https://devzone.nordicsemi.com/f/nordic-q-a/17232/nfr52-uart-with-dmaIs there any guideline on how to setup and use the UARTE on nRF52 ? what files to include in my project how to initialise the peripheral how to setup the DMA fifo how to get an interrupt when the data are on the fifo I&#39;m currentlyen-USTelligent Community 13Mon, 24 Oct 2016 14:32:10 GMThttps://devzone.nordicsemi.com/thread/66202?ContentTypeID=1Mon, 24 Oct 2016 14:32:10 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ba093b6f-4d86-43eb-87df-2f228cb8375aMartinBL<p>Hi,</p> <p>Unfortunately, neither app_uart.c nor app_uart_fifo.c take advantage of easyDMA. They only use DMA on single bytes. The only real advantages of these two libraries are a terminal-like interface (putc, getc), integration with functions like printf, and ease of implementation.</p> <p>If you need DMA you will have to use the UART driver which is documented <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v12.0.0/hardware_driver_uart.html?cp=4_0_0_2_20_0#uart_configuration">here</a>. My colleague has written an example and posted it <a href="https://devzone.nordicsemi.com/question/74615/uart-receive-in-background-without-callback-on-nrf52-sdk11/">here</a>. Note that the example is written for SDK 11. Latest SDK is 12.1.0</p><div style="clear:both;"></div>
