[nRF52832] SPI DMA Usage

[Robotics Gun]

I am using nRF52832 for high-rate sensor.

Of course, I can use SPI using CPU but it's busy for other jobs. 

So I want to use DMA if it's possible.

Currently I am using NCS 2.6.1

I checked other Q&A but below repo not containing overlay files for 52-DK.

Isn't it possible to use SPI DMA at 52832?

Hi

NRF52832 does have a SPIM (SPI Master with EasyDMA) peripheral. 

You can use an overlay for the DK based on the DTS information.

As a sample, you may like to look at SPI lesson which does have overlay for 52DK (written for that particular sensor).

Ok. I found nrfx driver included inside Zephyr Official Repo and I ran it on 52DK.

Every thing works fine and I got the expected result.

I just want to make clear for nrfx driver in zephyr.

Question: Nordic is doing/planing any work to have zephyr RTOS API level for peripheral DMA? (Not just for SPI. I meant all the peripherals with DMA).

If not, I think you guys will keep the nrfx driver.  I hope getting proper answer!

No, I don't think there is anything planned like that.

Yes, NRFX drivers will be there.
