Thread: Unicorn GLCD demo.

Here is a simple demo using a graphic LCD on Bill's Unicorn.

My C is a little rusty and the C18 compiler with the Harvard architecture makes it a little more challenging. I did however manage a few routines that should get people started.

This is what it looks like when it's working,



As you can see, I'm not an artist and my version of the Canadian Maple leaf leaves a lot to be desired.

This should work with any pic18 and a GLCD with two KS0108 controllers. It is however a lot simpler with the Unicorn.

The attached zip file contains the c files. Comments and constructive criticism welcome. Thinking about it, the lack of comments in the code will probably be most commented on.

It looks fantastic Mike. Well done and the leaf looks great.

Did you try the scope software I attached to an earlier thread.

Mike have you ever heard of Conways Life? This is what I'd like the demo to do. I figured on using only half a display for a 64x64 board. I wonder what a maple leaf does in life?

PS can I use the photo with the leafs on my site? Will give credit to you of course.

It was a lot easier than I thought. Only took half an hour - I'm starting to like C18.

Here is Life on the Unicorn. There is just a glider and a small exploder on there at the moment.

Wow it looks very nice to me.Does it take much current/Voltage to the GLCD?

Data sheet here.

Your Demo is really nice sir and should encourage many other enthusiasts to start experimenting.Once Bill, being a canadian, has acknowledged the Maple leaf what more.

Same to you Pommie - nice graphics!

hi Mike,
As its 0.1inch pin pitch I would use a male/pin connector.
This will match up with your project board and also give it the 'stand off' height above any pcb/project board socket... Have a relaxing xmas break...
