eDMA LPC55

[ahmedhrabi]

Hi, 

I'am trying to implement continuous uart dma reception, but i didn't found the eDMA functionality on the LPC55. Is there any method to receive uart data through DMA continuously without  calling USART_TransferReceiveDMA after each reception ? Is there any example for uart dma continuous transfer with a ring buffer for LPC55?

Regards.

Hi @ahmedhrabi 

LPC55 USART+DMA, we only have these two demos:

We can find them under SDK folder.

Besides, we don't have others.

Have a nice day,
