Multisample DMA for SAADC?

[BartMassey]

I'm sampling audio (the microphone on the micro:bit v2) using the NRF52840 SAADC. It would be great to set up a DMA to be able to capture multiple successive samples rather than blocking per-sample. Any advice on setting this up? Is there anything already present here for that that I am missing?

Thanks much for any help you can give.

There is an open PR similar to this I never came about finishing: #233

Thanks for the pointer! I'll try to find time to take a look at this.
