I'm looking at using a voltage to frequency counter in an app, feeding the pulse train into an 16F877 to measure the frequency. I haven't played with the newer PICS with their fancy additional hardware. What is the maximum frequency I'm likely to be able to measure with a 20 MHz '877? Will it handle 100 kHz?
