I want to implement nrf_calendar with RTC3

[zester926]

Hi, Devzone.

Well, I found the calendar library from the following link. https://github.com/NordicPlayground/nrf5-calendar-example

By the way, I'm using RTC0 for Softdevice so I should change it with RTC3.

I tried to change defines (which are in nrf_calendar.h) to RTC3 but, It couldn't be compiled.

Is there any good examples that I can check?

I'm using nRF52840 DK with s140 and Segger embedded studio.

Best regards,

Baek

Hi,

There is no RTC3 in nRF52840. The chip has 3 RTC instances, RTC0, RTC1, and RTC2. Typically RTC0 is used for softdevice, RTC1 is used by app_timer library, and RTC2 is available for other uses in the application.

Best regards,
Jørgen

Thank you Jørgen!

I solved it from changing with RTC2.
