https://community.nxp.com/t5/LPC-Microcontrollers/eDMA-LPC55/m-p/1580685#M51242 <P>Hi,&nbsp;</P><P>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&nbsp; calling&nbsp;USART_TransferReceiveDMA after each reception ? Is there any example for uart dma continuous transfer with a ring buffer for LPC55?</P><P>Regards.</P> Wed, 11 Jan 2023 08:50:07 GMT ahmedhrabi 2023-01-11T08:50:07Z https://community.nxp.com/t5/LPC-Microcontrollers/eDMA-LPC55/m-p/1580685#M51242 <P>Hi,&nbsp;</P><P>I'am trying to implement continuous uart dma reception, but i didn't found the eDMA functionality on the LPC55.
