NRF_LOG MACROS to SEGGER_RTT?

[MANGO]

Hi, I use PCA10040 v1.1 with Keil MDK 5.20 and SDK 12. I have installed J-Link 5.12f driver.

I usually use the NRF_LOG_ENABLED MACRO to check the UART debug message.

It seems to me that the SEGGER_RTT can be an alternative way to check log messages.

So I was wandering that can the NRF_LOG_INFO MACROS can be changed to SEGGER_RTT_WriteString without searching every MACROS in the application code.

The "find and replace" the NRF_LOG_INFO MACROS was kind of a troublesome.

So, instead of using "find and replace", can the NRF_LOG_INFO MACROS be replaced to SEGGER_RTT?

// Added 2016.09.06

I used the SPI master example by the way.

I used NRF_LOG_ENABLED and NRF_LOG_BACKEND_SERIAL_USES_RTT as a preprocessor. (Don't know whether this is a correct expression.)

Or change the values in the sdk_config.h.

As a result, it works! Thanks, Krzysztof Chruściński and Keton.

Yes, nrf_log supports RTT as one of possible backends. In sdk_config.h you can find an option NRF_LOG_BACKEND_SERIAL_USES_RTT that needs to be enabled (NRF_LOG_BACKEND_SERIAL_USES_UART should be unset then).

Weird, if I try

NRF_LOG_INFO("Info with integer parameter %d\n\r", 10);

it works, but

NRF_LOG_INFO("Info with string parameter %s\n\r", "some string");

I get:

error: #167: argument of type "char *" is incompatible with parameter of type "uint32_t"

EDIT:

Nevermind, nrf_log_push() seems to take care of that.
