Motor Control using Pulse-Width Modulation (PWM)


In this program, a jumper on Port B directly selects the PWM output. PWM output is only present if a jumper to ground is present on one of the least significant 3 bits of port B.



The program demonstrates the use of control registers to effect PWM operation.  One thing to notice is the fact that the program waits for a change on the input pins before selecting a new pulse-width duty cycle and reloading CCPR1.

Schmitt trigger for cleaning up noisy or slow-rising digital signals

  A Schmitt trigger is a circuit that converts an analog input signal into a digital output signal with hysteresis. It's characterised b...
