Hi, what exactly mean 'could not get it to work'? Is it compilation failure? application ending in error_handler? Please provide more description

Hi, were you successful in combining SAADC and the ble_app_hrs? I tried the same for SAADC and ble_app_beacon but could not get it to work.

As RK has stated: nrf_drv_config.h contains configuration of all drivers. Peripheral driver must be enabled in nrf_drv_config.h before it can be used. It is mainly to provide overview of peripheral used in the application.

Thanks for help! Yes, I just looked at the line that error is referencing and it should be TIMER_COUNT. I don't know why compiling log comes with the missing letter though.

Hi, I tried to format your post a bit better, but it looks like some letters are missing. is IMER_COUNT correct, or did your code originally say TIMER_COUNT?

Sorry for not being able to write question neatly, but I guess somehow you managed to understand it.

I wrote this question, because saadc example does not report those errors with same setup with same define and declarations. I am newbie to programming, so I was stuck why those errors are only reported when I copied same code, .c and .h files to ble example.

for a start can you format your question so humans can read it. There are buttons for formatting output

Secondly - what do the error messages say, they are telling you that SAADC_CONFIG_RESOLUTION isn't defined plus some other ones, so you better define them? A very quick check of some of the examples shows they are defined when SAADC_ENABLED is defined as 1 in the nrf_drv_config.h file, so I'm guessing you haven't done that and have left it at 0.

The other errors are telling you you have zero-length static arrays so you probably have a zero TIMER_COUNT variable, if you don't need timers, don't use the timer module.
