RPi.GPIO python module for Pine A64/A64+
#39
You will need to provide an external pull-up resistor 4.7k to 3v3...

...that will give you '1' unless you ground the pin (on the pin side of the 4.7k resistor.

Or, you can define the input as having a pull-up and then the pull-up will be internal.


PS you can experiment with 'strong' or 'weak' pull-up resistors, anything from 1k to 10k, the higher the number, the weaker the pull-up.

PSS I too will experiment with pin(3) GPIO02 as input... on debian... will get back to you soon
