STM32 Power Shield : EEMBC-approved power-monitoring technology for energy-critical embedded development

To check the power consumption of embedded designs accurately, the STM32 Power shield (X-NUCLEO-LPM01A) provides developers an affordable tool with an ideal measurement range for ultra-low-power devices, such as Internet-of-Things (IoT) endpoints.

The STM32 Power shield features voltage supply to the target from 3.3V down to 1.8V, dynamically monitors the current under various operating conditions from 100nA to 50mA, measures static current from 1nA to 200mA, and also performs direct EEMBC benchmark measurements with a fast acquisition rate of 3.2 Msample/s. The STM32 Power shield has indeed been selected by EEMBC as the reference platform (Energy Monitor v2.0) for the IoTConnect and ULPMark benchmarks.

Firstly, with its built-in display, the STM32 Power shield can be used autonomously without the need of any external equipment. Secondly, its companion graphical PC application STM32CubeMonitor-Power (STM32CUBEMON-PWR) aims at setting parameters of the STM32 Power shield and visualizing the data captured to help developers meet their budget of power consumption. STM32CubeMonitor-Power also optimizes acquisition and parsing operations to flawlessly process the millions of measurements captured every second by the STM32 Power Shield without requiring expensive computers. Furthermore, this application includes a command line version so developers can use their favorite scripting language to perform custom test sessions and exploit all the information in their own applications.

The STM32 Power shield provides an accurate tool to measure the energy consumption of ultra-low-power devices. Together with the STM32CubeMonitor-Power graphical application, users will be able to analyse energy measurements and make better-informed decisions.

STM32 Open Development Environment

The STM32 Open Development Environment (STM32 ODE) is an open, flexible, easy and affordable way to develop innovative devices and applications based on the STM32 32-bit microcontroller family combined with other state-of-the-art ST components connected via expansion boards. It enables fast prototyping with leading-edge components that can quickly be transformed into final designs.

The STM32 ODE includes the following five elements:

STM32 Nucleo development boards. A comprehensive range of affordable development boards for all STM32 microcontroller series, with unlimited unified expansion capability, and with integrated debugger/programmer

STM32 Nucleo expansion boards. Boards with additional functionality to add sensing, control, connectivity, power, audio or other functions as needed. The expansion boards are plugged on top of the STM32 Nucleo development boards. More complex functionalities can be achieved by stacking additional expansion boards

STM32Cube software. A set of free-of-charge tools and embedded software bricks to enable fast and easy development on the STM32, including a Hardware Abstraction Layer, middleware and the STM32CubeMX PC-based configurator and code generator

STM32Cube expansion software. Expansion software provided free of charge for use with STM32 Nucleo expansion boards, and compatible with the STM32Cube software framework

STM32 ODE Function Packs. Set of function examples for some of the most common application cases built by leveraging the modularity and interoperability of STM32 Nucleo development boards and expansions, with STM32Cube software and expansions.

The STM32 Open Development Environment is compatible with a number of IDEs including IAR EWARM, Keil MDK, mbed and GCC-based environments.
