1. Introduzione
The STLINK-V3SET is a modular, stand-alone debugging and programming probe designed for use with STM8 and STM32 microcontrollers. This device consists of a main module and a complementary adapter board, providing comprehensive functionality for development and testing.
It facilitates communication with target microcontrollers via SWIM and JTAG/SWD interfaces. Additionally, the STLINK-V3SET offers a Virtual COM port for host PC communication through UART, and bridge interfaces (SPI, I2C, CAN, GPIOs) for programming via bootloader. Its modular design allows for feature expansion through additional modules, such as the adapter board.

3.3. Collegamento del dispositivo
- Connect the STLINK-V3SET Main Module to your computer using the provided USB Micro-B cable. The device is self-powered via USB.
- If using the adapter board (MB1440) for SWIM or bridge interfaces, connect it to the main module as required.
- Connect the appropriate debug cable (e.g., STDC14, MIPI10, MIPI20) from the STLINK-V3SET to your target STM8 or STM32 application board. Ensure correct pin orientation.
- Verify that the power and communication LEDs on the STLINK-V3SET illuminate, indicating proper connection and power.
4. Istruzioni per l'uso
4.1. Debugging STM32 Microcontrollers (JTAG/SWD)
- Ensure your development environment (e.g., STM32CubeIDE, Keil MDK, IAR Embedded Workbench) is configured to use ST-LINK/V3 as the debugger.
- Connect the STLINK-V3SET to your STM32 target board using a JTAG or SWD cable.
- In your IDE, initiate a debug session. The STLINK-V3SET will establish communication with the target microcontroller.
- You can now step through code, set breakpoints, inspect variables, and perform other debugging operations.
4.2. Programming STM8 Microcontrollers (SWIM)
For STM8 programming, the adapter board (MB1440) is required.
- Connect the adapter board (MB1440) to the STLINK-V3SET Main Module.
- Connect the SWIM header from the adapter board to your STM8 target board.
- Use the appropriate programming software (e.g., STVP) to load your firmware onto the STM8 microcontroller.
4.3. Virtual COM Port (VCP) Usage
The VCP feature allows your host PC to communicate with the target microcontroller via UART.
- Ensure the STLINK-V3SET is connected to the target via the STDC14 debug connector.
- On your PC, identify the assigned COM port for the STLINK-V3SET VCP.
- Use a terminal emulator program (e.g., PuTTY, Tera Term) to open a connection to this COM port with the correct baud rate and settings.
- Data sent from your PC will be relayed to the target microcontroller's UART, and vice-versa.
4.4. Multi-path Bridge Interfaces (SPI, I2C, CAN, GPIOs)
These interfaces are available on the adapter board (MB1440) and allow for direct communication with peripherals on your target board.
- Connect the adapter board (MB1440) to the STLINK-V3SET Main Module.
- Wire the specific SPI, I2C, CAN, or GPIO pins from the adapter board to your target device.
- Utilize the ST-LINK utility software or custom applications to interact with these bridge interfaces.
4.5. Drag-and-Drop Flash Programming
The STLINK-V3SET supports convenient drag-and-drop programming for compatible microcontrollers.
- Connect the STLINK-V3SET to your target board.
- The target microcontroller may appear as a removable drive on your computer.
- Drag and drop your compiled firmware file (e.g., .hex, .bin) onto this drive to program the microcontroller.
