T6963 / RA6963 LCD controller with PBP

[HenrikOlsson]

rmteo,
Well, I wouldn't call myself a developer but yes, I write some code from time to time. If you follow this forum I think you'll find that I usually don't ask for much compared to what I give so I definitely don't expect to be "spoon fed all the time".

My tongue-in-cheek reply was aimed at the fact that I wonder exacly what that latest post of yours was supposed to do? It doesn't help me or anyone else one single bit that you've done it if you don't want to share how - as I said I already KNOW it can be done so seeing yet another photo of a GLCD really doesn't help. And the rest about other displays, which I guess are used other microcontrollers and other compilers and RTOS'es doesn't help much either but thanks anyway.

Thanks again for the Swordfish link though, that helps!


Mark,
Thanks a bunch, that helps as well!
I've seen Mike and Ranjits site several times yet I didn't remember to check it now that I needed it.

A little more time with Google though dug up this Hitatchi app note on the T6963 filling in a couple of gaps in the datahsheet.

/Henrik.

You can try this. This was made for a 240x64 T6963 display but it might work with yours. Ive added the ports your display uses. You will have to set you config bits and osc speed for the pic. Its the best I could do for you.

Hope it helps Sphere.

Thanks!
I got it going today though, displaying text, but I'll use yours to get further ideas from.

I'm still confused about how the physical resolution of the screen maps to "software resolution" and fontsize control etc. I'm playing with it as we speak so I'll figure it out - possibly.

Thanks again for sharing!

/Henrik.

The GLCD I think is a bit difficult subject. I tried once and left it for a later time.

Every contribution is most welcome. And since Henrik has a 'Contributor' level it means that is a great giver. So post #7 is not very appropriate answer especially to Henrik. He deserved a better one. Or do not answer at all.

Really? I posted a link to another BASIC site that provided source code. Is only providing PBP source code considered a better one?

Perhaps here. As I said, I posted a link to another BASIC site where they developed a library/driver for T6963 as well as KS0108 GLCD's - they don't seem to have problems.

Yes but you need a good understanding of that other basic lanquage...

Agreed. And that is why I consider coding ability alone (particularly if you are limited to a single specific language) a pretty insignificant skill.
