Controlling LEDs and the push button under Linux

Rack Matrix Technology has developed an open source driver for Linux to manage the 3 LEDs and the push button on the front panel. This driver opens the possibility for all application developers to display different information about their application through the switching on or off of the LEDs as well as an interaction with the push button. We have written an article about its use on our website.
