I am using the Capture from the CCP module of 16f877A to generate the RPM meter for the engine. The crankshaft has the teeth 28 or 32. Generally one of which is missing(so we get the pulse with double width) which marks the origin or reference, the rotation and hence the rpm.
I need to count 600rpm to 7000rpm, because the range is quite large I am not able to get the accurate result. Even with the steady input, the output keeps changing in a range of 10-20uS because of which the result is not accurate. Can anyone suggest how to achieve high accuracy while using the Capture module?
