Open Energy Profiler Toolset

Modular open hardware Energy Profiling

Battery-powered devices often incorporate high-speed communication protocols that consume power in high peaks. One of the main challenges is to provide a compatible set of hardware and software solutions that will enable easy and high-precision energy profiling tools which enable high-speed sampling rates and high current rates.Energy consumption profiling of such devices requires the use of various hardware and software solutions that are often not compatible, making them difficult to use, or do not provide suitable measurement accuracy. Our primary objective is to provide a unified toolset that encompasses an EEZ bus compatible hardware platform, open-source firmware, customized protocols for external firmware energy debugging, and a user-friendly graphical interface for widely used operating systems like Windows and Linux. This toolset will enable the end user to quantify overall MCU-based device consumption and identify energy-intensive software parts within an IoT end device. The project outcomes will include an EEZ Bus compatible standalone acquisition card that support sampling data rates up to 4 MSPS and high-speed data streaming through an Ethernet interface; an open-source library as support for energy debugging of end device firmware; and open-source GUI application for visual examination of different energy consumption parameters.
