"Device must be defined. See nrf.h." I've been looking for answer in Devzone , but the answers are either too old or for keil , I need a modern SES version.

As what I said in title , the answer I found was posted 5 years ago , and the interface is totally different. I just can't find where is the preprocessor selection . Can anybody give me a hand?

By the way , I can't find "nrf.h" , I can only find "nrfx.h" instead.

Please give details of where, exactly, you are getting that message.

What SDK are you using? What version?

Are you working on an SDK example? If so, which one?

Perhaps give a link to the answer you did find?

It appears in nrf_peripherals.h. I'm using SEGGER Embedded Studio for ARM V5.34(64-bit)

I'm trying to build a new project , not any of the examples.

So look at how it gets to give you that message - you need a symbol defined to specify your target chip.

You really should start from one of the examples - for this very reason!

EDIT

which is exactly what was said in the old thread - and solved the problem.

[SHALANES]

Problem solved , thanks a lot .

[awneil]

For the benefit of future readers who may come here with the same problem, please describe how you solved it.

Thanks for letting us know.

As Awneil said, you could verify the correct answer for others to benefit from in the future.
