To enable these powerful features, install the [STM32Cube for Visual Studio Code](https://marketplace.visualstudio.com/items?itemName=stmicroelectronics.stm32-vscode-extension), [CMakeTools](https://marketplace.visualstudio.com/items?itemName=ms-vscode.cmake-tools), [Cortex-Debug](https://marketplace.visualstudio.com/items?itemName=marus25.cortex-debug), [Embedded Tools](https://marketplace.visualstudio.com/items?itemName=ms-vscode.vscode-embedded-tools) extensions, [OpenOCD](https://openocd.org/) and the [STM32CubeCLT](https://www.st.com/en/development-tools/stm32cubeclt.html) software package. The latter one is required for downloading the firmware right away using the Cortex-Debug extension (if not done through OpenOCD) and for providing the Embedded Tools extension with register description `.SVD` files. [clangd](https://marketplace.visualstudio.com/items?itemName=llvm-vs-code-extensions.vscode-clangd) and clang-format are highly recommended.
