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.

Did you set this in your sdk_config.h file and re-compile the whole project (clean first, then build)?

#define NRFX_UARTE_ENABLED 0

 

The first error is because nrfx_uarte.c is still enabled, and the second is due to the "nrfx_prs" library being used by nrfx_uarte is in use.

I have : 

NRFX_UARTE_ENABLED 0

NRFX_UARTE0_ENABLED 0

NRFX_UART_ENABLED 0

NRFX_UART0_ENABLED 0

UART_ENABLED 1

UART_EASY_DMA_SUPPORT 1

UART_LEGACY_SUPPORT 0

UART0_ENABLED 1

UART0_CONFIG_USE_EASY_DMA 1

NRFX_PRS_ENABLED 1

NRFX_PRS_BOX_4_ENABLED 1

Could you try to remove the nrfx_uarte.c and nrfx_prs.c from your project and see if it works then?

Thank you, it seems to work now. I test it all and come back here to say if everything is ok.
I will not have compatibility problems with future SDKS?

[Håkon Alseth]

Glad to hear that it works now.

A general rule is that as long as you do not add or use any modules that depends on the UART peripheral, it should be fine. As you're doing a bare-metal implementation, it is _very unlikely_ that the register definitions will ever change for the current device that you are using.

However; I cannot guarantee that a module that you require in the future does not depend on the UART in some way (for logging or similar).

 

Best regards,

Many thanks for your help. I think I can do what I want now.

Ok for the compatibility, I understand.
