A VS Code extension for one-click firmware flashing with pyOCD. Auto-discovers firmware files (.elf, .hex, etc.), provides target selection, and flashes with a single click.
Features
Status bar ?Flash button for one-click flashing.
Auto-detects firmware files by configured extensions (default: .elf, .hex) with priority order. When multiple formats exist for the same base name, only the highest-priority one is shown.
Prefers common build folders (build/, out/, Debug/, Release/, bin/).
Requirements
pyocd must be installed and on PATH: pip install pyocd
Python 3 recommended.
Usage
Run PyOCD: Select Target to choose your board; or just click Flash and pick when prompted.
Build your project to produce a firmware file (e.g. .elf, .hex).
Click the ?Flash status bar button or run PyOCD: Flash, pick the firmware file, done.
