I have the need to measure the duration of short bursts of a square or sine wave signal coming into a PIC 16F88 at a constant frequency of 20KHz. The bursts last between one and 150 milliseconds and I need the time measurement to be accurate to about a half millisecond. I was thinking of using an interrupt-on-change on the input pin and saving the time of the first interrupt and subtract it from...

Has anyone successfully sent Fosc/4 to RA6 when using the internal RC oscillator at 8 MHz? I have tried a lot of combinations of Fosc and _CONFIG1 but so far, no output. I thought I did a pretty good job of reading the datasheet but still, no output; I must have missed something.

What is the best way with a PIC 16F88 to time short bursts of 20KHz on an input line? I expect the bursts to be any one of 64 discrete time durations, where the shortest duration is 1.5 ms and the maximum duration is 127.5 ms. The possible durations are evenly spaced, which means that each duration differs from the next shortest or longest duration by 2 ms. I only need to know which of the 64...
