STMicroelectronics has introduced a brand new programming and debug probe for STM32-family microcontrollers, the STLINK-V3PWR, which incorporates high-accuracy energy measurement capabilities.
“Extremely-low-power microcontroller purposes use power harvesting or run for years on batteries, nonetheless small design errors can create surprising energy points,” says Arm’s Reinhard Keil in help of STMicro’s newest debugging software. “The brand new STLINK-V3PWR probe allows energy profiling with [Arm’s] Keil MDK. The µVision debugger can correlate program occasions with energy consumption, offering evaluation to assist builders establish potential design errors and enabling multi-fold enhancements to battery lifetime.”

The STLINK-V3PWR {hardware} itself presents the same old performance of a debug probe, with JTAG and Serial Wire Debug (SWD) connectivity to a goal microcontroller, a digital serial port with multi-path bridge for SPI, UART, I2C, CAN, and general-purpose enter/output (GPIO) communication, and the power to flash new firmware on to a goal machine.
It is the probe’s power-profiling capabilities which makes it stand out from the competitors, nonetheless. STMicro claims the gadget can measure present values from the microamps as much as 500mA with an accuracy of ±0.5 per cent, whereas offering as much as 2A of energy to the goal system by a single USB cable.

“Full help for the STLINK-V3PWR probe inside IAR Embedded Workbench for Arm permits builders sooner and simpler entry to energy evaluation that’s each correct and repeatable, and with excessive decision,” provides IAR’s Anders Holmberg of his firm’s software program, which has introduced launch-day help for the probe alongside Arm’s Keil MDK.
“It’s positive to assist understand larger power financial savings and effectivity positive aspects in next-generation ultra-low-power and ultra-efficient sensible, related gadgets whereas additionally drastically accelerating their time to market.”
The probe is now obtainable within the channel at $93.10; extra data is out there on STMicro’s web site, together with a obtain of the corporate’s in-house graphical energy monitoring software STM32CubeMonPwr with STLINK-V3PWR help.
