The actual technology of the display shouldn't matter (VFD, LCD, LED, TFT). When I last looked into these displays they were generally controlled via a serial port (which will likely appear via an internal USD cable). Once you have the serial port, it probably show up under Linux as: /dev/tty-something or a similar name with USB. Generally they take a stream of text data, with high-bytes [beyond the normal ASCII range] being used for control commands; such as to clear the display. Sometimes the display can handle font downloads or even bitmap data. The simplist test command is likely: echo Hello World | sudo tee -a /dev/ttyUSB0 The next step is to find a daemon that will take information from your system (temperature, uptime, SCOX stock price), format the information and submit the complete printed line to the display at regular intervals. These guys are one of the well-known suppliers: http://www.matrixorbital.com/ >From a quick 'apt-cache search', daemons for running under Linux and controlling the attached LCD display module would be: gpsim-lcd - LCD module for gpsim gpsim-lcd-graphic - LCD module for gpsim lcd4linux - Grabs information and displays it on an external lcd lcdproc - LCD display driver daemon and clients procmeter3 - graphical system status monitor mgm - A highly configurable, very gaudy system load meter It might be that somebody else has more recent experience; 'lcdproc' rings a bell somewhere in my mind as being familiar. -Paul -- Why do one side of a triangle when you can do all three.
