Recontrolled - By Strawberry Foundations

What is recontrolled?

recontrolled is a rewrite of the old version of recontrolled, called ledcontrol. With recontrolled you can control the on-board LEDs of your Raspberry Pi. It is currently compatible with the Raspberry Pi 4 (Kernel 6.1+) You can turn on or off the Activity or Power LED. Or even let them blink in different rythm!

How does it work?

recontrolled was originally written in C, now it has been rewritten in Rust. It directly writes to the device files using std::fs::File and std::io::Write.

How can I install recontrolled?

We offer pre-built binaries. Go to our release page (Click here) and download the latest build.

However, you can also compile recontrolled yourself on your Raspberry Pi. You need rust and cargo for this. You can compile recontrolled with the following command:

cargo build --release

Supported Platforms

To start recontrolled, all you need to do is download the executable. Just execute it and you will get a help menu.
The important thing is that you need a Linux distribution that has /sys/class/leds/ACT and /sys/class/leds/PWR Otherwise recontrolled will not work
