PWM Fan Control for 3 pin / wire GPIO fans for Raspberry Pi

    • New

    Hi,

    This pwm-gpio-fan overlay has recently been merged with Raspberry Pi OS, can it be added to, or used with Libreelec?

    GitHub - herbingk/pwm-gpio-fan: Raspberry Pi device-tree overlay for a GPIO connected PWM cooling fan controlled by the software-based GPIO PWM kernel module

    At the moment I've been using this method to control the fan.

    Raspberry Pi Legacy Tools Add-on

    I would like to know the reasons why the RPi.GPIO library was dropped from the Raspberry Pi Tools add-on. In my opinion, this is a mistake. I'll explain. I am the author of the OLEDproc plugin. It depends on several libraries, including the luma.oled and luma.core libraries. And therein lies the trouble. The luma.core library needs the RPi.GPIO library to work. I am convinced that it is unthinkable and also pointless for me to create some clone of the luma.core library, which would use, for…

    From a current LE13 nightly with RPi Linux 6.12.y kernel ^ - I don't have an LE12 device but we bumped the kernel for the 12.0.2 release (shipped last night) so if RPi devs backported the change to their Linux 6.6.y kernel it should be included there too.
