I recently got my hands on a Seiko G191C21R0A graphic lcd-display.. The data-sheet says that it has a 4bit parallell interface so it should be possible to connect it to the parallell port.. Now i know nothing of writing software so does anyone else know how to use it? Any comments greatly appreciated.

Not familiar with that display, but there is a good chance that the "4-bit" they are talking about is the interface to the drivers, not to a controller chip. In that case you would need a driver board too.

Graphic lcd G1216-SOS

Hi, everyone!! I have a project about connecting a G1216 lcd to a system with the microcontroller 89S8253. I've done the hardware part but now I have to program the lcd in C in order to draw a dot, a line, a rectangular and insert a pic from the PC. Is there any software available because I'm running out of time......Thanks in advance!!!!!!

I don't understand why you have added your post to the end of an 8.5 year old thread. Was there some connection to the previous material?

Have you searched for any code for your processor or display? What do you have so far?

Wow, this was a long time ago. I do however have something to help you.

Now, if i recall correctly the G1216 is a Seiko model, using a Hitachi controller that i don't recall the number of, but if i again recall correctly is KS0108 compatible.

In that case this will be of interest: http://panic.klippanlan.net/elektronik/ks0108.tar.gz

It's a complete driver written for AVR-GCC and includes all the functions you're after. I have no idea if it exists code for the AT89 series, but this should be enough to get you through.
I didn't write it, so don't blame me for the java style function names. It was written by Korken at Elektronikforumet.com.

I thought there was a connection since the title is about a graphic lcd. Maybe I should have started a new thread! Sorry!:)

I have found some lcd management routines in assembly.
