Print Page - GPIO access without root

Title: GPIO access without root
Post by: Pertinax on March 28, 2022, 08:24:16 PM

I am about to develop a GUI in Python to access GPIO, I2C, CAN bus on A20+Shield. I realize, that access to GPIO is only possible as root, which I dislike for an application
Is it possible to define a group my user belongs to and have this group be the owner of the necessary directories? If so, which do I have to set?

Thanks

Not sure about that one. But you can check how years ago we did some Python modules for other boards in the past:

https://pypi.org/project/pyA20Lime2/
https://pypi.org/project/pyA20/

I am not even sure if these modules work with latest Olimage images but probably can be of help.

There are posts on the net about how to access Linux gpio as non-root.

I'm reluctant to insult anyone by describing how to do web searches!!
