Pulse-Width Modulation (PWM) Measurement with a PIC Microcontroller
A Microchip Technology PIC microcontroller can be an accurate solution for calculating the timing of a pulse-width modulation (PWM) signal due to its architecture. With this design, you can measure high and low pulse durations, as well as the period, all with the resolution of 1 µs for pulse durations from 10 to 65,535 µs for PWM signals with frequencies in the range of 7.63 Hz to 50 kHz.
