Frequency detector via micro-controller?
I have a square wave generated by a 555 multivibrator. I want to detect its frequency via ATMEL 89c51(preferable) or any other microcontroller. can anybody kindly give me some hints to make it happen or tell the steps to make it happen.
I know the basics of analog electronics a bit BUT new in the digital electronics & micro-controller field. kindly help me.
