GPIO in the opi PC

1st Official Post

    I noticed that the gpio is being used for a remote control projects so I am wondering if I could use it for temperature sensing with the DS18B20.

    In armbian I enable it by adding to /boot/armbianEnv.txt:

    Code
    overlays=w1-gpio
param_w1_pin=PD14

    If it is possible to use this sensor. How do I enable it?

    I have a orange pi PC

    Thanks for your help

    W1 is not enabled in kernel config yet. Additionally, LE also doesn't support DT overlays yet. So, you would have to build custom image with appropriate drivers enabled and edit OrangePi PC DT to enable one wire on PD14.

    I have done a kernel image before on a x86 machine.

    I think I have seen how to do it on armbian

    So I will look into it some more.

    It takes 2 months + to get another one here. To split the project

    Thanks
