Hello,

I would like to use the real time clock, integrated in the CC2652R1.

Do you have some examples ?

Thanks,

Hi Sebastion,

What is your use-case for the RTC?

The "Clock" module in TI-RTOS is actually running of the RTC, which means you could use this to run timers of the RTC timer if you could accept some jitter in the responds. This is the most straight forward way and the recommended one if it is sufficient for your task.

If this for some reason is not enough, you could potentially use "Channel 1". Keep in mind that anything you do in this ISR would add some delay for any other Clock callback that is expected to be invoked. Please see the TI-RTOS API documentation for information on how to use this channel:

I'm sorry for the number of posts..

Function get_Seconds gives me the count in seconds, but I need to do a calender so there are not a function which gives me the date (year, month, day, hours, minutes and seconds) ?

Thanks,

Best regards,

Sebastian

Hi Sebastian,

No, there is no calendar functionality in the RTC module. There is also no such module in TI-RTOS. You would need to define your own SW module for this (much like the TI-RTOS seconds module is simply a wrapper around the RTC value).
