	Regards, Jacek What is confusing you is the fact that you never see a number but always its digit representation. So you end up thinking that the number is the representation. - Andrej Bauer Any claims against me - based on whatever legal reason - resulting from the use of any code and/or ideas presented on this forum shall be excluded. #StayWithUkraine

NOTE: for low frequencies (long periods) You will get better accuracy when you measure PERIOD (i.e. time between pulses) and then calculate frequency f=1/Period
