is it possible to mirror the charictors on the hd44780 controler, and if it is what are the commands to do it. I am trying to setup a car hud, but if i cant, i will just put it in the dash.

thanks

is it posible to reverse the horizontal rows on the screen so that you could mount the screen just like it would be facing you to get the correct effect. you could then use the regular letters. And i do mean reversing the wires going to the screen.

ex.
1 01111
2 01000
3 01000
4 01110 (the letter F)
5 01000
6 01000
7 01000
would become
7 01000
6 01000
5 01000
4 01110
3 01000
2 01000
1 01111

how hard would it be to cut and solder in wires to reverse the horizontal rows?

With an extreme amount of patience and some very fine soldering skills, this could be done.

There would only be 16 horizontal lines to do and typically all the lines on a module go through a via from the controller on the back of the PCB to the contacts on the front. You would have to make 16 cuts and 16 jumpers (2 solder connections per jumper = 32).

I would not expect success on my first try.
