This section outlines the basic steps for connecting and preparing your DIYmall 0.96 Inch Blue OLED Module for use with a microcontroller.

3.1 Wiring Connections (Arduino Exampле)

The OLED module communicates via I2C (also known as IIC), requiring four connections:

• VCC: Электр менен камсыздоо (3.3V-5V)
• GND: Жер
• SCL: Serial Clock Line (I2C Clock)
• SDA: Serial Data Line (I2C Data)

For an Arduino UNO, typical connections are:

• OLED VCC to Arduino 5V (red wire)
• OLED GND to Arduino GND (black wire)
• OLED SCL to Arduino A5 (white wire)
• OLED SDA to Arduino A4 (yellow wire)

3.2 I2C Address Configuration

The I2C address of the module can be changed if necessary. Refer to the product's third picture for details on modifying the IIC address by adjusting a resistor.

3.3 Library Installation (Arduino IDE)

To use the OLED module with Arduino, you will need to install the appropriate libraries. The Adafruit SSD1306 library is commonly used. Ensure you also have the Adafruit GFX library installed as it is a dependency.

Кадамдар:

1. Arduino IDE ачыңыз.
2. барыңыз Эскиз > Китепкананы кошуу > Китепканаларды башкаруу...
3. Издөө "SSD1306" and install the "Adafruit SSD1306" library.
4. Издөө "GFX" and install the "Adafruit GFX Library".
5. For clock functionality with ESP32, you may also need the "RTClib" library.

For detailed instructions on library installation and code examples, refer to the following video:

Once the module is wired and libraries are installed, you can upload example code to test its functionality and begin your projects.

4.1 Basic Display Functionality

The Adafruit SSD1306 library includes examples that demonstrate various display functions such as drawing shapes, text, and bitmaps. These examples are a good starting point to verify your setup.

4.2 Using with ESP32 and Clock Module

The OLED module can be combined with an ESP32 development board and a DS3231 Real-Time Clock (RTC) module to create projects requiring time display. Ensure correct wiring between the ESP32, RTC, and OLED module.

5. Техникалык тейлөө

The DIYmall 0.96 Inch Blue OLED Module is a robust component, but proper handling and care will ensure its longevity and optimal performance.

• Колдонуу: Avoid applying excessive pressure to the display surface. Handle the module by its edges to prevent damage to the screen or circuit board.
• Тазалоо: If necessary, gently clean the display surface with a soft, dry, lint-free cloth. Do not use abrasive cleaners or solvents.
• Сактагыч: Модулду кургак, антистатикалык чөйрөдө, түз күн нурунан жана өтө жогорку температурадан алыс сактаңыз.
• Электр камсыздоо: Ар дайым электр менен камсыздоонун көлөмүн текшериңизtage is within the specified 3.3V-5V DC range to prevent damage.

6. Кыйынчылыктарды

If you encounter issues with your OLED module, consider the following troubleshooting steps:

• Дисплей күйбөйт:
  • Verify all wiring connections (VCC, GND, SDA, SCL) are correct and secure.
  • электр менен жабдууну камсыз кылуу voltage 3.3V-5V диапазонунда.
  • Check if the microcontroller is powered on and running the code.
• Incorrect Display Output or No Output:
  • I2C дареги: The default I2C address for the SSD1306 is often 0x3C or 0x3D. If your code uses 0x3D and the display is not working, try changing it to 0x3C in your code (e.g., display.begin(SSD1306_SWITCHCAPVCC, 0x3C);). Refer to Image 3.2 for physical address modification if needed.
  • Library Issues: Confirm that the Adafruit SSD1306 and Adafruit GFX libraries are correctly installed and updated in your Arduino IDE.
  • Код каталары: Review your code for any syntax errors or logical issues. Use the Arduino IDE's serial monitor to check for debug messages.
  • Pin дайындоолор: Double-check that the SDA and SCL pins in your code match the physical pins you've connected on your microcontroller.
• Жаркылдаган дисплей:
  • Туруктуу электр менен жабдууну камсыз кылуу.
  • Бош байланыштарды текшериңиз.
