gounthar Posted April 10, 2020 Posted April 10, 2020 Armbianmonitor: http://ix.io/2htA Hi team, I am trying to get a voltage drop (3.3V to about 0V) detected on a GPIO pin on my OrangePi Zero running Armbian buster 20.02.1 with Linux 5.4.31-sunxi. I have another OrangePi Zero on which I have already managed to install I2C OLED screen, and the i2cdetect was working, and so on... For this one, I got a problem with the gpio group not existing. As I tried to install OPi.GPIO, I got usermod: group 'gpio' does not exist It's an Armbian version that I downloaded yesterday, and upgraded today with armbian-config. So... What did I do the wrong way? Thanks.

Why don't you use well known lib like : https://github.com/duxingkei33/orangepi_PC_gpio_pyH3 I think there is also a fork of it for specific OPiZero, which will avoid tweaking the mapping.h for the pins. 1
gounthar Posted April 10, 2020 Author Posted April 10, 2020 If there is one better suited library for the Zero, I will gladly use it. Thanks.
