Using a very basic RPM sensor can I measure RPM in pixhawk ? The rpm sensor works digitally ( high and low states ) , can I use pixhawk Aux pins to read the pulses and use a counter to increment ?
Searched on the google forums and found that Lorenz suggested that can be done using the pwm_input.cpp in the drives. (https://github.com/PX4/Firmware/blob/master/src/drivers/pwm_input/pwm_input.cpp). But just cant figure out which pins and how to move forward
Any help would be grateful
