Alternative to the H44780 lcd controler

[Sphere]

Thanks for the reply skimask. I’m using the Batron BTHQ42003AV display, I can access line 1 and 3 using the LCDOUT command but only the first 12 characters of those lines, anything after that just copies part of what’s showing on line 1 on line 2. I need to figure out how to enable access to the rest of the display, but unfortunately this is where I draw a blank. It looks like you have to enable the EXT pin to enable access to the rest of the display but I do not know how too.

Thanks Sphere.
