ESP-IDF Extension for VS Code
Shanghai, China
What it is
ESP-IDF Extension for VS Code lets developers create, build, flash, monitor, debug, and manage projects for Espressif chips within Visual Studio Code. Its wizard starts projects from ESP-IDF examples or configured framework templates. Builds use CMake and Ninja, and devices can be flashed over UART, DFU, or JTAG. Debugging covers live device work as well as postmortem analysis with a core dump or GDB stub. Other tools include code coverage, heap tracing, application-level tracing, binary size analysis, and an eFuse viewer. The extension can install components from the ESP Component Registry and add Arduino as an ESP-IDF component. QEMU can emulate debugging and monitor output. Documentation describes use in Docker, WSL, SSH, Dev Containers, Codespaces, and browser-based VS Code environments. It also contributes MCP servers and exposes ESP-IDF commands to language-model integrations such as Copilot. Visual Studio Code is required. The extension is free, licensed under Apache License 2.0, and supports Windows, macOS, and Linux.
