My LCD is dyslexic

I bought my LCD screen from here:pololu.com/catalog/product/773/resources
so it uses the Hitachi HD44780 controller and is wired like the example in the BAP manual

but when I tested it out using this code

[code]lcdinit p0\p1\p7\p6\p5\p4
pause 500

lcdwrite p0\p1\p7\p6\p5\p4, [CLEARLCD,HOMELCD,SCR,twoline,“12345678”][/code]

the LCD displays: 1346578
:confused:
Help please. I don’t have any experience with LCD screens so I don’t really know how to try to troubleshoot this

P.S.
I’ve lost count of how many times I’ve checked the wiring so I’m pretty sure that isn’t the problem. I don’t even know how wiring could cause something like this so…

Check your DB4 - 7 wiring again. You’ve got a pair swapped. (DB5 & DB6?).

Robo1340,

Part of me rejoices that you solved it. :slight_smile:

My evil side is disappointed. :frowning: I wanted to see how you worked around it in long programs. :smiling_imp:
Now, we’ll never know. :imp:
