一.功能介绍：

1.可以固定显示想显示的内容
2.点阵屏幕在无指令的时候3秒换一次内容
3.可以通过云量app进行内容更改

二.芯片介绍：

MAX7219/MAX7221是一种集成化的串行输入/输出共阴极显示驱动器,它连接微处理器
与8位数字的7段数字LED显示，也可以连接条线图显示器或者64个独立的LED。其上包括一
个片上的B型BCD编码器、多路扫描回路，段字驱动器，而且还有一个8*8的静态RAM用来存
储每一个数据。只有一个外部寄存器用来设置各个LED的段电流。MAX7221与SPI™、QSPI™
以及 MICROWIRE™相兼容，同时它有限制回转电流的段驱动来减少EMI（电磁干扰）。
一个方便的四线串行接口可以联接所有通用的微处理器。每个数据可以寻址在更新时不需
要改写所有的显示。MAX7219/MAX7221同样允许用户对每一个数据选择编码或者不编码。
整个设备包含一个150μA的低功耗关闭模式，模拟和数字亮度控制，一个扫描限制寄存
器允许用户显示1-8位数据，还有一个让所有LED发光的检测模式。
在应用时要求3V的操作电压或segment blinking，可以查阅MAX6951数据资料。

三.实现原理：

我使用的控制方法跟网上流传的有一点不一样，可能很多人不是很懂我的这种驱动方法，
底层驱动我是使用的是<LedControl.h>这个库文件，因为这个库文件最大支持串联个数好像是12个还是多少个，我们这里使用了16个8*8的点阵屏幕，所以我就改了一下方法，使用了两路同时驱动的方法
上半屏我用8个max7219驱动下半屏在用另外8个就可以了，只是这样就用掉了6个io口。
实现app远程控制的原理更简单了，我们只需要使用mqtt通信协议就可以了，当然mqtt可以使用免费的也可以自己搭建一个，我这里是我自己搭建的一个mqtt服务器。
.
app部分：开发app有很多开发平台，而我这里选择的是一个中文的一个开发平台E4A，可以适合不会java的人，用户只需要提前定义好固定内容就可以，然后通过mqtt发送给单片机。
.
单片机部分：只需要使用mqtt通信协议接收订阅的主题消息就可以了，我们这里定义的比较简单，当主题消息内容为1时显示什么，为2就显示什么，就这么简单
接线：
上半屏：
DIN = D0
CS1 = D1
CLK = D2
下半屏：
DIN = D7
CS1 = D6
CLK = D5

在这里插入图片描述
下半屏同方法

四.代码部分：

#include <ESP8266WiFi.h>
#include <PubSubClient.h>
#include <Ticker.h>
#include <LedControl.h>int DIN1 = D0;
int CS1 =  D1;
int CLK1 = D2;
int DIN = D7;
int CS =  D6;
int CLK = D5;LedControl LC1 = LedControl(DIN,CLK,CS,8);
LedControl LC2 = LedControl(DIN1,CLK1,CS1,8);// 设置wifi接入信息(请根据您的WiFi信息进行修改)
const char* ssid = "H3C";  //WiFi名
const char* passwor密码d = "";//密码，如果没密码就不写
const char* mqttServer = "192.168.1.1";//mqtt服务器IP
// 如以上MQTT服务器无法正常连接，请前往以下页面寻找解决方案

PubSubClient mqttClient(wifiClient);int count,jsq;    // Ticker计数用变量
