The new probe features mass-storage support, a virtual COM port with multipath bridge, and three-times faster write performance. 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 multipath bridge allow communication through the microcontroller UART, I2C, SPI, or CAN interface, or GPIOs.
Major development tools that support STLINK-V3include STM32Cube programmer and IDEs such as Keil MDK-ARM, IAR EWARM, and GCC-based IDEs. ST also allows free access to STLINK-V3 low-level APIs.
The STLINK-V3SET contains the probe, debug connector, cables, and an adapter board that supports SWIM-specific features and provides access to signals from the multipath bridge.
