 Post subject: AT91SAMRL64, using the DMAC with SMC?

Hey guys, I inherited this project from another person and have a lot less hardware experience than I should have in order to be in charge of something like this, but, that's life, right?

So I have a situation where my screen is hooked up to the SMC (I think?) on CS0, and I send it a 0x22 at 0x10000000 to begin a full screen copy, then I write 16bit values at 0x10000004 for each pixel for a 240x320 screen that is attached. Obviously, doing this on the Atmel uses a lot of processor time, about 24ms each time I do it -- I'd like to try and use the DMAC on the Atmel instead to do this, or maybe the PDC (but I don't think it works for this?), but I'm having trouble deciphering the Atmel PDF docs since my hardware experience is so minimal.

Any help pointing me in the right direction would be awesome! Let me know if you have any questions (probable!) and I'll do my best to answer...

No responses? :(

How about this, are there any code examples available for using the DMAC either in the AT91Bootstrap or in AT91 Linux?

Please, any help you guys can provide would be great!
