About DMA...

[tony55723]

Hello ,

I use SDK 15.3, chip is nRF52811

If I want to use DMA+SPI, is there a reference example?

Is this DMA called easyDMA?

Thanks

Hi

Correct, when SPI_USE_EASY_DMA is enabled the SPI transactions will use (Easy)DMA. You should be able to confirm it by seeing a small current increase when EasyDMA is enabled, as opposed to when this is disabled. And yes, this is the only necessary step to enable/disable DMA in the SPI example.

Best regards,

Simon
