8 การแก้ไขปัญหา

If you encounter issues with your development board, consider the following:

• เมนบอร์ดไม่เปิดใช้งาน:
  • Check the USB Type-C cable connection and ensure the power source is active.
  • If using a battery, ensure it is charged and properly connected to the MX1.25 header.
• หน้าจอสัมผัสไม่ตอบสนอง:
  • It is normal for touch sensitivity and accuracy to be reduced at the edge of the round touch screen.
  • Ensure your code correctly initializes and handles the CST816S touch driver.
  • Restart the board using the RESET button.
• ข้อผิดพลาดในการเขียนโปรแกรม:
  • ตรวจสอบให้แน่ใจว่าได้เลือกบอร์ดและพอร์ตที่ถูกต้องใน IDE ของคุณแล้ว
  • Ensure all necessary drivers (e.g., CH343P USB to UART chip driver) are installed.
  • Try entering download mode by holding the BOOT button while pressing RESET before uploading.
• ปัญหาการเชื่อมต่อ Wi-Fi/Bluetooth:
  • Check your code for correct Wi-Fi/Bluetooth initialization and credentials.
  • When using the development board, pay attention to the ceramic antenna area and avoid the PCB board, metal, and plastic parts covering the ceramic antenna, as this can interfere with signal.
• ปัญหาการชาร์จแบตเตอรี่:
  • The onboard high-efficiency charge/discharge power management chip ETA6096 and MX1.25 battery header are designed for a 3.7V single-cell lithium battery.
  • The current charging current is set to 1A. For different charging currents, refer to the schematic to change the R15 resistor.
