Product Description

Introduction:

MAX7219 is an integrated serial input/output CC 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 scan 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 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 to make all LEDs glow. Only 3 IO ports can drive 1 dot matrix! No flicker during dot matrix display! Support cascading!

Parameters: 1. A single module can drive an 8*8 common cathode matrix 2. Working voltage: 5V 3. Size: 12.8 * 3.2 * 1.3 cm 4. With 4 fixing screw holes, 3mm diameter 5. Module with input and output interface, support multiple module cascade

Wiring instructions: 1. The left side of the module is the input port, and the right side is the output port. 2. When controlling a single module, you only need to connect the input port to the CPU 3. When multiple modules are cascaded, the input terminal of the first module is connected to the CPU, the output terminal is connected to the input terminal of the second module, the output terminal of the second module is connected to the input terminal of the third module, and so on. .. Take 51 SCU as an example: VCC → 5V GND → GND DIN → P2.2 CS → P2.1 CLK → P2.0
