PWM signal

[Battalinoglu]

Hello everyone,

A newbie question,

I have a sensor that produces a PWM signal. What I need to do is calculating the width of the pulse with 16F877. If it is greater than some value pic will HIGH PORTx.x
Do i need to use a timer interrupt? I'll be glad if you could help me with the code.

Thanks mehmetOzdemir,

I am in a dilemma of using a low-pass filter and using timer interrupts.
Any suggestions?
