peripheral legacy layer config overriding the new peripheral config

[M.Anis]

when I have the line

#define SAADC_ENABLED 0

in my sdk_config.h, it overrides the

#define NRFX_SAADC_ENABLED 1

and I end up with undefined reference errors.

right now I had to comment out the

#define SAADC_ENABLED 0

line to be able to compile the code.

what's the right way to do this

I'm using GCC 6.3.1

Thanks

See this answer, where I try to explain the relationship between the NRFX and legacy definitions. Please ask if this didn't help you.

Hi Simon,

thank you for your answer.

are you saying that the new NRFX defines in sdk_config.h are not working and we should basically keep using the legacy ones?

Thanks

No, they are working. But currently the SDK is set up to use the legacy definitions, and that's the easiest approach. Let's use a silly analogy: Imagine a country with a president and a vice-president. Then the president will always have the last word and everybody listens to him, and not the vice. However, if the president is gone, everybody will listen to the vice-president.

The NRFX and the legacy definitions work the same way, the legacy definitions are the dominant ones. In order to use the NRFX definitions, you would need to remove/comment out the legacy definitions.

Best regards,

Simon
