5. Операција
To operate the display module, you will need to install the necessary libraries in your Arduino IDE (or equivalent development environment for other MCUs). DSD TECH provides sample code to facilitate quick setup and usage.
5.1 Required Libraries
For Arduino, install the Adafruit ST7735 and Adafruit GFX libraries. These can typically be found and installed via the Arduino IDE's Library Manager.
5.2 Сampле Цоде
DSD TECH offers sample code that allows you to get the LCD screen operational quickly, often within minutes. Refer to the official DSD TECH support resources for the latest sample code and detailed instructions.

6. Одржавање
The DSD TECH 1.8 Inch TFT LCD Display Module requires minimal maintenance. Keep the module clean and free from dust and moisture. Avoid applying excessive force to the screen or connections.
- Модул чувајте на сувом и хладном месту када се не користи.
- Clean the screen gently with a soft, dry cloth. Do not use harsh chemicals.
- Ensure all connections are secure but not overtightened.
КСНУМКС. Решавање проблема
- Екран је замагљен или нечитљив: Ensure the module is powered with 5V. While it can function at 3.3V, a 5V supply often results in a brighter and clearer display. If using a 3.3V MCU, consider using a level shifter for signal lines while powering the display with 5V.
- Нема излаза на екран:
- Verify all wiring connections are correct according to the pinout and your MCU's specifications.
- Check that the required libraries (e.g., Adafruit ST7735, Adafruit GFX) are correctly installed in your development environment.
- Confirm that the pin definitions in your code match the physical connections to your MCU.
- Ensure the MCU is powered on and the code is successfully uploaded.
- Incorrect colors or distorted display: Double-check the initialization code for the ST7735S driver and ensure the correct display type is selected in the library.
