Hello,
I'm new to msp430 programming. I am attempting to make a frequency counter for a very low frequency range.
So, I have a square wave signal coming out of a schmitt trigger that has a frequency range of 0-150Hz with max 3.3V going into the msp430.
Is it possible to do this the following
Have a known faster clock signal run and count the rising edges in one period of the input signal.
Then unknown freq= known/count
Can someone point me in the right direction or show me an example code? I am trying to do this with Timer A and capture but I am not sure exactly how to.
