Are you sampling the result every 5mS ?
i will sampling result every 100ms but the time it take to measure frequency shouldnt be more than 5 ms !( some times frequency is much lower than 50khz ! i dont need them !
if for example frequency = 10hz it at least take 100ms to measure !! but it shouldnt take that much time !
(i do not need to measure frequency lower than 50khz !
thank you for your help . best regards
