Hi all, I am using AT89C52 and I am writing C codes to program my chip. I wanna use the counter to count the number of pulses (around 1-2kHz) in a specific time, say 100ms. Could anyone give me some suggestions for writing the codes? Thank you very much! Dave
enable counter start trimer when timer times out stop timer disable counter read counter Erik
May I know can I disable the counter in an ISR (the ISR be called when timer overflow)? And how to read the values in a counter? Thx very much~
