Hi all,
Anyone messed around with LCDProc before? I had a 4x20 LCD lying around, so I thought I would give it a try on my Linux box, and it works! I also installed the lcd-stuff utility that lets me see what's playing on phpMP, and maybe even control it once I get the keypad to work...
I compiled lcdproc and lcd-stuff from source, so I am feeling quite l33t just now. The only snag I found was that the LCDd daemon had to be run as root or it would just crash without doing anything. For wiring, I used the 8-bit "Winamp" connection to the parallel port, and took power from a USB port.
Finally, I seem to remember someone here saying that they had a bunch of 4x20 VFDs... you wouldn't want to sell me one? :)

Yay, I've now added a 16-key keypad, and hacked lcd-stuff to implement proper CD player-style controls for mpd. So linosaur can now pass himself off as a CD player with Play/Pause, Stop, Previous Track, and Next Track buttons.
This was remarkably easy to do, as lcd-stuff was written in plain C and well thought-out and commented. The design of lcdproc also made it easy to generate and register new keycodes, so all that needed changed was about 10 lines of code in lcd-stuff's mpd.c. God bless open source!
