The ST-LINK/V2.1 and ST-LINK/V2 from 7SEMI is a USB-based programmer and in-circuit debugger designed for STM32 microcontrollers. It allows developers to program and debug STM32 microcontrollers via the SWD (Serial Wire Debug) or JTAG (Joint Test Action Group) interfaces.. STM32 applications can communicate with the STM32CubeIDE software tool or third-party integrated development environments via the USB full-speed interface.
The ST-LINK/V2.1 and ST-LINK/V2 tool features a high-performance embedded ST-LINK/V2 server that supports firmware upgrade and allows the user to easily change the target MCU by simply connecting the corresponding adapter board. The tool supports a wide range of STM32 microcontrollers and is compatible with major third-party IDEs such as Keil, IAR, and Eclipse.
The ST-LINK/V2.1 and ST-LINK/V2 provides real-time debugging and allows developers to set breakpoints, step through code, and monitor variables in real-time. It also provides access to the MCU's memory and peripherals, which enables the user to analyze the behavior of the system and identify issues.
