Abstract
| USB LCD |
|
| These instructions are essentially for a USB LCD Display[1], a USB docking Palm-OS device can emulate a USB LCD interface so that no external adapter is needed. The same instructions could be used with some modification to add an LCD with: Add a Serial port to the PowerPC Linkstation as a matter of fact someone on the kurobox wiki has done just that[2] |
This article is for people that want to add an LCD display to their Linkstation but don't want to crack it open[3], and happen to have a USB cabled Palm OS [4] device lying around. Using PalmOrb [5] you can emulate an external (20x4),(40x4) or (26x16) character LCD display.
Prerequisites
This article assumes that you have installed FreeLink. A 2.6 Kernel Upgrade to the 2.6-kernel (ppc only) has better USB support, but a 2.4 Kernel would probably work as well. For these instructions you will need a USB cabled Palm-OS Device.
Method
- Install PalmOrb on your USB cabled Palm-OS Device. The v1.1a4[6] version has the most font options for a (20x4) emulated LCD, there are several other versions available on Sourceforge[7]. It emulates a Matrix Orbital LK204-25 LCD.
|
|
|
Configure the PalmOrb app to use the USB Port: Menu -> Options -> Serial:Device:USB |
- Install and remove LCDproc using apt-get (this should take care of any dependencies) The Debian Stable Version only has the LCDd Daemon program but not the lcdproc client, so you'll have to install lcdproc from a tarball. Kind of an ugly solution to get the dependencies resolved, but it works:
apt-get install lcdproc apt-get remove lcdproc
- Get the LCDProc[8] tarball and compile/install it. Make sure you have installed the Precompiled C development environment, running on the LS first.
wget http://lcdproc.omnipotent.net/download/lcdproc-0.4.5.tar.gz tar -xvzf lcdproc-0.4.5.tar.gz cd lcdproc-0.4.5 ./configure make make install
- Use these instructions to configure LCDProc to run with PalmOrb properly[9] make sure that the MtxOrb part of /etc/LCDd.conf looks at least a little something like this:
........ [MtxOrb] # Matrix Orbital driver # Select the output device to use [/dev/lcd] device=/dev/ttyUSB0 #device=/dev/usb/tts/1 #device=/dev/ttyS1 # Set the display size [20x4] size=20x4 ........
- You may have to initiate the appropriate module for the palm[10]
modprobe visor
- Attach the USB enabled Palm-OS device and start the PalmOrb app. Do a dmesg of your linkstation; if things went well you should see lines like this at the end:
usb 3-1: Handspring Visor / Palm OS converter now attached to ttyUSB0 usb 3-1: Handspring Visor / Palm OS converter now attached to ttyUSB1
- Run the LCDd (LCDproc Daemon) and LCDproc client with some options to see if it works.
LCDd & lcdproc C M X
- Hopefully you got some output on the Palm-OS device as an LCD. For other clients Google:lcdproc to see what other LCDProc clients you can find. Or just go here[11]
What's the point?
| Palm as Terminal (untested) |
|
|
| Enable terminal access with this command: getty -h -L ttyUSB0 9600 vt100, and use a terminal program like ptelnet[12] |
Well if you happen to have a USB enabled older Palm OS PDA lying around and want an external LCD display for the price of nothing, now you have it!
Shell Scripts
#!/bin/sh # lcdmon.sh # Kill any LCDd that are running first, Start the Daemon and # fork it to the background. Then run LCDProc with the Time option and # fork it to the background. # You can run lcdproc -? alone to see what options there are. # Run another client: netlcdclient which gives U/Dl speed # You could run this script at startup. killall LCDd LCDd & lcdproc T & netlcdclient -i eth0 -a LinkSTN -d
