are needed to setup the PWM module in PIC18F4550. Set the PWM Period Set PWM duty cycle Output pin configuration Prescalar value and timer configuration PWM Module configuration 1. Set the PWM Period The PWM period is set by writing the PR2 register. So the value can be calculated by using this formula.i.e,

PIC18 Simple PWM Setup Hi there, I'm new at working with PICs and am trying to setup a standard PWM on my PIC18F25K22, but getting no where. I'm following the steps outline in section 14.3.2 of the datasheet, and have gotten the following setup code. main just calls this code, then calls a function that sets a duty cycle, then sits in a while(1 ...
PIC PWM: Easy Pulse width Modulation on the PIC Micro.
https://www.best-microcontroller-projects.com/pwm-pic.html
PIC PWM : Pulse Width Modulation. PIC PWM for the PIC Microcontroller. This page shows you how to setup registers in PIC microcotnrollers to control the PWM module. Pulse width modulation or PWM is simply the creation of a digital signal that is turned on and off at a repeated rate (specific period) and with a varying mark to space ratio.

The microcontroller selected to this project is a PIC 18F1320 [ 3] with 8KBytes of flash memory and an ECCP unit. A smaller flash unit also exists (18F1220) but remember that those 8 KBytes of flash allow almost a second of PCM audio sampled at 8000Hz to be loaded into the PIC. Less memory equals less recording time.
