From the VS Code extension

Use MCUHex with your own firmware.

The VS Code panel shows the demo. The dashboard is where you upload your .elf, resolve symbols, connect your probe, and read live variables from your board.

Open Projects

You can create the project now. Sign-in is requested when you upload and parse your .elf.

1

Create or select a project

A project gives MCUHex a place to keep your parsed symbols and monitor state.

2

Drop your .elf file

MCUHex resolves debug symbols so you can search variables by name instead of manual addresses.

3

Connect the SDK and read values

Use the local bridge with ST-Link, J-Link or DAPLink over SWD to flash and monitor your board.

The local SDK currently ships for macOS Apple Silicon and Windows x64. If you installed MCUHex from Open VSX on Linux or a remote editor, the web dashboard still opens, but the local SDK demo will not run on that host yet.
