nRF 52832 UARTE support

[Santhoj]

Hi All,

I am using UART with baud rate 4800, with even parity and 1 stop bit. I'm getting 6-8 bytes in a packet. I'm receiving packets for every 8-10ms continuously. This affect the processing speed of main process. So I'm planning to use UART with DMA (UARTE). But I didn't find any support for UART with DMA. Can you please tell me how to enable DMA support for UART.

Thanks, Santhoj I

Hi Santhoj,

Have you checked standard UART HW peripheral example from nRF5 SDK? It uses DMA on nRF52 (see #define UART_EASY_DMA_SUPPORT 1 in \examples\peripheral\uart\pca10040\blank\config\sdk_config.h file.)

Hi Cheers Jan,

I'm using SDK11, in that I didnt find this path.

Thanks, Santhoj

Hello Thanks Santhoj,

There is the same example in nRF5 SDK V11, it just doesn't contain sdk_config.h because that concept was introduced later but otherwise it does all the job including using DMA.
