Hi all,
I am using the 8031 timer1 in count mode to count the closures of a read switch. The frequency is 200 pulses per second. When i give the input from a pulse generator to my kit, the result is repeatetivly correct. But when i connect the read switch input, the result is not repeating. It varies between +/- 2Hz (10 pulses in 5 seconds).But the same reed switch if connected to a ICM 7217 based counter, the result is repeating. The problem with my 8031 kit,I persume is because of reed switch debounce. How do i introduse debouncing to the timer when it works in external count mode.
