  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 ഇന്റർഫേസ്.

  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 voltagഇ ക്രമീകരണങ്ങൾ.
  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.
