Lascar Sp 5-gfx1 Glcd

[Calco]

Hi all,
Ive just bought a LASCAR SP 5-GFX1 Graphic LCD, I was wondering if anyone else had used these. Lascars website hasnt helped very much.
It is a serial interfaced display, however I cannot find what baudrate setting is appropriate, whether it is true RS232 or the sticky variety.
Any help would be greatly appreciated.

Regards

Darryl

Hi

Thanks for the prompt reply,
I have been there, downloaded all datasheets. Read them many times.
I try to do that before asking for help.
Iam still lost however.

Hi Calco,
I think you may have a bit more work to do. From a quick look at the datasheet, the serial input to this display is NOT any form of RS232. It is a synchronous serial port. I.E. it needs a clock as well as data. There is no Baud rate as such. In PBP this means using the SHIFTOUT command.
You need to setup the display driver and then send in a 0 or 1 fro each of the 8192 pixels. This is 1KB of data! Most developers generate the graphics data using a PC program. The Lascar site had a link to such a program. The amount of data is such that you may have to use external memory to store graphics.
These displays are not accessed by simple text strings like the 16x2 alphanumeric LCD's

Not much help I know but I hope I've given you an idea of what you need to do.
