Oliver, Bean was very useful to start display and software testing, but: 1 - We had to add some other functions (even some of them could be available in the bean) : Diplay/hide cursor, Graphic XOR mode, Clean specific area text, clean specific area graphic, ... 2 - Improve Bitmap displaying speed. Using bean, transfer is done at 1 bit (pixel) cycle while (in some cases) it can be done at 6 bits (pixels) / cycle. 3 - Bitmaps were stored as variables and thus copied to RAM (wasting scarce RAM space) while TIMAGE struct stored info not required in our app. 4 - Etc, etc. Jordi ----- Original Message ----- From: "Oliver Betz" <> To: <> Sent: Friday, May 21, 2004 1:59 PM Subject: Re: [68HC12] Graphic LCD > "Jordi Costa" <> wrote: > > > names XX-240128-X).

We use a 240x128 LCD with T6393 controller (lot of sources with generic names XX-240128-X). We start testing with code generated by Processor Expert Bean, but now using our own code.

Quinton, I've once used a Winstar B/W 320x240 SED1335 based display: WG320240B http://www.winstar.com.tw/ The CPU used was a 9S12DP256 in single chip mode. I dont recommend you the SED1335, most of these controllers have a bug that produces flicker while you are accessing it. There are other good LCD controllers like the T6963. These are some of the sites I have in my display bookmark: http://www.optrex.com/ http://www.densitron.com/display/ http://www.hantronix.com/ http://www.purdyelectronics.com/ http://www.seiko-usa-ecd.com/lcd/products/graphic_mods/index.html I was in a hurry so to driving it I've buyed a Graphic Library from RAMTEX: http://www.ramtex.dk/glcd/glcd1335.htm In my project this library was using 12 K of ROM for code, 17 K of ROM for fonts, and aprox 500 bytes of RAM. It took me a lot of work to make this library work in a banked model. (Metrowerks V1.2) I think that you can find some code in the web, but if you need proportional fonts, complex graphics, etc, the best is to use a standard graphic library.

Hey all, Has anyone here used a Graphic LCD in the near past? I'm trying to Interface a Graphic LCD to my HC12 microcontroller... Any reccomendations on the LCD and any available source code? Thanks, Quinton.
