• Pin 3 (GND): Ground
• Pin 4 (SWCLK): SWD clock
• Pin 5 (NRST): Reset
• Pin 6 (SWO): SWD output (optional)

Usage

1. Programming:
   • Connect the ST-LINK/V2 to the target microcontroller using the appropriate interface (SWIM for STM8, SWD/JTAG for STM32).
   • Use supported software tools (e.g., STM32CubeProgrammer) to flash the firmware onto the microcontroller.
2. Debugging:
   • Connect the ST-LINK/V2 to the target microcontroller.
   • Use supported IDEs (e.g., STM32CubeIDE, Keil, IAR) for debugging, including setting breakpoints, stepping through code, and inspecting variables.

Notes

• Driver Installation: Ensure that the ST-LINK/V2 drivers are correctly installed on your PC.
• Firmware Updates: Regularly check for firmware updates for the ST-LINK/V2 to ensure compatibility with new devices and features.
• Connection Verification: Verify the connection between the ST-LINK/V2 and the target microcontroller to avoid communication issues.
