Detailed programming guides and examples can be found on the official goodisplay webсайт.

6. Техникалык тейлөө

To ensure the longevity and optimal performance of your development kit:

• Сактагыч: Store the kit in a dry, dust-free environment, away from direct sunlight and extreme temperatures.
• Тазалоо: Use a soft, dry cloth to clean the boards. Avoid using liquids or abrasive cleaners.
• Колдонуу: Handle the boards by their edges to prevent damage to components and to avoid electrostatic discharge.
• Күч: Always disconnect power before making or changing hardware connections.

7. Кыйынчылыктарды

If you encounter issues with your development kit, consider the following common solutions:

• Дисплей чыгышы жок:
  • Check all cable connections, especially the FPC cable to the e-paper display and the connection between the ESP32-L and DESPI-C73 boards.
  • Ensure the Type-C power cable is securely connected and providing 5V power.
  • Verify that the correct drivers are installed on your computer and that the development environment is properly configured.
  • Confirm that the e-paper display is compatible with the DESPI-C73 board and the ESP32-L kit.
• Программалоо каталары:
  • Double-check your code for syntax errors and logical flaws.
  • Ensure you have selected the correct board and port in your IDE.
  • Consult the sample code and documentation on the goodisplay webжетекчилик үчүн сайт.
• Unresponsive Board:
  • Try pressing the Reset button on the ESP32-L board.
  • Электр менен камсыздоону ажыратып, кайра туташтырыңыз.

8. Колдонуучунун кеңештери

• Шайкештикти текшерүү: Always ensure that your specific e-paper display model is compatible with this development kit. While designed for SPI e-paper displays, especially 7.3-inch models, verifying compatibility with other display types is crucial for successful integration.
• Энергияны башкаруу: E-paper displays consume very little power once an image is displayed. Optimize your code to put the ESP32-L into low-power modes when the display is static to maximize battery life in portable applications.
