It can be done, but if you send the console output to a 4 line 20 character display it's not really usable, I have tried. It does work well with a couple of buttons as a menu to do stuff though ... Here's a 4x20 VFD on sleeve that was used for a menu http://home.earthlink.net/~wearable/galleria/jacket/ For a true console you'd need more than 4x20 characters, a lot more ... I've seen some nice ones at national control devices ... www.controlanything.com ...

That was a matrix orbital VFD that I used for sleeve display, but like I said, it's not enough characters for a console, however it works well for custom apps like GPS etc, and it makes for an excellent menu system ... > the LCD has a serial interface... anyone ever concert VGA to serial? No, this is not the way to do it ... the way is to use getty on the serial port ... I have tried it with a 4x20 LCD ... the login prompt appears. However, it expects it to be a terminal ... with the keyboard ... so a viable solution is to use a microcontroller attached to serial port and interface both the keyboard and LCD ... I have almost completed this but got distracted ... I'm working on using the Cirque pocket keyboard (small PDA keyboard) with an LCD to make a tiny terminal exactly as you describe. I have also seen code for interfacing PS/2 keyboards with microcontrollers in various places ... so you could use the twiddler or other PS/2 keyboard. -- Doug -- Subscription/unsubscription/info requests: send e-mail with subject of "subscribe", "unsubscribe", or "info" toWear-Hard Mailing List Archive (searchable): http://wearables.blu.org Please, *PLEASE* don't subscribe through a forward/expander/false domain
