 determine square wave width... Hello, I'm new so please bear with me. I'm hoping to be able to use a PIC to determine the rising & falling edge of a square wave - If I have that info I can then determine the width of the pulse. I have a vague idea of how it can be done & only limited PIC programming experience (I was able to write a program & flash my PIC (16f84??) to get some LEDs to light up & blink)  Any help, comments, pics, etc. would be greatly appreciated! (what pins to use, can I hook up my signal directly to the pic (which pic, which inputs) or do I need some logic gates in between...???) Thanks, Jeff. | |

| The 16F84 is a somewhat simple PIC, the cheaper and better 16F628A has a CCP module and one of its modes can be used for pulse width measurement. | |
