Application note
Introduction to STM8L15x power saving modes
using the STM8L-DISCOVERY I
DD
measurement feature
Introduction
This application note introduces some of the power saving modes available in the STM8L
microcontroller family. The STM8L-DISCOVERY has a built-in I
DD
measurement feature that
is used to demonstrate the real capabilities of the STM8L15x microcontroller’s low power
modes.
This application does not require any additional hardware. Once the STM8L-DISCOVERY is
powered-up through a USB cable connected to the host PC, the application is ready to
dynamically display the STM8L power consumption in each of the different modes selected
by the user.
This software example comes preloaded with your STM8L-DISCOVERY and is readily
accessible at application power-up.
