Direct Memory Access (DMA)

[NNNILabs]

Hello, does Arduino Pico have DMA support? I checked the docs (https://arduino-pico.readthedocs.io/en/latest/), but I could only find references to DMA within certain audio libraries.
Alternatively, would it be possible to use the C/C++ SDK headers and functions for DMA and have it compile and run successfully?

DMA is there but there is no wrapper library, so you need to use the SDK calls directly and handle interrupts/etc. yourself. FWIW, though, the AudioBufferManager has covered a lot more use cases than I thought it would, and could be extended to a more general purpose DMA lib if someone had the time and inclination. (hint hint 😆 )

Yes, they're all included in the path and static libs. That's how the AudioBufferManager works.

Thanks a lot for the answer!
