Hi ,Martin Thank your for your suggest, I initially followed this method, but found that the dog could not be fed successfully. Our external microcontroller feeds the dog. The cpu just gives the microcontroller a trigger signal, but I tested that the microcontroller cannot detect the level change using this method you said So I used the script.
