#144851 - upsd3354D GPIO input question |
I an using pin 3.2 as a digital input on my chip. The problem that I am having is, I have a dry NC contact on this input and when it goes from close to open I see the state change, but it never releases. The data sheet says to get the pin "input ready" the pin needs to be set to a one, which I am doing before I read the pin.
My question is how do it get the pin to correctly read the input? I have searched for info, but have not found anything yet. Thanks, Matt |
