SAADC

[DEGHI]

I need to include in my project Advertising, buttons and battery power measurement.

I am using SDK 15.2

If I get  ble_apps_bps and include advertising functionality (from ble_app_beacon example ) no problem all work weel.

If i get saadc example all work well.

But when I try to include battery power measurement. in my file (derived from ble_apps_bps  & ble_app_beacon ) I get an error.

I activated the specific module and building is ok but when I debug the application I get an error in nfrx_timer_init:

but the code is the same that in saadc example where all work well.

Many thanks for your help

Hi,

Which timer instance are you using? Note that the softdevice use and blocks access to TIMER0, you will have to use another instance for SAADC sampling. Can you share the code used for configuration of timer and SAADC?

Best regards,
Jørgen

Hi Jorgen, many thanks for your answer. I chose to use an application timer (app_timer_start).This way I have no problem.I decided to use an aplicative timer also because I seem to have understood that this consumes less energy. it's correct?

[Jørgen Holmefjord]

Yes, that is correct. App_timer library use the low frequency RTC as the clock source. This consume less power than the TIMER peripherals that require the HFCLK to be running.
