PWM with PIC16F84A? | All About Circuits

BobTPH. Joined Jun 5, 2013. 8,265. Mar 14, 2014. #5. The timer on the PIC16F84A does not have a controllable duty cycle. Use a PIC with a PWM module, such as the 16F628. If you must use that PIC, you will have to control the on and off time separately by software, using either the timer or a program delay loop. Bob.
