RE: TMS570 SPI in client mode using DMA

Other Parts Discussed in Thread: TMDS570LS12HDK, HALCOGEN

Jean-Marc this is great and runs well on my TMDS570LS12HDK but it there an example showing how to do just a simple SPI slave without the DMA? The DMA just seems like magic and all I want to do is get individual bytes from an off-board master SPI.

    Thomas,

    Splitting onto it's own thread ... if you attach to an old thread it's easy to get the question lost.
    Better to make a new question and link to the other thread (just paste a the URL to the thread you are referring to).

    If you transmit & receive with only the CPU not DMA, then look at example_SPI_Master_Slave.c
    in HalCoGen's example folders. It shows you the API for either polling or interrupt driven transfers.
