4.1 E-Paper Display Characteristics

The 4.7-inch E-Paper display has specific characteristics:

• Due to the flexible nature of the screen, small bubbles may be present in the corners during fitting. This is a normal manufacturing characteristic.
• This version of the E-Paper screen may exhibit a slight yellowish tint.
• Partial refresh of the screen for extended periods can result in residual images (ghosting).

5. Asennus

To begin using your LILYGO T5-4.7-S3 board, follow these setup steps:

1. Liitä virta: Connect the board to a computer using a USB-C cable. The board will power on.
2. Initial Firmware Check: The board typically comes with factory test firmware. If the screen displays content, the hardware is likely functioning correctly.
3. Asenna ajurit: Ensure your computer has the necessary USB-to-serial drivers for ESP32-S3 devices. These are usually automatically installed or can be found on the Espressif websivusto.
4. Valmistele kehitysympäristö: Install your preferred programming environment (Arduino IDE, VS Code with PlatformIO, or MicroPython). Refer to the official LILYGO GitHub repository for detailed setup instructions and examples: github.com/Xinyuan-LilyGO/LilyGo-EPD47/tree/esp32s3.

5.1 Laiteohjelmiston päivittäminen

To upload new firmware or examples, you will need to put the board into DFU (Device Firmware Upgrade) mode:

1. Connect the board to your computer via the USB-C cable.
2. Paina ja pidä painettuna BOOT -painiketta.
3. Samalla kun pidät edelleen BOOT button, briefly press the RST -painiketta.
4. Vapauta RST -painiketta.
5. Vapauta BOOT -painiketta.
6. The board is now in DFU mode and ready for firmware upload via your chosen development environment.

6. Käyttöohjeet

Once firmware is loaded, the operation of the LILYGO T5-4.7-S3 will depend on the specific application programmed onto it. Generally, interaction will be via the 4.7-inch touchscreen.

• Kosketusnäyttö: Navigate menus and interact with applications by tapping or swiping on the capacitive touchscreen.
• Painikkeet: The board may include physical buttons (e.g., RST, BOOT) that can be programmed for specific functions within your application.
• SD-kortti: Insert a microSD card into the slot for data storage or loading assets for your applications, such as maps or images.
• USB-C: Use the USB-C port for power, data transfer, and debugging.

6.1 Esimample Application: Mesh Networking

The ESP32-S3's wireless capabilities can be utilized for mesh networking, allowing devices to communicate without traditional internet infrastructure. This is particularly useful in off-grid or emergency situations.
