How to modify a LCD character set?

[Darrel Taylor]

Hi flotul,

Hope it does what you need.

The normal character set is stored in ROM on the HD44780, so there's no way to change those. You're limited to just the 8 chars of CGRAM.

If you really need a whole different charset, then a Graphic LCD (GLCD) is the only way to go. But man those things are expensive. Not to mention it'll suck up a lot of program space in the PIC.

And, there's still stuff on the forum I've never even seen before. I sit in the "Who's On-Line" page alot and watch the search bot's roaming around. Almost everytime I'll see something that looks interesting that I've never noticed before. Having been here since the very beginning, it's amazing.

When you're looking for things in the forum, sometimes it's better to use the google "Site" search. Just enter site:picbasic.co.uk and then the keywords.

site:picbasic.co.uk lcd character

It also allows 3 letter words, wereas searching for "LCD" with the forums search, won't work.

Darrel,
This info is well worth a sticky post in the FAQ section!

Probably a good idea. And I think I can do even better than that.

I'll see what I can come up with.

Thanks Steve,
