You evidently need to call and pester a CSR to get a copy of one.
I think I've found one; a website somewhere said that there's a 64 byte chunk of RAM, CGRAM, on many LCDs, which can be used to store custom-generated characters. So that's definitely good, and it can store up to 8 characters, which is also good.
Problem though is still that without that datasheet, which may be sitting on a server at work, I can't put together any code to get it to do what I need.

I'm going to be doing some LCD interfacing tonight too. :thumbsup:
Interesting, I've got a fair bit to read, apparently. I wouldn't have even known enough to have been looking for a "controller" sheet.Originally posted by: Leros

As far as your project goes. Be aware that that LCD already has a controller on the back. Probably the HD44780. That controller exists on most of those character displays. So you want the datsheet for that chip. HD44780 data sheet

The two datasheets available at Digikey are only one page each, and aren't particularly useful - kind of like a GPS module I had to work with. Its entire datasheet was also two pages long. Page 1 was more like a product brochure, and page 2 had the pinouts. That was pretty much it.
Its replacement has a manual/datasheet that is 47 pages long, plus a firmware and commands guide that is 103 pages long. THAT is a datasheet.
(Or the PIC chip I've had to work with, it's got >300 pages.)
I'm getting a crash course on electronics and computer engineering while at this job. My college time was for mechanical engineering.
Not that I'm complaining.
