I would like to use a KS0108 type for a terminal (it is desirable for its low power use, around 5-7 amps), I cannot seem to find drivers and would like to know where to start on writing my own drivers or hacking together something that gets around it.

If possible can I make a virtual HDMI port or Character LCD that I can use to control the screen over GPIO? If not, what would be the best place to start to learn how to write drivers?

Never used that kind of screen, but this is supposed to drive it.

EDIT: how to read and write data from and to terminal in python. You'll need to import os:

import os

Then, to write a command to the terminal use, ie:

os.system('ls')

and to read from it:

print run_command('your_command_here')

EDIT2: I don't know if this will work, but seems to me like the better aproach if possible:

Create a software serial port under GPIO and wire the hardware serial port to the serial software port, then, create a python script that starts @reboot and reads the terminal TX and print it on the screen.

EDIT3: I've found this. Seems to explain how to create more uart ports.

  • I saw that but it seems its not actually drivers, it just allows you to control the display with python. – 8o7wer Sep 15 '17 at 0:54
  • I'm thinking that maybe it's possible to create a sketch that reads and write to the terminal, but not sure if that would be completely possible. – Luis Diaz Sep 15 '17 at 6:06
  • that would work but I'm not familiar with console interactions in python and I dont know how to deal with programs that take inputs (ex the python console) and what to do about curses(ex nano). – 8o7wer Sep 15 '17 at 6:10
  • I've edited the answer to add info about the terminal, but I don't know if this will fit you, because it will only get the output form the command that you send, not the whole terminal. – Luis Diaz Sep 15 '17 at 6:41
