• 小心操作模組，防止靜電放電 (ESD) 損壞。
• Verify all connections before applying power. Incorrect wiring can lead to component failure.
• This product is intended for hobbyist and educational use. It is not designed for critical applications where failure could result in injury or significant damage.

3. 包裝內容

The diymore TM1637 4-Digit 7-Segment LED Display Module package typically includes:

• TM1637 4-Digit 7-Segment LED Display Module (quantity as purchased, e.g., 5 units)
• Right-angle male header pins (for connection)

4. 產品結束view

The diymore TM1637 module features a 0.56-inch 4-digit 7-segment LED display driven by a TM1637 controller chip. It is designed for easy integration into microcontroller projects, requiring only two digital I/O pins for communication (CLK and DIO). The module supports 8 levels of brightness adjustment for the digital tube.

6. 設定

To set up the TM1637 LED Display Module, follow these steps:

1. 建立聯繫： Solder the provided header pins to the module if not already attached. Ensure a secure connection.
2. 辨識引腳： The module has four pins:
   • VCC (5V): Connect to your microcontroller's 5V power supply.
   • 地線： Connect to your microcontroller's ground.
   • 時鐘： Connect to a digital output pin on your microcontroller (Clock pin).
   • 迪奧： Connect to another digital output pin on your microcontroller (Data I/O pin).
3. Connect to Microcontroller: Wire the module to your microcontroller (e.g., Arduino, ESP32) according to the pin identification.
4. 安裝庫： For Arduino IDE users, install the TM1637.h library. This can typically be done via the Arduino IDE's Library Manager (Sketch > Include Library > Manage Libraries...). 搜尋 "TM1637" and install the appropriate library.

7. 操作說明

Once the module is wired and the library is installed, you can begin programming your microcontroller to control the display.

Basic Programming Steps (using Arduino and TM1637.h library):

1. Include Library: At the beginning of your sketch, include the library: #include <TM1637Display.h>
2. Define Pins: Define the CLK and DIO pins you connected: #define CLK 2 （前任ample pin) #define DIO 3 （前任ample pin)
3. Initialize Display: Create a TM1637Display object: TM1637Display display(CLK, DIO);
4. 設置亮度： 在你的 setup() function, set the display brightness (0-7): display.setBrightness(0x0f); (0x0f is maximum brightness, 0x00 is off)
5. Display Numbers: 使用 display.showNumberDec(value, dots, leading_zeros, length, position); to display decimal numbers. For examp樂， display.showNumberDec(1234, false, false, 4, 0); will show "1234".
6. Display Time (with colon): To display time, you can use the colon feature. The colon is often controlled by a specific bitmask or a parameter in the display function. Refer to the library's examples for precise implementation. For examp樂， display.showNumberDecEx(1234, 0b01000000, false, 4, 0); might activate the colon.

Consult the specific TM1637.h library documentation and examples for advanced functions and detailed usage.

8、維護保養

• 保持模組清潔，無灰塵和碎屑。清潔時請使用柔軟的乾布。
• 避免將模組暴露在極端溫度或濕度下。
• Regularly check solder joints and connections for any signs of corrosion or loosening, especially in projects subject to vibration.
• Store the module in an anti-static bag when not in use.

9。 故障排除

Display is blank or not lighting up:

• Check power connections (5V and GND).
• Verify CLK and DIO connections to the microcontroller.
• 確保 TM1637.h library is correctly installed and initialized in your code.
• Confirm the brightness level is set appropriately (not 0x00).

Display is flickering:

• This can sometimes occur if the display update function is not called frequently enough or if there are timing issues in your code. Ensure the display update function is called consistently.
• Some modules may exhibit slight flickering if not continuously refreshed. A common workaround is to repeatedly call the segment setting function at a rate of 40-60 times per second.

Decimal points do not work:

• Some TM1637 modules, particularly those designed as clock displays, may have the decimal points physically unconnected or wired to the colon segment.
• 這 TM1637.h library typically controls the colon (double dots) but may not support individual decimal points for all segments. Review the library's specific functions and examples for decimal point control.
• If decimal points are critical for your application, verify the module's specific wiring diagram or consider an alternative display module.

Incorrect characters or segments displayed:

• Double-check your code for correct segment mapping or number conversion functions.
• Ensure the correct library functions are being used for the desired output.
