4.2. General Connection Guidelines

Connect the module to your microcontroller using the SPI interface. Ensure that the VCC and GND pins are connected to the appropriate power supply (2.8V-3.3V). The SCL, SDA, RES, DC, and CS pins should be connected to digital I/O pins on your microcontroller. Refer to your microcontroller's documentation for specific SPI pin assignments.

5. Obsluha modulu

To operate the 1.44-inch TFT LCD module, you will typically need to use a software library compatible with the ST7735 controller. Many microcontrollers, such as Arduino and ESP32/ESP8266, have existing libraries that simplify the process of initializing the display and drawing graphics or text.

5.1. Inicializace

The initialization sequence for the ST7735 controller involves sending a series of commands to set up the display's internal registers, including power control, gamma correction, and frame rate. Most libraries handle this automatically.

5.2. Displaying Graphics and Text

Once initialized, you can use library functions to draw pixels, lines, rectangles, circles, and display text. The 128x128 resolution allows for basic graphical interfaces and data visualization. Remember that the module operates at 3.3V logic levels; ensure your microcontroller's I/O pins are compatible or use level shifters if necessary.

7. Údržba

To ensure the longevity and optimal performance of your TFT LCD module, follow these maintenance guidelines:

• Zacházení: Always handle the module by its edges to avoid touching the display surface or electronic components.
• Čištění: Použijte měkký hadřík bez žmolků, lehceampened with water or a specialized screen cleaner, to gently wipe the display surface. Avoid abrasive materials or harsh chemicals.
• Skladování: Store the module in a dry, dust-free environment, away from direct sunlight and extreme temperatures.
• Napájení: Zajistěte napájení objtage is within the specified range (2.8V-3.3V) to prevent damage.
• Statická elektřina: Take precautions against electrostatic discharge (ESD) when handling the module, as electronic components are sensitive to static.

8. Řešení problémů

If you encounter issues with your WINGONEER 1.44-inch TFT LCD Module, consider the following troubleshooting steps:

• Žádný displej/prázdná obrazovka:
  • Verify all power connections (VCC, GND) are correct and within the specified voltage rozsah.
  • Check all SPI data and control line connections (SCL, SDA, RES, DC, CS) for proper wiring.
  • Ensure the backlight control pin (BLK) is correctly configured or left floating if not actively controlled.
  • Confirm that the display initialization code in your software is running correctly.
• Garbled or Incorrect Display:
  • Check for correct SPI mode and clock polarity/phase settings in your software.
  • Verify that the data sent to the display matches the expected format (e.g., color depth, byte order).
  • Ensure the display orientation settings (if applicable in your library) are correct.
• Modul nereaguje:
  • Confirm that the reset pin (RES) is being toggled correctly during initialization.
  • Check for any short circuits or damaged pins on the module or connecting wires.
