- Update esp32_lib_manager.py to dynamically set library extensions based on the platform (Linux, Windows, macOS).
- Update submodule references for qemu-lcgamboa and wokwi-elements.
- Add documentation on ESP32 Arduino runtime crashes related to cache disable during WiFi/BT initialization.
- Introduce regression tests for the ESP32-CAM blink issue, ensuring the user sketch matches the reported problem.
- Implement an IRAM-safe blink sketch to confirm the regression is due to the Arduino runtime.
- Create a comprehensive test suite to cover various layers of the simulation and compilation process.
- Introduced SVG layout dimensions for Phase 1 (B/W mono) and Phase 2 (colour) ePaper panels, detailing active areas, bezels, and pin layouts.
- Developed a phased emulation plan outlining the architecture and deliverables for different panel types, including SSD168x and UC81xx.
- Created a canonical "Hello, World!" sketch for the 1.54" ePaper panel, ensuring compatibility across ESP32, Raspberry Pi Pico, and Arduino Uno.
- Implemented a pure Python SSD168x decoder to validate SPI command sets and framebuffers against specifications.
- Added tests for compiling the hello-world sketch across supported boards and for the SSD168x protocol to ensure correct framebuffer behavior.
- Implemented handshake tests to validate initial bus state and register responses.
- Created end-to-end tests for Pico W LED blinking using MicroPython firmware.
- Added SDPCM framing tests to ensure proper encoding and decoding of control frames.
- Developed IOCTL tests to verify command responses and state changes in the emulator.
- Established a full lifecycle test for WiFi operations, including scanning, connecting, and packet handling.
- Introduced TypeScript configuration for test files to ensure compatibility and strict type checking.

- Introduced `_lib.py` containing shared validators for board support and static source analysis for MicroPython projects.
- Added `conftest.py` to configure pytest for the test suite, simplifying import paths.
- Created `NOT_SUPPORTED.md` files for two projects indicating they cannot be emulated in Velxio due to lack of source code.
- Implemented unit tests for the unsupported projects to verify the presence of the NOT_SUPPORTED marker and source preservation.
Docker multi-arch:
- Dockerfile downloads arch-specific QEMU .so via TARGETARCH
- docker-publish.yml adds setup-qemu-action and platforms: linux/amd64,linux/arm64
- qemu-lcgamboa submodule updated (matrix build for both architectures)
LED fix:
- LEDs now require cathode wired to GND (or LOW GPIO) to light up
- Previously LEDs turned on with anode HIGH regardless of cathode connection
- Updated tests to verify anode+cathode behavior
- Added detailed logging for GPIO changes, system events, and errors in simulation websocket.
- Improved ESP32 firmware handling by merging individual binaries into a single 4MB flash image.
- Updated ESP32 bridge to handle serial output and GPIO changes with appropriate logging.
- Introduced integration test for ESP32 emulation, covering compilation, WebSocket connection, and event handling.
- Enhanced examples to include ESP32 projects and updated the examples gallery to reflect new board types.
- Refactored simulator store to manage ESP32 bridge and simulator instances more effectively.
- Updated requirements to include esptool for ESP32 firmware management.
- Added SimulatorCanvas component for rendering the simulator interface.
- Integrated Wokwi components (Arduino, LED, Resistor, Pushbutton, Potentiometer) into the simulator.
- Created PinManager to handle pin state changes and notifications.
- Developed AVRSimulator class for emulating Arduino Uno functionality.
- Implemented hex file loading and compilation service.
- Added CSS styles for the simulator interface.
- Established Zustand stores for managing editor and simulator states.
- Created utility functions for parsing Intel HEX format.
- Set up Vite configuration for the frontend project.
- Added batch scripts for starting backend and frontend servers, and updating Wokwi libraries.
