Hi, im using a teensy 4.0 connected to a sensor that gives a digital output, it works fine with a short cable but with a longer one im getting around 0.15v pk2pk noise which seems to be triggering my interrupt routine.
ive done abit of searching but cant find any information as what the minimum voltage change the teensy regards as a change, does anyone know this or even better - how to modify this threshold?
many thanks in advance
andrew
