Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

I haven't given up on the Raspberry Pi receiving serial data and driving the large lcd screen yet. Its just unfamiliar territory, but should be feasible. One downside of this is the need for a 240vac supply for the screen.


For a large alphanumeric display I used a 32 inch LED TV and an rPi. The rPi drove the TV via HDMI.

There were a few things to manage in different ways. I pulled all of the icons off of the desktop, used a blank desktop image, and hid the top bar. This resulted in booting up to what looked like a blank screen.

I ran a python script/program on powerup. This script created an output window (with no window decorations like a close button) and simply displayed text in the size/colors that I wanted in the screen positions that I wanted.

Serial input was captured and processed to change the contents of the display.

All of that was done in python 3.

Thanks for the info. My son has played with python a bit and can probably make sense of your description. I have been investigation freebasic but producing different sized fonts seems possible but a bit involved. I'll probably get a chance to play with a rPi in the next few days.
Your setup sounds pretty much what I had in mind.
