- Decoupled electrical simulation from the simulator store, ensuring SPICE is always active for accurate circuit analysis.
- Removed feature flag for electrical simulation, simplifying the state management.
- Preloaded SPICE engine at app start to eliminate latency during the first solve.
- Added comprehensive tests for MOSFET PWM LED behavior and NPN transistor switch functionality, ensuring correct current flow and response to pin states.
- Implemented diagnostics for floating input nodes in RC low-pass filter circuits, addressing singular matrix issues in SPICE simulations.
- Introduced active semiconductor metadata registry for better component management and simulation fidelity.
- Updated Vite configuration to force re-bundling of local wokwi-elements after component additions.
Implements MicroPython emulation for Raspberry Pi Pico boards running
entirely in the browser using rp2040js. Users can toggle between
Arduino C++ and MicroPython modes via a language selector dropdown.
Key changes:
- Add LanguageMode type and BOARD_SUPPORTS_MICROPYTHON to board types
- Create MicroPythonLoader.ts: UF2 firmware parser, LittleFS filesystem
builder (via littlefs-wasm), IndexedDB firmware caching
- Extend RP2040Simulator with loadMicroPython() method using USBCDC for
serial REPL instead of UART
- Add setBoardLanguageMode and loadMicroPythonProgram store actions
- Update EditorToolbar with language toggle and MicroPython compile flow
- Enhance SerialMonitor with REPL label, Ctrl+C/D support
- Bundle MicroPython v1.20.0 UF2 firmware as fallback in public/firmware/
- Update useEditorStore to create main.py default for MicroPython mode
