"MAX7219 Led Module 8-Digit 7 Segment Digital LED Display Tube "

The MAX7219 is an integrated serial input / output co-cathode display driver that connects a microprocessor with an 8-digit 7-segment digital LED display or a bar graph display or 64 independent LEDs. Which includes an on-chip B-type BCD encoder, multi-scan circuit, segment word drive, but also a 8 * 8 static RAM used to store each data. Only one external register is used to set the segment current for each LED.

This module is compatible with 5V / 3.3V microcontroller (51 / AVR / STM32 .......)

Wiring instructions (to provide the program as an example, you can take any IO port, in the process of modifying the port can be defined):

VCC → 5V

GND → GND

DIN → P00

CS → P01

CLK → P02

Note:
1.VCC and GND do not reverse, so as not to burn the chip.
2.51 microcontroller P0 port need to pull on the resistor, if your microcontroller is not connected to the pull-up resistor, you can connect the data cable to other ports.
