3.2. Development Environment Configuration

The ESP32 HMI Display supports various development environments. For Arduino IDE, follow these general steps:

1. Download and Install Arduino IDE: Obtain the latest version from the official Arduino website.
2. Install ESP32 Board Package: Within the Arduino IDE, navigate to File > Preferences. Add the ESP32 board manager URL (typically https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json) to 'Additional Boards Manager URLs'. Then, go to Tools > Board > Boards Manager, search for 'ESP32', and install the package.
3. Select Board and Port: Connect the display to your computer using the provided USB-A to Type-C cable. In Arduino IDE, select the appropriate board (e.g., 'ESP32S3 Dev Module' for 5-inch display) under Tools > Board > ESP32 Arduino. Also, select the correct COM port under Tools > Port. If the port is not recognized, you may need to install the CH340 driver.
4. Configure PSRAM and Partition Scheme: For 5-inch displays, set PSRAM to 'OPI PSRAM' and Partition Scheme to 'Huge App' (or 'Default AAB with spiffs (1.2MB APP/1.5MB SPIFFS)' if not using LVGL) under Tools.

For a visual guide on setting up the development environment, please refer to the official video tutorial:

7. Maintenance

To ensure the longevity and optimal performance of your ELECROW 5-inch ESP32 HMI Display, please adhere to the following maintenance guidelines:

• Cleaning: Use a soft, dry, anti-static cloth to clean the screen and casing. Avoid abrasive cleaners, solvents, or aerosol sprays, as these can damage the display surface or internal components.
• Handling: Handle the display with care to prevent physical damage. Avoid dropping the device or subjecting it to strong impacts.
• Storage: Store the display in a cool, dry environment away from direct sunlight, extreme temperatures, and high humidity. When not in use, it is recommended to store it in its original packaging or a protective case.
• Power: Always use the recommended power supply (5V) to prevent electrical damage. Disconnect power when not in use or during maintenance.

8. Troubleshooting

If you encounter issues with your ELECROW 5-inch ESP32 HMI Display, consider the following troubleshooting steps:

• Display Not Powering On: Ensure the USB-C cable is securely connected to both the display and a reliable power source. Verify the power source is active.
• No Display Output: Check if the display is receiving power. If using a custom program, ensure it has been successfully uploaded and is designed to initialize the display.
• Touch Screen Unresponsive: Verify that the touch screen ribbon cable is properly seated. If using a custom program, ensure the touch driver is correctly initialized in your code.
• Compilation or Upload Errors: Double-check your Arduino IDE setup, including the installed ESP32 board package version, selected board, COM port, PSRAM setting, and partition scheme. Ensure all necessary libraries are installed.
• Garbled Serial Output: Confirm that the baud rate set in your serial monitor matches the baud rate configured in your program (e.g., 9600 baud).
• Computer Not Recognizing Serial Port: Install or update the CH340 USB-to-Serial driver for your operating system.
