A requirement for a work item is to monitor the frequency of a certain gpio input square wave! Popular speaking is a most simple oscilloscope to measure the frequency of the square wave! But just the frequency of the square wave! The frequency range is 0~200hz, and the frequency square wave is not always 200HZ, most of the time it may have been 0 or a lower frequency square wave! At the same time to take into account that the square wave may have been
