Hi,

The repo just has a Prova_controllo.lnk file, which I am not sure what is. Can you just push your project (so project files for whichever toolchain you are using, code files, etc) to your GitHub? Remember that it should be complete so that it would build if I dropped it in a newly extracted nRF5 SDK. Then you are sure everything is included.

Hi, thanks again.

I have tried again but nothing. Of course, I upload the project. I you could give a brief look thanks very much.

That does not really mach the error you wrote you get (stating that NRFX_SAADC_CONFIG_RESOLUTION is undefined), unless you undef it or the preprocessor excludes it. If you still have not solved it, you can upload your project and I can have a brief look to see if I spot the cause.

Hi,

I check and NRFX_SAADC_CONFIG_RESOLUTION is declared in this way in the sdk_config.h

#ifndef NRFX_SAADC_CONFIG_RESOLUTION
#define NRFX_SAADC_CONFIG_RESOLUTION 1
#endif

I also compare the sdk_config.h file from which I take the code with my new sdk_config.h file and the code related to saadc is the same

Hi,

If you have the snippet from your original post in your application's sdk_config.h, then NRFX_SAADC_CONFIG_RESOLUTION will not be undeclared. Can you double check that this is not inside a block comment, or that you have not added it to the wrong sdk_config.h file by accident (from another project or similar).

Thanks for helping.

I tried to correct th sdk_config.h file, but it still does not compare.

Also, I tried to include "nrf_saadc.h" and "nrf_drv_saadc.h" library in the main file, but when I build there are errors.

For example, one is:

'NRFX_SAADC_CONFIG_RESOLUTION' undeclared (first use in this function); did you mean 'NRF_SAADC_INT_RESULTDONE'?

They are all in nrfx_saadc.h file, which I have not modified, so I think the problem is due to the import and enable of the driver.

Thanks again

Hi,

The CMSIS configuration wizard will have problems displaying the sdk_config.h file in the GUI if there is an error in the tags it uses. Here it looks like you are missing a line with "// </e>" at the end. (This has no effect on the preprocessor and compiler though, it is only a problem for the GUI).
