Summary
Modern embedded systems open multiple possibilities for low-power and even ultra-low-power designs. This chapter analyzed the different energy profiles available for the reference microcontroller and how to design, integrate, and evaluate those procedures to control power usage in energy-aware embedded systems. Having understood several options available for the target, implementing low-power modes and further types of energy-saving techniques is the key to building durable and reliable battery-powered and energy-harvesting devices.
In the next chapter, we will switch focus to introducing connected devices and describing the impact of dealing with network protocols and interfaces in the embedded system architecture.
