where to buy font library for graphics LCD (kS0713) and PIC18F ?

There are plenty of public domain VGA/X11 fonts available for free. You'll probably spend more time negotiating and purchasing something than using them.

Rodo,

If all you need is a font, Here is one I used until we started using the ramtex which is an excellent product for the price BTW. For variable size fonts yer on your own. This maps out very well into the KS0713's memory.

You can find fonts and code all over the net as well. Just google KS0713 or one of the many compatible chips. LCD manufacturers often post sample code as well google "KS0713 LCD module"

I won't post the code( Its a bit to large ) but I can send it to you if you would like.

===========================================================

Back in the '80s I had the misfortune to own a PCB CAD package from AMS. About the only useful thing it offered was, for some reason, a font editor. I used it on several LCD projects, including one where the customer wanted black on white text so I had to build a negative character set. There probably are similar freeware editors out there somewhere...

Have a look at the following link from my website, it has some useful info and links regarding the use of graphic LCDs in embedded systems.
