'[PIC] LCD graphics interfacing'

A never ending supply of fun is what I have....

OK, I had posted a request for pointers to large character LCD/VFD displays, but nothing out there really seems to fit the bill.

So...now I am looking at the larger graphical LCD modules, but thats a big step away from the simple HD44780 interface.  This box is a one-off demo for the client to take with him and demo his product, so I really hate to go all out but it will eventuall migrate to a product so what I do now should hopefully be used then....thats why I wanted to stick with a simple character LCD module.  I could use a graphical tho, just in a smaller package, for the product.

So, anyone written an interface to drive characters to these devices from a PIC?

If you just need a one-off product, why not buy one of Scott Edwards'
products, they are designed to be easy to use and the pricing is not bad
for a single item.

A few years ago I wrote some stuff in C18 to do that. As I recall, I took
some standard fonts, ran them through some sort of font converter program
that gave me C constant arrays for each character. I then had an array of
"strings" of pixels for each character. When I wanted to output a
character, I just sent the appropriate string of pixels. The output
character routine indexed into the table of pixels. To output a character,
you also had to specify the position on the display. When outputting a
string, I also passed in the starting x,y coordinates of the string. As
each character was put on the screen, I added the width of the character
(they were constant width) to x, then output the next character.

So... that's the general approach. This, again, was done in C18. The code
is buried here somewhere. I did that SEVERAL years ago...

For a one off demo unit, if the size of the display surrounds etc is
not too critical, then a Toshiba Libretto can work wonders. Old,
cheap, marvellous. Talk to them via RS232. Completely different from
the finished product so it depends which part of the system the
demonstration is meant to emphasise.
