LCD Woes

Hello Picaxe collective :)

After a little break I am back into my tinkering. I have come across some surplus LCD modules. Not being the super savey techy I should be, I was wondering if these manuals could be put into layman's (picaxe) terms I can understand to make these work via 9600 baud serial, and maybe a little "hello world" code to get me started. If I have to dedicate a 28x2 just to run the LCD to accomplish this, so be it. Here are the manuals I was able to find on them, and hope I hope somebody can help.

The first datasheet you linked to says "Compatible with HD 44780 and HD 66780 by Hitachi Limited". That's the controller used on the lcd displays that are most common. If you want to talk to it with serial, you'll have to add your own "backpack" controller. You can buy one or make your own with a picaxe like this:

It will work at 2400 baud. You can use the AXE133 firmware to test your display.

Good luck,
Rick
