LCD Problem

[skimask]

Wired all data lines but still have the same issue, but it looks like it treats lines 1 & 2 as line one and lines 3 & 4 as line two. Is there any limitation in picbasic pro's lcdout command for this type of display. The display type is Batron BTHQ42003AV, ive ordered a replacement anyway just in case this one is faulty.

Would've been a lot more helpful to have the model information a lot earlier.
The model you've got has a controller that isn't 100% Hitachi 44780 compatible.
Seems it likes to work in blocks of 12...which would probably explain your issues.
In the case of this LCD, the standard 1st line ($80), 2nd line ($C0), 3rd line ($94), 4th line ($D4) addresses aren't going to work.
Here's the link to the datasheet:

Read thru it a bit. You may/may not see what I mean...specifically page 364, 384, and 419.
