lan951x-led-ctl is a command line tool to control the LEDs connected to a

LAN9512 or LAN9514 ethernet controller.

Usually those LEDs show the ethernet status like "Link/Activity", "Speed" and

"Duplex" mode. Using this tool you can turn them off, if you don't like

a disco in your room at night ;-) Or you can turn them on/off from any shell

script to show whatever status you wish.

These LAN951x ethernet and USB controllers are used on many embedded computers

like Raspberry Pi (until Version 3B - but not 3B+), Olinuxino and many more.

The Git repo with the latest version is located at:

https://git.familie-radermacher.ch/linux/lan951x-led-ctl.git

Compile:

    make

    step-by-step:

        sudo apt-get -qq install git libusb-1.0-0-dev  #  will also install: libusb-1.0-doc

        git clone ...

        sudo make --directory lan951x-led-ctl DESTDIR=/usr/local

        rm -rf ./lan951x-led-ctl

        sudo apt-get -qq autoremove --purge libusb-1.0-0-dev

Usage:

    sudo lan951x-led-ctl [--fdx=x][--lnk=x][--spd=x]

        where x is one of:

        0 - turn LED off

        1 - turn LED on

Automate:

    sudo tee /etc/systemd/system/rpi_blinkenlights_set_to_off.service > /dev/null <<- EOF

        [Unit]

        Description=to configure the RPi NIC LEDs to off

        [Service]

        Type=oneshot

        ExecStart=/usr/bin/sleep 15  #  RPi1; can be smaller on RPi2/3

        ExecStart=/usr/local/bin/lan951x-led-ctl  --fdx=0 --lnk=0 --spd=0

        RemainAfterExit=no

        [Install]

        WantedBy=multi-user.target

    EOF

    for an example, see systemd-folder

    sudo --askpass systemctl enable --now --no-block rpi_blinkenlights_set_to_off.service
