I have not heard any response to my follow-up. Is there a Nordic engineer assigned to look at this issue?

Thanks,

Jackson

Thanks for the information about steps to include peripherals. I have done this successfully with the SAADC.

However, even following these steps, there were several points where NRFX_CHECK() failed. For example, the saadc_sampling_event_init() routine calls nrf_drv_timer_init(), which fails to build:

This occurs because the first #define in nrfx_timer.c calls NRFX_CHECK(), which fails:

This happens even though NRFX_TIMER_ENABLED has been set to "1" in sdk_config.h:

If I comment out this NRFX_CHECK() (and several others) build succeeds.

This situation appears for other drivers (like nrfx_ppi) as well. The #define in sdk_config.h does not seem to be affecting the driver file's compilation.

This is also a nice tutorial for importing files and drivers in SES.

It goes without saying that you need to include driver's .h file into your main file

Hi,

[quote userid="79066" url="~/f/nordic-q-a/70810/add-saadc-peripheral-and-others-to-example-project"]How to properly add peripherals to a project -- the documentation and Devzone are very incomplete on this topic.[/quote]

1. Include the driver/library to your project

2. Enable the driver from the sdk.config.h file

3. Ensure that driver's/library path is included in preprocessor directory

I do not know.. could you share the error?

It doesn't affect the compilation if the driver is disabled.
