Last week I got the PicoLCD. There is an open source driver for using it with the LCDProc deamon. The LCDproc provides a service which allows applications to show some information on the display.
LCDproc provides an easy to use protocol for showing your own information on the display see the LCDproc Developer’s Guide. I wrote a small python script which shows the currently playing song of a running Music Player Daemon (mpd). Since the PicoLCD provides a few buttons I added some basic control buttons (play, pause, stop, next, previous).
I have different ideas to improve this scripts but I left it this ways, because now it is quite simple and should give a good starting point for every one interested in doing something similar with LCDProc.
