1. Okwu mmalite

The ST-LINK/V2 is an essential in-circuit debugger and programmer designed for the STM8 and STM32 microcontroller families. It facilitates communication between your development environment and the target microcontroller on an application board.

This device utilizes two primary interfaces for communication:

  • Single Wire Interface Module (SWIM): Used for STM8 microcontrollers.
  • JTAG/Serial Wire Debugging (SWD): Used for STM32 microcontrollers.

The ST-LINK/V2 connects to your computer via a USB full-speed interface, enabling seamless interaction with various integrated development environments (IDEs) and programming software.

Once the ST-LINK/V2 is connected and drivers are installed, you can begin programming and debugging your microcontrollers.

4.1. Programming and Debugging STM8

For STM8 microcontrollers, the ST-LINK/V2 uses the SWIM interface.

  1. Open ST Visual Develop (STVD) for debugging or ST Visual Program (STVP) for programming.
  2. In your chosen software, select ST-LINK as the programming/debugging tool.
  3. Configure the target microcontroller settings, including the SWIM interface speed (low-speed or high-speed) and application voltage.
  4. Load your firmware or project into the software.
  5. Initiate programming or debugging as required by the software interface. The status LED on the ST-LINK/V2 will blink during communication.

4.2. Programming and Debugging STM32

For STM32 microcontrollers, the ST-LINK/V2 uses the JTAG/ SWD interface.

  1. Open your preferred IDE (e.g., Atollic TrueSTUDIO, IAR Embedded Workbench, Keil MDK-ARM, TASKING).
  2. In the IDE's project settings or debug configuration, select ST-LINK as the debugger/programmer.
  3. Ensure the correct interface (JTAG or SWD) is selected and verify the application voltage ntọala.
  4. Build your project and load the executable onto the target.
  5. Start the debugging session or program the flash memory. The status LED on the ST-LINK/V2 will blink during data transfer.
