Pairing the Chromecast Remote

To pair the Chromecast Remote with the dongle:

1. Set the remote's BLE MAC address in main.c.
   Locate the line where the MAC address is defined and replace it with your remote's actual address.

2. Plug the dongle into the host device (e.g., PC or Raspberry Pi) and wait for it to boot.

3. Put the remote into pairing mode by holding Home + Back simultaneously until the LED on the remote becomes white.

⚠️ Important: The MAC address must be correctly set in main.c before attempting to pair.

Using the IR Buttons with Your TV

To make the IR buttons on the Chromecast Remote control your TV:

1. Extract the IR payloads for your specific TV model.
2. Insert the payloads into the appropriate section in main.c.
3. Once added, the firmware will allow you to switch the IR buttons between:
   • Controlling the host device via USB HID
   • Controlling the TV via infrared (IR)

To toggle between IR and USB HID mode, press the "BOOT" button on the dongle.

Customizing Button Mappings (USB HID)

To change how the Chromecast Remote buttons behave on the host device:

• Edit the remote_map_windows_hid array in main.c.

This array maps Chromecast Remote buttons to standard USB HID keycodes. Modify it to customize what each button does.
