Hardware Flashing & Serial Monitor

The Web Serial Bridge (webSerialHardware.js)

OpenHW Studio uses the browser's navigator.serial API to talk directly to physical boards.

• Vendor Filtering: The DEFAULT_SERIAL_USB_FILTERS array isolates relevant microcontrollers by filtering USB Vendor IDs (e.g., Arduino 0x2341, Espressif 0x303A, Raspberry Pi 0x2E8A).
• Stream Management: Implements read/write loops using TextEncoder and TextDecoder streams to pipe data into the frontend SimulationConsole.

Firmware Flashing (useHardwareFlashing.js)

When a user wants to push their code to a physical board:

1. The frontend hits the Compiler Backend to get the compiled Hex/UF2 binary.
2. The flashFirmware hook takes over, opening the serial port at the correct hardwareBaudRate.
3. It applies the necessary hardwareResetMethod (e.g., toggling DTR/RTS for ESP32/Arduino) to push the board into bootloader mode before streaming the binary.
