Hi…
The J2 PIN1 is the “Ve”. I think that pin gives 3.3v continuously, but in my card don´t work:
I have connected this pin (Ve) to a button to input signal in GPIO45.
I press the button and GPIO45 (mode pulldown) don´t detect signal. Everytime is 0 “low”.
If I connect the button to the PIN J3-PIN2 (3V3) , I press the button and GPIO45 detect “HIGH” (works OK).
Is necessary to program “Ve” PIN?
(I am working with IDE arduino)
Thanks
