4. عملیاتي لارښوونې

To operate the display module, you will typically use a compatible library for your chosen microcontroller. For Arduino, libraries such as Adafruit GFX Library and Adafruit ST7789 Library are commonly used.

4.1 Software Setup (Arduino Exampلی)

  1. کتابتونونه نصب کړئ: Open your Arduino IDE. Go to سکیچ > کتابتون شامل کړئ > کتابتونونه اداره کړئ... لټون "Adafruit GFX" and "Adafruit ST7789" and install them.
  2. Include Headers: In your Arduino sketch, include the necessary headers:
    #include <Adafruit_GFX.h>
    #include <Adafruit_ST7789.h>
  3. پنونه تعریف کړئ: Define the pins connected to the display module in your sketch. For example, using the pins from Table 2:
    #define TFT_CS    10
    #define TFT_DC 9
    #define TFT_RST 8 // Or set to -1 if you share Arduino reset pin
  4. Initialize Display: Initialize the display object in your setup function:
    Adafruit_ST7789 tft = Adafruit_ST7789(TFT_CS, TFT_DC, TFT_RST);

    void setup() {
    tft.init(240, 240); // Initialize ST7789 screen
    tft.setRotation(2); // Adjust rotation as needed
    tft.fillScreen(ST77XX_BLACK);
    tft.setTextWrap(false);
    tft.setTextColor(ST77XX_WHITE);
    tft.setTextSize(1);
    tft.setCursor(0, 0);
    tft.print("Hello, World!");
    }
  5. Drawing Functions: Use the GFX library functions to draw text, shapes, and images on the display. Refer to the Adafruit GFX library documentation for a full list of functions.

6. ستونزه حل کول

  • Display is blank or shows garbage:
    • د تارونو چک کول: Verify all connections (GND, VCC, SCL, SDA, RES, DC, CS) are secure and correctly connected to the appropriate microcontroller pins as per the wiring diagram. Pay close attention to SPI pin assignments (SCL/SCK, SDA/MOSI).
    • د بریښنا رسول: Ensure the VCC pin receives the correct voltage (typically 3.3V or 5V, depending on your MCU's logic level and the module's tolerance).
    • د کتابتون نصبول: Confirm that all necessary libraries (e.g., Adafruit GFX, Adafruit ST7789) are correctly installed in your IDE.
    • Initialization Code: Double-check your code for correct pin definitions and display initialization parameters (e.g., tft.init(240, 240)).
    • SPI vs. I2C Confusion: This module uses SPI. Ensure you are not attempting to connect it using I2C pins or I2C libraries, despite some pin labels potentially causing confusion.
  • Colors are incorrect or washed out:
    • د گردش ترتیب: غلط setRotation() might affect how colors are interpreted or displayed. Experiment with different rotation values.
    • د کتابتون نسخه: Ensure you are using up-to-date libraries.
  • Display works on one MCU (e.g., ESP32) but not another (e.g., Arduino):
    • د پن مطابقت: Verify that the SPI pins and other control pins are correctly mapped for the specific MCU you are using. Pin numbers for SPI can differ between Arduino boards (Uno, Nano, Mega) and other platforms like ESP32 or Raspberry Pi.
    • د منطق کچه: ډاډ ترلاسه کړئ حجمtage compatibility. Some MCUs operate at 3.3V logic, while others use 5V. The display module typically supports both, but incorrect voltage levels can cause issues.

7. ساتنه

The 1.54-inch TFT display module is a delicate electronic component. Follow these guidelines for proper maintenance:

  • سمبالول: Always handle the module by its edges to avoid touching the screen surface or electronic components.
  • پاکول: If necessary, gently clean the screen with a soft, lint-free cloth. Avoid abrasive materials or harsh chemical cleaners.
  • ذخیره کول: Store the module in an anti-static bag in a dry, cool environment away from direct sunlight and extreme temperatures.
