Probe increases programming efficiency for STM8 and STM32

The next-generation STLink-V3 probe for programming and debugging STM8 and STM32 microcontrollers, has been announced by ST Microelectronics. Enhancements include mass-storage support, a virtual COM port with multi-path bridge, and three-times faster write performance, says the company. The probe saves development time and easily reprograms devices in the field.

In addition to providing typical JTAG/serial-wire debug (SWD) and single-wire interface module (SWIM) connections, STLink-V3’s virtual COM port (VCP) and multi-path bridge allow communication through the microcontroller UART, I2C, SPI, or CAN interface, or GPIOs. This lets developers automate tests using custom control commands and observe run-time data on the host PC, or use the STLink-V3 to program devices with a bootloader and to simplify product maintenance.

Major development tools already support the probe, says STMicroelectronics, such as the STM32Cube programmer and integrated development environments (IDEs) such as Keil MDK-ARM, IAR, EWARM, and GCC-based IDEs. ST also allows free access to STLINK-V3 low-level APIs, for integration with custom or automated test platforms.

The STLink-V3Set kit contains the probe, debug connector, cables, and an adapter board that supports SWIM-specific features and provides access to signals from the multipath bridge. Users can further expand functionality cost-effectively with additional boards such as a voltage-translator module, adds ST Micro.
