I have 4 pulses to count. They range from one pulse every few seconds, to one source that will pulse about 10 times a second- so none are stunningly fast.
Best option? I've had luck using a gpio pin and python edge detection on a single pulse, but with multiple pulses (even on separate pins) I get too many false-positives.
Is there such thing as a 'raspberry pi-pulse-counting addon board'? Another microchip to count pulses that my pi can then just get the count from? Examples of a pi-only gpio solution with multiple pulses?
