Hi everyone!
I am using Kinetis K64 and it's SDK. I need to send a value (16 bit in this case) repeated times (N) using SPI and DMA. Creating a buffer of N and filling it with the value and then using the "DSPI_MasterTransferEDMA" API would work, but I want to avoid it (creating the buffer).
I know that setting the correct values in the TCD of DMA it is possible to copy N times the same value (using a -2 minor loop offset for example), but I can't find the way to access the TCD using the SPI DMA driver (fsl_dspi_edma).
Is there a straightforward way of doing this sticking to the transactional api mechanism?
Thank you very much!
Tobías
