Ledcontrol

Current version: 0.5.2

General info

Ledcontrol is a program that allows you to show different information on the normally-unused LEDs on your keyboard. You can configure it to show virtually any true/false condition accessible or indicate an arbitrary number. The monitoring is by default done by shell scripts to allow for maximal configurability. Included are several useful scripts.

Features include:

• blinking LEDs
• priority levels
• user-made animations
• arbitrary number indication
• GTK+ interface to test features (gled)

Ledcontrol works both in X and on a text console. I have tested it only on Linux with a i386-architecture, but it may work also on other similar systems.

Ledcontrol is distributed under the GNU General Public License.

Download

Source: ledcontrol-0.5.2.tar.gz (130 kB)

Ledcontrol is included in at least Debian (package names ledcontrol and ledcontrol-gtk), possibly also in other Linux distributions.

Ledcontrol requires GLIB version 1.2.0 or higher (GLIB 2 may not work - untested). The GTK+ frontend requires at least GTK+ 1.2.0.

Other software / sites

Some other LED-related sites and pieces of software:

• Ledsm is a light-weight monitor that can show the real-time CPU load or memory usage as a nice bar on the LEDs.
• morse2led flashes out morse code on the LEDs. This feature may be added to ledcontrol in the future, too.
• setleds, which comes with The Linux Console Tools (a standard component of most modern distribution), can be used to set / correct the LED states on a text console if wrong.
• VU Leds is an XMMS plugin allowing you to make the LEDs blink in pace with your music. Such a plugin might be made utilising ledcontrol, too.
• Kleds for those of you who don't have LEDs on your keyboard and use KDE. There used to be a similar applet for GNOME, but I can't find it anymore. (And no, ledcontrol doesn't set the state of these.)
• The LED museum, one of the greatest LED information repositories on the Net.
