hi, does anybody know urls where i can find info or proyects using PICs to control a graphic display (320x240 o at any res)?
thanks

I'm looking for the same myself, so if you find anything be sure to post it up here...

ok, i could only find a proyect where they use a pic to control a graphic display from nokia cellphones, but what im looking for is to control larger display like (320 x 240) as i said. if anybody posts this kind of info i would be very gratefull.
ok, bye

using only a pic would be very difficult, the amount of data that has to be sent to a LCD without a controller on it is imeanse, just flick through the data sheet for one of the LCDs your looking at and do the maths, even a 40Mhz PIC couldn't drive a 320*240 LCD alone.

Try using a controller like the SED1330/5/6. (i have some code that covers basic stuff, init/setup/command issuing, for the G2446 on http://www.eio.com/g2446ap.htm $25 its quite a bargin imo.

Once you have a controller you don't need to constantly refresh the LCD with information. So the pics (which are slow) can do simple animation and stuff.

If you realy don't want to use a controller like a 1330, then try looking at some of ARM's products, these RISCs are often upto 100mhz, and still low on battery power!

Can you post the link? Thanks.

Here's a link to a pic graphic lcd project. It's only 240X64. The largest graphic lcd that I found using the built-in Toshiba T6963C controller is 240X128.

this is the link with source code for controlling a graphic lcd (the one i mentioned before - nokia)

Well I'm not so sure about needing 100MHz RISC to drive the LCD...

I have a HMD (Xybernaut) and it uses Altera EPM 5032LC-25 to drive the 640x480 monochrome display. It receives RGB+H/Vsync and puts that out into the 1" microdisplay

What I'm trying to do myself is make something similar to drive a Kopin 320x240 monchrome microdisplay 0.7" in size.

This was posted in another thread here but in case others dont read, this is an awesome link:

http://www.rickard.gunee.com/projects/

Rickard talks about generating video signal using PIC (b/w) and SX (colour) controllers...just plain awesome stuff and there are links to more "good" readings related to the subject.
