DMA on the way!

[AsafFisher]

Implement the DMA api for all the peripherals :memo:

[tdittr]

Things I had on my list for the DMA:

• Example: https://docs.rs/stm32f1xx-hal/0.7.0/stm32f1xx_hal/dma/index.html
• Traits: https://crates.io/crates/embedded-dma

[AsafFisher]

Thank you for the guidance! I will look in to it (:

[AsafFisher]

I dont like https://crates.io/crates/embedded-dma's traits why should I follow them?

[tdittr]

Well, I guess it would allow more interoperation, similar to the embedded-hal traits.

What is the status of this implementation?

@maximeborges The branch where this work took place is https://github.com/rp-rs/rp-hal/tree/rp-dma It has not been touched in 7 months. I would call the status of this implementation "abandoned". Use it as a starting point if you wish, but if you a need for DMA I suggest starting a new branch and working on it rather than waiting for this to be finished.

See #209 for a more complete take on DMA which is already usable.

How is it going? Is there any working on progress?

No progress

I have been using the PR #209 in my project (details in this comment: https://github.com/rp-rs/rp-hal/pull/209#issuecomment-1156582772 ) I have rebased the change to the recent branch in https://github.com/slint-ui/rp-hal/tree/dma-0.6

[9names]

I did a rebase of your rebase earlier today. https://github.com/9names/rp-hal/tree/dma-0.6 The plan was going to write + run some tests to see what works, maybe clean up the implementation and write some docs

[ogoffart]

That would be nice to see that merged. I also tried to upgrade to embedded_dma 0.2 in https://github.com/slint-ui/rp-hal/tree/embedded_dma2 (which i just pushed now), but i haven't tried it yet.
