Using CCP1 and CCP2 in capture mode with Timer1.

[Bruce]

You would probably get better results if you enable 1 capture at a time, stop timer1 before clearing it & entering CaptureLoop2.

Are you trying to measure the period or high-going pulse width?

Hi thanks for your reply

I am measuring the period of the incoming pulses.

I have to say I had not considered enabling one CCP at a time. Would I acheive this changing the CCPxCON statement? (x being 1 or 2). Such as CCP1CON = %00000000.

Thanks.

Yes. Enable 1. Wait for capture. Disable 1, Enable 2, wait for capture, etc. It's a good idea to stop Timer1 before clearing it also.

Many thanks Bruce for your advice.

I have done as you have suggested, including stopping Timer1 (T1CON = 0) before clearing, and all appears to be operating as it should. I am a happy chappie.....

Once again many thanks. Sorted.....
