STMicroelectronics reveals STM32 programming/debug probe

▤ Summary

Having a wide dynamic range to handle power-conscious projects including IoT and wireless applications, the probe measures current values from nanoamps to 500mA and remains accurate up to ±0.5%. STLINK-V3PWR is supported directly within the STM32CubeMonitor-Power graphical tool, which helps visualise the power demands of the application in real-time and analyse the effects of design changes to improve energy efficiency. “Ultra-low-power microcontroller applications use energy harvesting or run for years on batteries, however small design errors can create unexpected power issues,” said Reinhard Keil, Senior Director, Embedded Technology at Arm. The µVision debugger can correlate program events with power consumption, providing analysis to help developers identify potential design errors and enabling multifold improvements to battery lifetime.” Anders Holmberg, CTO at IAR added: “Full support for the STLINK-V3PWR probe within IAR Embedded Workbench for Arm allows developers faster and easier access to power analysis that is both accurate and repeatable, and with high resolution. It is sure to help realise greater energy savings and efficiency gains in next-generation ultra-low-power and ultra-efficient smart, connected devices while also drastically accelerating their time to market.” STLINK-V3PWR adds further strength to the energy-conscious embedded developer’s toolkit alongside the STM32 Power shield (X-NUCLEO-LPM01A), a programmable power supply source that provides dynamic current measurement from 100nA to 50mA.
