Is there supposed to be a voltage on the signal wire of the ADC port?
I've installed a SF02 on my plane and it works perfectly if I monitor the output analogue voltage. However, I'm getting nonsensical values on the pixhawk when viewing the range on "sonarrange".
I understood that the ADC is for reading data, yet I'm getting a signal, which of course clashes with the SF02's output.
Can anyone confirm that they have a voltage on their signal pin of the ADC port?
