SPI and DMA

Post by con3 » Mon Jul 30, 2018 11:18 am

Hey everyone,

Is it possible to use the DMA with SPI?

I want to receive data via SPI and have the DMA fill a buffer, once the buffer is filled I want the DMA to alternate to a secondary buffer and have the CPU stream the first buffer to a python interface on my PC.

Thanks in advance for any help!
