TMS320F28379D: issue regards DMA

Part Number: TMS320F28379D


I need help regards DMA data send process, is there any way to implement some delay between two SPI DMA frame (words /16 bit). 

Thank you

  • Hello Akash,

    The DMA transfer can be created using a specific trigger such as from a peripheral or software trigger. If you don't want to rely on some event from the SPI peripheral, you can use the software trigger to manually configure when you want the transfer to happen. There is no inherent feature in the DMA to add a delay in the transfer, this is something you will have to manually do in your program.
