RPi.GPIO python module for Pine A64/A64+

Sorry...  

... you will need to either code for an internal pull-up,  or use an external pull-up resistor.

How are you providing '1' or '0' to the pin(3)  GPIO02 ?

Here is the code I use for my test push_button() :

I'm using BCM numbering  pin(35)   GPIO19

Code:

import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
p_switch = 19
GPIO.setup(p_switch, GPIO.IN, pull_up_down=GPIO.PUD_UP)


def push_button():
   if GPIO.input(p_switch):
       return False
   else:
       return True

This code works and is tested using debian image, and RPi.GPIO-Pine64 from github

With the pin open (internal pull-up as coded) push_button() returns False... else if the pin is grounded, push_button() returns True.


PS, you'll notice the push_button() is coded back-wards... because I want the push_button() to be a positive thing if pressed, but, if pressed its actually grounding the pin with the pull-up on it...
