I am doing a project, AT80C59 microcontroller. I want to make a program for counting frequency of the pulses on port 1.2. it should do this in loop. Plz help me to write this code. also i want to write this code in bascom software only.

 

Gate the pulses into an internal counter for an accurate period of time. Perhaps 10 seconds. The accumulated count multiplied by 6 will equal the number of pulses in one minute.
