Does F280049C's SCI(UART) port has DMA function? If it does, where can I find the example code.

Thanks!

Hi Wen,

Thanks for your question! The F28004x does not have DMA availability on SCI.

Thanks! Understood F28004x does not have DMA on SCI/UART now. What about the F28388D's SCI/UART?

Hi Wen,

F28388D UART peripheral (not SCI) has uDMA (micro DMA) support as described in the TRM. There is a loopback example available in C2000Ware at the following location:

C2000Ware_*VERSION#HERE*\driverlib\f2838x\examples\cm\uart\uart_ex2_loopback_udma.c

Thanks again!.

Okay, I see, the UART in CM does have DMA support.
