SPI to Memory transfer (PGDMA)

[User12977]

Hi,

I'm trying to read the input from an SPI interface trough GPDMA to the memory of an XMC4800.

In detail:
With a high interrupt frequency (PWM) I'm sampling the SPI interface.
On every interrupt when the frame length of the SPI input is reached, I want to shift the SPI FIFO to the memory over the GPDMA.


How do I achieve this?

Thanks
Patrick
