GPIO control does not work on Pi Zero 1 or 2 😣 #2

Hi,

Thanks for library! 😊 I've used it in a Volumio plugin. It's been tested on a Pi 5 and Pi 4 and setting GPIO works fine. However, on my Pi Zero 2 and Pi Zero, setting GPIO doesn't seem to do anything. 

gpiox.set_gpio(OUTPUT_PIN, 0);

What could be the issue?

Hello, that's very interesting. Unfortunately I don't have a Pi Zero 2 or Pi Zero to test. But I'll order one to test. The gpiox library uses the official character interface from Linux. The Pi Zero 2 and Pi Zero have a different CPU. It may be that this interface is not implemented for the Pi Zero 2 and Pi Zero. But I can't tell you that until I've tested it. Can you also tell me which OS and node.js version you are using the library on? Derya

Yes, I think you're right about the interface as the chips are different.

Here are the details: ☺

Thanks
