3. การตั้งค่า

3.1. การเชื่อมต่อฮาร์ดแวร์

The 1.5-inch Transparent OLED Display module can be connected to various microcontrollers and development boards such as Raspberry Pi, Arduino, and STM32. Ensure proper pin mapping according to the selected communication mode (SPI or I2C).

• แหล่งจ่ายไฟ: Connect VCC to 3.3V or 5V (depending on your board's logic level) and GND to ground.
• Communication Mode Selection: The module supports both SPI and I2C. The communication mode is typically selected by soldering resistors on the back of the module. Refer to the module's datasheet for specific resistor configurations.
• SPI Connection (4-wire): Connect DIN (Data In), CLK (Clock), CS (Chip Select), and DC (Data/Command) pins to the corresponding SPI pins on your microcontroller.
• การเชื่อมต่อ I2C: Connect SDA (Serial Data) and SCL (Serial Clock) pins to the corresponding I2C pins on your microcontroller.
• Reset Pin (RST): Connect the RST pin to a GPIO pin on your microcontroller for software reset control.

4. คู่มือการใช้งาน

4.1. การตั้งค่าซอฟต์แวร์

To operate the transparent OLED display, you will need to use appropriate libraries and code examples for your chosen microcontroller platform. Comprehensive supporting materials, tutorials, and technical support are typically provided by the manufacturer to assist with software integration.

• อาร์ดูอิโน่: Utilize the SSD1309 library for Arduino IDE. Ensure the correct communication mode (SPI or I2C) is configured in the library or your sketch.
• ราสเบอร์รี่ Pi: Use Python libraries such as luma.oled or similar, which support the SSD1309 driver. Configure the SPI or I2C interface in the Raspberry Pi's settings.
• สตม32: Refer to the manufacturer's provided examples or community resources for STM32 HAL or LL library implementations for SSD1309.

4.2. Displaying Content

Once the hardware and software are correctly configured, you can program the display to show text, graphics, or sensor data. The 128x64 resolution allows for clear display of small images and alphanumeric characters. The transparent nature of the screen enables unique applications where information can be overlaid on a real-world view.

5. การบำรุงรักษา

5.1. การดูแลและการจัดการ

• Avoid applying excessive pressure to the display surface.
• Handle the flexible connector cable with care to prevent damage.
• Store the module in a dry, anti-static environment when not in use.
• Protect the display from direct sunlight and extreme temperatures.

5.2. การทำความสะอาด

To clean the transparent OLED display, gently wipe the surface with a soft, lint-free cloth. For stubborn smudges, lightly dampen the cloth with distilled water or a specialized screen cleaner. Avoid using harsh chemicals, abrasive materials, or excessive moisture, as these can damage the display.

6 การแก้ไขปัญหา

• ไม่มีจอแสดงผล:
  • Check all power connections (VCC, GND) to ensure they are secure and providing the correct voltage.
  • Verify that the communication pins (SPI/I2C) are correctly wired and connected to the microcontroller.
  • Ensure the communication mode (SPI or I2C) is correctly selected via the onboard resistors or software configuration.
  • Confirm that the display library is correctly installed and initialized in your code.
  • Check the RST pin connection and ensure it is being properly toggled or held high/low as required by the driver IC.
• Garbled or Incorrect Display:
  • Verify that the correct display resolution (128x64) is set in your software.
  • Check for any loose connections in the data lines.
  • Ensure the correct driver IC (LD7318) is specified in your software library.
  • If using SPI, confirm the correct SPI mode (e.g., CPOL, CPHA) is configured.
• จอแสดงผลกะพริบ:
  • Ensure a stable power supply is provided to the module.
  • Check for electromagnetic interference (EMI) from nearby components.
  • Adjust the refresh rate or contrast settings in your software, if available.
