As of version 1.97.5 the EPSON E0885-2 lcd display is part of serdisplib and officially supported. Thanks Wolfgang!

This page is about using the Epson E0855-2 LCD display (distributed by Pollin Electronic) under linux.
Pollin sells this display and the adapter kit for the parallel port at 2,95 € each (which is very cost-effective). The total cost is 5,90 € (September 2006).
One only needs the usual skills with the soldering iron, only when attaching the display to adapter's PCB you have to be careful (lead-wire spacing 0.8 mm! - as seen in the pictures below).
With only 96 x 32 px resolution the display will maybe not be very useful with VDR or GraphLCD. It works quite well with

E0855-2 Linux Support
The lcd display is driven by serdisplib's SED153x driver, which can be found at http://serdisplib.sourceforge.net/.
Many thanks to Wolfgang Astleitner for this great lib!
Officical support for the E0855-2 display will be (presumably) included in serdisplib-1.98. Meanwhile you can try your luck with my changed source files. I've used serdisplib-1.97.2 as the basis and I've changed the following files a little bit:
Remarks on using /dev/parport0To use the display as non-root user via /dev/parport0 you have to have the ppdev module loaded. Just issue a modprobe ppdev and check the permissions + user/group for the device file.
