Been using the Frequency Measurement Library, it's great. Been using it to measure the speed and RPM on my car. Is there a way of measuring 0 frequency to show 0 speed or 0 RPM at all?Thanks.
Just as a heads up, if you are getting your signal from a hall effect sensor you should be able to read zero speed, but from what I have been looking up, most speed sensors are a much cheaper variable reluctance sensor. As I understand it, variable reluctance (VR) sensors do not do well at slow speeds. This code and my VR sensor off of a Borg-Warner T5, for a S-10, cannot go down to 0 rpm. I can only get to 10s or rpm. Hall effect sensor can take true zero speed measurements. Good luck.
