Hi, could you clever people out there give me some advice on counting the
'length' of pulses.  The pulses come from a chopper wheel on a motor.
Eventially I will alter the speed of the motor (PWM duty cycle) depending on
the length of the pulse, but for now I just want to measure it.

Is there any specific hardware on the 16F877? Is this what the capture port
does?
How does it work? I have read the manual but do not really understand it. I
am using CCP1 to control the motor (PWM mode), can I use the other to
'capture' the length of pulse?

Thankyou all for your help so far, and hopefully in the future

Graham North
