Hi team,

We want to use SCI communication by DMA, but I can't find SCI DMA trigger source. Does it mean DMA cannot work in this way? I also find another way: configurate LIN in SCI mode and this seems can be supported by DMA. I'd like to know your suggestions. Great thanks!

    Hi,

    Thanks for your question!

    As you mentioned, the SCI peripheral does not have DMA support, however, the LIN peripheral does have DMA support for its SCI mode!

    Could you try the "lin_ex3_sci_dma.c" example and let me know if this suffices for your example needs? This example may exactly match what you are requesting!

    It is located here:

    C2000Ware_VERSION#\driverlib\f28002x\examples\lin\lin_ex3_sci_dma.c

    Regards,

    Vince
