Generating PWM signals on GPIO pins of PIC Microcontroller

Generating PWM signals on GPIO pins of PIC Microcontroller

PWM signal generation is a vital tool in every embedded engineers arsenal, they come in very handy for lot of applications like controlling the position of servo motor, switching few power electronic ICs in converters/invertors and even for a simple LED brightness control. In PIC microcontrollers PWM signals can be generated using the Compare, Capture and PWM (CCP)
