pic frequency counter using 16f877a


Posted on Feb 7, 2014

It uses the simpler method of direct frequency measurement which is easy to do but means that the number of digits displayed depends on the input frequency. If you want to display all digits all the time there is a technique called reciprocal counting- but this requires floating point (maybe fixed point) routines and would be difficult to implement with this hardware since it needsconstant time routinesto count accurately.
