RTC example for timestamp (STM32WB55)

[kcire L.]

Hello,

I'm looking for some example code on using the built in RTC for the STM32WB55 to get a timestamp in UNIX UTC Time in milliseconds. Or the number of milliseconds since January 1st 1970.

If anyone has a simple example on how to accomplish this I would greatly appreciate the help.

Thank you in advance.

Hello @kcire L.​ ,

Maybe you can get inspired from RTC_TimeStamp example within STM32CubeWB MCU package:

\STM32Cube_FW_WB_V1.12.0\Projects\P-NUCLEO-WB55.Nucleo\Examples\RTC\RTC_TimeStamp

This example runs on STM32WB55xx devices and will help you on the RTC configuration using the timestamp feature.
