DMA on Brush's Fat driver?

[curt2go]

Anyone attempted to use DMA instead of regular SPI on Brush Electronics Fat Driver?

LOL. That sort of does not even sound right. Anyways let me know if you have any pointers or that you think its very time consuming. I thought there would only be a few places to adjust , but I have been very wrong before.

Thanx .

I have.
It is time consuming to get right. Doesn't gain much performance at all. It is only advantageous if your code is multi-threaded. There is little to adjust in the actual code, but a lot in 'thinking'. You have to wait for the transactions to 'have happened', rather than triggering and knowing when they have completed. Since the code flow here has to wait for the transactions, you only gain if you can go off and be doing some other code while actually waiting.

Good to know. I did gain a lot of processor power back from doing DMA to my codec.

Ok I will leave it as is. Thank you for the input. As always.
