This driver supports displays from [[http://tilofranz.net/lcdshop/|LCDShop24]] using the **LCD-USB-Interface** by [[http://wallbraun-electronics.de|Wallbraun Electronics]].

The displays are fully graphical with a resolution of 320x240 pixels. The driver supports loading of a background image, therefore the results look //really// cool:

Have a look at the [[:CoolStuff|Cool Stuff]] page for a larger picture!

The driver needs a special library called "libLUIse" which can be downloaded from [[http://www.wallbraun-electronics.de|Wallbraun Electronics]]. //configure// tries to detect if the library is available, and otherwise disables the driver.

Since 2008-10-14 there are additional informations about V3 controller with documentation of the protocol used. Wallbraun Electronics will not publish own Linux drivers for the V3 controller.
