Project idea- LCD terminal

UnixDork · Post by **UnixDork** » Tue Feb 26, 2002 1:05 pm

This has probably been brought up a million times before, but I don't see anything about it in a search.

I'd like to make an LCD serial terminal, aka a dumb terminal. I know I could use a serial LCD to output text to, but I'd like to have full blown terminal emulation. Does anyone here have any information on where to start?

thanks for any help you can offer.

Ex2 under MO's programming examples might be a good place to start. I wrote this to test my LCD.

Are you wanting to use a keypad (somewhat limited) or the console keyboard? Or both???

Do you only need basic screen formatting such as FF, NL, CR controls or full formatting that allows such things as forms input?

It would be a real interesting exercise to build an LCD termio definition with infocmp (unix utility). You could then write a curses based application to achieve your goal.

I was looking at having the LCD as another terminal, you can type commands to it, and execute the commands and then it will output the results

Problem is, the display I have is too small, I need a 40x4 or something like that to make it manageable.

I think this is just what you need:

it can have a standard keyboard connected to it, and it has a large screen, perfect for what you want to achieve. the only thing left is to write some software for it.

That would probably be ideal, but using the small fonts on the GLK12232 then I have 32 chars a line, and a standard keyboard would be used anyway for the software.
