The MAX7219 is an integrated serial input / output common cathode display driver that connects a microprocessor with an 8-digit 7-segment digital LED display. It can also connect a bar graph display or 64 separate LEDs. It includes an on-chip B-type BCD encoder, multi-scan circuitry, segment word drivers, and an 8 * 8 static RAM for storing each data. Only one external register is used to set the segment current for each LED.
A convenient four-wire serial interface can interface with all common microprocessors. Each data can be addressed without having to rewrite all the displays when updating. The MAX7219 also allows the user to select or not to encode each data item.
The entire device includes a 150μA low-power shutdown e, analog and digital brightness control, a scan limit register that allows the user to display 1-8 bits of data, and a detection e that enables all LEDs to emit light.
Only three IO ports can drive a dot matrix! No blinking dot matrix display! Support cascade!
A single ule can drive an 8 * 8 common-negative lattice
ule working voltage: 5V
With 64 fixed screw holes, aperture 3mm
ule with input and output interfaces, support for multiple ules cascade
Wiring instructions:
1. The left side of the ule is the input port, the right is the output port.
2. When controlling a single ule, only the input port needs to be connected to the CPU
3. When multiple ules are cascaded, the input of the first ule is connected to the CPU, the output is connected to the input of the second ule, the output of the second ule is connected to the input of the third ule, and so on. ..
Take 51 SCM as an example:
VCC → 5V
GND → GND
DIN → P2.2
CS → P2.1
CLK → P2.0
colour:white
Material:Metal + PC
ule Size: 70*65*30mm
Package Contents:
1 * LED Display uleOnly the above package content, other products are not included.
Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1
