IWRL6432: Obtain the RTC time

HI, there:

In the motion and presence detection demo, you can find the function Cycleprofiler_getTimeStamp() at motion_detect.c.

Hi.

With this Cycleprofiler_getTimeStamp() this function gets whether the time is divided by the clock frequency 40

HI.

I need to get the RTC real-time clock type time to be used as a real-time clock. Get a year, month, day, minute and second based on the start of 1970, while Cycleprofiler_getTimeStamp() can only return a 32-bit CPU runtime in microseconds. The 32-bit time radar will overflow after a short period of time, so it is obviously not a good idea to run it for a long time using Cycleprofiler_getTimeStamp(). Since I can achieve this on iwr6843 with the ti.sysbios.hal.Seconds module, how can I get the same effect on iwrl6432 platform?

Hello,

If what you are looking for is what the RTC count is at, you could read just read the RTC register. You can see how it is read within the MMWAVE-L-SDK at source/drivers/prcm/v0/prcm.c.

你好。

RTC寄存器的地址是多少？请提供。

最好的祝愿

Hello,

According to Google translate you are asking for the RTC register, below is a picture of its addresses. Look at physical address.

HI.

These two addresses represent the high and low of the counter, which is a 48-bit RTC counter. All I have to do is combine the values at these two addresses into a 48-bit value to get the count, right?

Best Regards

HI.

Thank you very much for your help.

Best wishes.
