"MAX7219 digital tube display control module MAX7219 is an integrated serial input/output common-cathode display driver. It connects a microprocessor and an 8-digit 7-segment digital LED display. It can also connect to a bar graph display or 64 independent LEDs. It includes an on-chip B-type BCD encoder, multiple scanning loops, segment word drivers, and an 8*8 static RAM to store each data. Only one external register is used to set the segment current of each LED. A convenient four-wire serial interface can be connected to all general-purpose microprocessors. Each data can be addressed without rewriting all the displays when updating. MAX7219 also allows users to select encoding or not encoding for each data. The entire device includes a 150μA low-power shutdown mode, analog and digital brightness control, a scan limit register allowing users to display 1-8 bits of data, and a detection mode that allows all LEDs to emit light. Only need 3 IO ports to drive 8-bit digital tube! No flicker when the digital tube displays! Support cascading! The display effect is shown in the figure below: The digital tube and the PCB board are connected by 2.54mm pitch round hole pin headers, which can easily replace the digital tube! The four corners of the PCB board are fixed with copper studs, which can effectively prevent accidents such as short circuits. The digital tube is a 0.36 inch 4-in-one common cathode digital tube This module is compatible with 5V/3.3V single chip microcomputer (51/AVR/STM32...) Wiring instructions (take the provided program as an example, you can connect any IO port, just modify the port definition in the program): VCC→5V GND→GND DIN →P00 CS →P01 CLK→P02 Precautions: 1. Don't connect VCC and GND reversely, so as not to burn the chip 2.51 The P0 port of the microcontroller needs to be connected to a pull-up resistor. If your microcontroller is not connected to a pull-up resistor, you can connect the data line to other po
