In my project there are two ways to wake up the STM from standby mode, one is the RTC wakeup timer (regular) and the other is PA0 WKUP (spontaneous), but is there a way to detect that it has been woken up by PA0 and perform a specific function?

Hi jasonas.matas,

The example under STM32Cube_FW_F4_V1.9.0\Projects\STM32F429I-Discovery\Examples\PWR\PWR_CurrentConsumption can be helpful for you.

But, if you are developing an application with standby mode, be careful to taking into account the workround mentioned in section (2.1.3) of the

http://www.st.com/st-web-ui/static/active/en/resource/technical/document/errata_sheet/DM00068628.pdf

 related to STM32F427/437 and STM32F429/439.
