I have added a USB soundcard and some speakers to my Slug, this is described elsewhere in this wiki. Now I also wanted to add a LCD, and preferably use a homemade USB-attached LCD (as decribed here: http://forums.bit-tech.net/showthread.php?t=115461(approve sites)).

I started out with installing the kernel module for the display:

ipkg install kernel-module-cdc-acm depmod -a modprobe cdc-acm

The display is at /dev/ttyACM0:

dmesg ... drivers/usb/class/cdc-acm.c: This device cannot do calls on its own. It is no modem. cdc_acm 1-2.3:1.0: ttyACM0: USB ACM device[br] usbcore: registered new driver cdc_acm drivers/usb/class/cdc-acm.c: v0.25:USB Abstract Control Model driver for USB modems and ISDN adapters

To make use of the display Lcdproc is installed...

ipkg install lcdproc

...and configured:

nano /etc/LCDd?.conf


  1. Matrix Orbital driver ##


  1. Select the output device to use [default: /dev/lcd]


  1. Set the display size [default: 20x4]


  1. Set the display type [default: lcd; legal: lcd, lkd, vfd, vkd]


To get info from the mediaplayer MPD to LCDProc? the script mpclcd (<a href="http://lcdproc.spacedout.nl/download.php?file=mpdlcd.pl(approve sites)">(Link)</a> is used. This is not to fun to install, and it does not even get installed :(
