PIC18F4520: PWM Motor Control

Pulse Width Modulation, or PWM, is a technique used to vary the average magnitude of a signal by changing its duty cycle (the proportion of time that a signal is active or "high"). For more information on the basics of PWM motor control click here.

Available Pins

The PIC18F4520 is capable of outputing a PWM (Pulse Width Modulation) signal on two separate channels: CCP1 and CCP2 (shown below). The red pins have the capability of outputing PWM, while the grey are usually committed to communication or power.
