Hi Hitesh,

Are you referring to a Real Time Clock? If this is the case, you will have to use an external one and find a corresponding driver.

But if you are referring to a Real Time Counter, then you should refer to the Counter API that I mentioned in the previous reply. Or if you just wish to use a timer, you can check the Timers.

Regards,

Priyanka

Hi Priyanka,

Thank you very much for quick response,

I have a question, as we can observe in this link of RTC & RTC interfaces is having an implementation towards Maxim ds3231 as same observed here in this path of zephyr driver - \nCS\v1.8.0\zephyr\include\drivers\rtc

currently we are having an dvk_653 board having nrf52833.

can you pls add more inputs or a direction so that we can have a development on the bl653, specifically we are looking for zephyr apis for RTC

Thank you,

Regards,

Hitesh

Hi Hitesh,

You can refer to the following:

RTC

RTC interfaces

Also, all RTC peripherals in Zephyr are implemented with Counters with device specific APIs.

Can you pls share document / path of Zephyr related RTC api's to be referred

as we can observe in nCS\v1.8.0\zephyr\include\drivers\rtc we have header for maxim_ds3231.h & mcp7940.h

do we have any zephyr based api's as we can see for other peripherals in nCS\v1.8.0\zephyr\include\driver folder

Hi Hitesh,

You could refer to this unofficial GitHub page for a sample. In case you wish to learn or work more related to timing, you can also checkout the Zephyr kernel timer.
