NRF58232/SDK15 Where can I find sample code to use NRFX_UARTE ?

[MPS]

Hi,

I'm looking for an example of how NRFX_UARTE works.

I would like to set up a serial port with EasyDMA to send and receive a thirty bytes.

Thanks in advance for your help.

Best regards,

Do you mean the Nordic UART Service - NUS?

The examples appear under the SDK in the Infocenter; eg, 

http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/examples_ble.html - Central

http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/examples_ble.html - Peripheral

Hi awneil,

Thanks for your answer but I don't want send and receive bytes by BLE, just with serial port. 

I need to use UARTE, not BLE Service NUS.

Ah - OK.

So look in the SDK documentaion:

infocenter.nordicsemi.com/.../sdk.html

eg,

Software Development Kit > nRF5 SDK > nRF5 SDK v15.0.0 > Hardware Drivers

Software Development Kit > nRF5 SDK > nRF5 SDK v15.0.0 > Examples > Hardware peripheral examples

Also refer to the device datasheet.

Thanks, but there isn't example for UARTE, just for UART.

I didn't find example code for UARTE with new NRFX_UARTE and I'm lost ...

The "uart" example in the SDK uses UARTE0 (and therefore DMA) by default.

If you are looking for a more direct way of calling nrfx_uarte_init, you could have a look at the small wrapper in nrf_drv_uart.h.

 

Cheers,
