Product features:
1. The display device is a 4-digit common anode red digital tube.
2. The digital tube has 8 levels of adjustable grayscale.
3. The control interface level can be 5V or 3.3V.
4. 4 M2 screw positioning holes for easy installation.
Control interface: There are a total of 4 pins (GND, VCC, DIO, CLK), with GND being ground,
VCC is the power supply, DIO is the data input/output pin, and CLK is the clock signal pin.
Digital tube: A 0.36-inch digital tube with a score point and 4 shared anodes, highlighted in red.
Positioning holes: 4 M2 screw positioning holes with a diameter of 2.2mm, making it easy to install the module
Implement module to module combination.
Experimental Introduction:
Experimental equipment
1. 1 Arduino compatible motherboard Catduino (for those unfamiliar with open-source hardware, you can use it)
Understand as Atmega328P microcontroller development board and a mini USB cable.
2. 1 4-digit digital display module.
3. Four male to female DuPont wires are used to connect the control connectors of the module to the Catduino development board.
experimental procedure
Connect the 4-digit digital display module to Catduino using 4 male to female DuPont wires,
As shown in the table below:
Connection line GND: Black line 4-digit digital display module: GND
Connection line 5V: Red line 4-digit digital display module: VCC
Connection line D2: yellow line 4-digit digital display module: DIO
Connection line D3: white line 4-digit digital display module: CLK
① Applicable package Digital Tube for Arduino 1.0+, if libraries
There is no TimerOnew_v9 library in the directory yet, and the program needs to be downloaded from the cloud drive
Extract the library and directly extract it In the. arduino-1.0 libraries directory.
② Connect Catduino using mini USB. If this is the first time using the motherboard,
The USB to serial port driver can be found in the drivers directory of Arduino’s IDE
Drivers。
③ Reopen the Arduino IDE, click the Open button on the toolbar, and open Digi
Number Flow routine in tal Tube.
④ Select the serial port and board name, click the burn button to burn. This routine can
Flow 16 characters from 0 to 9, A, B, C, D, E, F, etc. from right to left.
⑤ The function for adjusting the grayscale display of the digital tube is the set() function in class TM1637, and the output is
The input parameter ranges from 0 to 7, and the larger the number, the higher the brightness.
