Ultra-Low Power with Energia MT and Galaxia
Power consumption is a critical feature for embedded systems, and especially for IoT devices. Reaching one year for a simple CR2032 coin cell battery is not uncommon nowadays.
Energia MT, for Energia Multi-Tasking, combined with the Galaxia library ease the implementation of ultra-low power. When idle, the MCU entres low power mode automatically.
The MSP432P401R LaunchPad was samples by Texas Instruments.
Before and After
Low power is of critical importance for sensors on IoT projects.
On the Low Power Home Network Weather Monitoring project, I rewrote the whole project around a clock and an event with Energia MT and the Galaxia library.
EnergyTrace provides great tools to measure and improve power consumption.
