Reading pulse widths

[armondo522]

I am trying to take measurements of the folling waveform coming in at 400Hz and want to sync an output to the wider of the 2 pulses. I am using a 18F458 proto board. any ideas on how this can be accomplished

the first pulse is 2.08 ms the second 1.96 ms with 460 us between them at a 400 hz rate.

Thanks

The CCP module can be used (in Capture mode) to do this.

See this CCS example file:
c:\program files\picc\examples\ex_ccpmp.c

Here's a CCS example file with another method:
