STM32W Power management

Question asked by on Mar 16, 2012
I am currently using the STM32W for a research project. My professor wanted me to look more into the Power Management of this chip. I am still very new to coding with these chips and I am having some trouble with trying to figure out just how the power management system works. I've read the documentation and everything but still I cannot seem to figure it out. 

What I want to do is put the chip into different states of sleep, and calculate the time it takes for the chip to run a couple mathematical functions. I will be able to time functions and calculate the efficiency for each state. 

Any and all help is welcome with this. Thanks
