NRF_LOG_INFO func and migrating from arduino to SES NRF52832 questions

[MikeLemon]

Hello,

I've recently properly started programming my nrf52832 DK with segger embeded studio playing a little with the debuging tool break points modifing example ect...

and I came across this function NRF_LOG_INFO(); which I guess is for outputing the info according to the parameters it takes. Now the question is where can you see them?

other questions are is there anywhere you can find a good API website for all the functions with explanations?

Also how hard would it be to convert an arduino library to be used with the SES IDE?

I have this I2C OLED display I used to control with two arduino libraries from adafruit one was for graphics handling and one for display control and I don't feel like reCoding all the algorithms there sins it's a minor and complex part of the project.

and last question is there a blog type chat where you can discuss this topic specific to SES for small questions?

It doesn't look right for me to post 1000 threads over here.

Thanks for helping.

I suspect the nrf_log_info() dumps the data to the uart (Nordic folks can correct me if I'm wrong here). You may also consider using the segger RTT in case the uart is already used to connect to another peripheral (eg. a GSM module).

The infocenter has the API description for various SDKs: infocenter.nordicsemi.com/index.jsp

So I understand that inorder to read the data coming from this function you have to connect an external device? what is RTT? can it cast data like this from the SWD port?

about the inforcer I see there is some info about functions I wanted to read about which is nice.

Now just waiting for an answer about the other library question

Thanks!

Segger RTT gets the data from SWD. The chapter on RTT in the JLink user guide provides more detailed API info on RTT usage: ~\SEGGER\JLink_V612e\Doc\Manuals\UM*_JLink.pdf

Now the question is where can you see them?

With SES you can see the RTT messages in the built-in debug terminal:

With the examples in the SDK, make sure that you in sdk_config.h have NRF_LOG_BACKEND_RTT_ENABLED and NRF_LOG_ENABLED set 1.

All this is covered in our Youtube video "SEGGER Embedded Studio - Basics of debugging", it can be found here: www.youtube.com/watch

Ah yeah thanks but there is a step in the video I can't preform sins when I right click sdk_config.h it wont show me the CMSIS configuration wizard option in minute 2:45 of the video.
