Ledbridge is our main software for controlling LED-Displays.
Ledbridge is our main software for controlling LED-Displays. It was initially developed in 2008 to replace the proprietary, windows-only software LedShowT9 and allow the LEDsMob to be controlled from Linux systems. Since then a lot of features have been added to it. It's modular design allows it to capture frames from all kinds of sources and drive various kinds of displays. Ledbridge is primary designed for Linux systems but, while lacking some Linux specific features, it has also been successfully tested on Mac OS X and FreeBSD. Windows is not supported at the moment. Like all of our software it is open source and can be obtained from our ledtools repository.
The screenshot on the right shows ledbridge capturing a 48x64 pixel part of the screen - in this case a part of a fractal generated by XaoS - and transferring it to a T9 display attached to eth0, the default interface. The content "below" the highlighted capture window is processed.
The input modules currently supported by ledbridge are:
It can optionally process the frames by applying a filter to them:
... and send it to various displays:
The typical usage scenario is to capture frames from an X11 or AWT source and transfer it to a display. But we also provice add-on software for generating text or video frames without starting an X-Server. This allows ledbridge to run on embedded devices such as a Sheevaplug:
