Using a WebUSB or WebSerial device:

After connecting a WebUSB or WebSerial device, you can continue to the Gallery Page or Home Page now.
The USB-Symbol will pulse as soon as data is being received.
You can also access these options via the USB-Symbol in the navigation and the Settings Page.

Note: WebUSB and Web Serial are similar but not the same:

• While Web Serial has access to a regular COM-port and does not require special devices, the feature is not available on mobile devices.
• WebUSB requires certain microcontrollers where the processor has direct access to the USB interface (e.g. an Arduino Leonardo). See webusb for arduino on GitHub for more information.

Supported Projects

This gallery web app currently supports two specific serial devices dedicated to the GameBoy Camera:

• Receiving tiledata and captured packages printed from a physical GameBoy through the Arduino Gameboy Printer Emulator
• Sending tiledata to be printed on a physical GameBoy Printer through the Super Printer Interface

Recommended Devices (microcontrollers)

Most generic Arduinos (e.g. "Arduino Nano") should work without problems if you're working on a desktop PC.
Being able to communicate with a serial device on Android phones as well, requires a device programmed with WebUSB enabled (e.g. an "Arduino Leonardo" - aka "Arduino Pro Micro").
Neither WebUSB nor WebSerial is available when you're using Firefox or any iOS device.
