Detailed Description

Measures the pulse width of pushbutton switching using input capture and Timer2 This projects uses an external crystal for accuracy. CLOCK_CONFIG=PRIPLL_8MHzCrystal_40MHzFCY is defined in the MPLAB project. Remove this macro if you wish to use the internal oscillator. Typical crystal accuracy for through hole is +/-20 pmm, so for a 100000 us pulse width measurement this is +/- 2 us.
