CCP module on PIC16F877

[Wayne Siebrecht]

I would like to capture two separate variable duty cycle singals and I was wonding if there was a simple way to do it with the CCP module on the PIC16F877. Flipping the interrupts back an forth from rising to falling edge seams to be the way, but I can't seam get it right and it is very confusing. Is there a more elegent method. I haven't found a good example or anything even close for a guide using the CCP. Any ideas?

Have you looked at the CCS example file, EX_CCPMP.C ?
