Post by thread:Graphic LCD Example Code.

Friends, I *finally* got ahold of a couple graphic LCDs ("AND" 128x128) and was hoping somebody might have some sample code. This project is going to be cool when I finish it!! I have a 2 1/2 year old son who loves ughhhhhh "teletubbies". I figured I would make him a small toy that will play different "episodes" (that I write) depending on what button he presses. I am going to hook the graphic LCD to a PIC16C67 or a 16F877. The PIC will also have a large external memory to hold the "episodes". Then I will also have some music to go along with the episodes, as well as a voice playback module that I can make them "talk" to him. Sounds COOL doesn't it. To get started I was hoping somebody would be kind enough to share some assembly they used. I realize this project is going to be VERY expensive, but if I wanted to have money, I would have never had a child. ;-) I am using a di splay with a T6963C controller. I appreciate your opinions and help. Thanks alot!

I have used an external controller from Cybernetics Micro (http://www.controlchips.com <http://www.controlchips.com> ) CY325. This is an intelligent graphics/text controller for lcd displays up to 128x240. Communication to the CY325 is parallel or serial. The CY325 talks to Toshiba based lcd displays. David V.

I think the Tiger processor would be perfect for this. It has several routines ready for T6963 controller. You will need a lot of memory for this, maybe a SmartMedia card or a MultiMedia card, both known as 'digital film'. I'm interested in this project as well.

But he already has a T6963 controller ... I am considering an LCD (with such a controller) and a PIC interface to a 16C72 or the same as he's using. I have an ICE PIC Jr which emulates a 16C74 at the moment and can handle 16C72. I have not really started it yet since we're evaluating off the shelf serial LCDs (text) and haven't decided whether to migrate to an equivalent 4x20 sized graphic display. If it were a 16C74 target (overkill) or the 16F877 (which has PSP I believe) I would consider connecting the LCD T6963 interface specifically to the parallel slave port (CS\ etc) after checking the timing specifications. On the 16C72 I have considered (a little!) driving the control strobes in software but this may or may not be too slow.

Yes he is using a Toshiba based controller - this is what the CY325 talks to. I guess the main advantage of using the CY325 to me is the reduction in the number of control lines needed (3 vs ~ 11) David V.

It was up as of 8/15/99. If you go to http://www.vermontlife.com and click on the embedded ethernet link that gives the same error that you found. Maybe he moved his site? I don't know. The author is Gary Desrosiers. In his application he interfaces a 16f84 to a T6963 controlled display. He demonstrates the whole project with an assembly program to draw lines and a graph on the screen. I have the asm source around here if you want.

Jim, I have the asm file. It is about 20k, so I will mail it to you John ----- Original Message ----- From: Jim Paul <jamespEraseME.....INTERTEX.NET> To: <EraseMEPICLISTMITVMA.MIT.EDU> Sent: Tuesday, October 05, 1999 10:52 PM Subject: Re: Graphic LCD Example Code. > John, > > I tried again, but got the same error.
