Re: frequency counter

The basic idea for any frequency counter is to set a timer, wait till the input on a pin change, calculate the time taken and find the inverse.

There are lots of schematics on the net, use google.

A very crude design can be found here : **broken link removed**

Try searching for PIC frequency counter schematic for something that utilizes a miocrocontroller.
