ESPJarvis依赖的第三方库文件有Adafruit SSD1306和PubSubClient,这些都可以在Arduino IDE的包管理器中进行添加和安装。 Arduino IDE的示例程序如下,读者可以根据自己的需求进行修改 #include<ESPJarvis.h>//函数定义voidShowSoftwareInfo();voidInitWifi();voidInitHardware();//***用户无线网络设置参数***//constcha...
然后使用MQTTClient_create()函数创建一个MQTT客户端,创建成功后客户端结构体将赋值给client; // 2、创建一个MQTT客户端 if ((rc = MQTTClient_create(&client, MQTT_Uri, ClientId, MQTTCLIENT_PERSISTENCE_NONE, NULL)) != MQTTCLIENT_SUCCESS) { printf("Failed to create mqtt client, return code %d\n...
举个例子:client1 首先向 broker 发送 CONNECT 数据包其中 lastWillMessage 将”offline“ 作为 payload lastWillRetain 设置为 true lastWillTopic 设置为 client1/status 连接之后 client1 再向主题发送一条 PUBLISH 消息,其 payload 为”online“ 并将其 retain flag 设置为 true。 此时 只要 client1保持连接,...

CODESYS 是一个基于 Codesys 的嵌入式操作系统,它为开发者提供了丰富的开发工具和库。在 CODESYS 中,QoS(Quality of Service)是一种用于描述网络通信服务质量的技术,它定义了网络传输过程中数据包的优先级、延迟、抖动等指标。 为了支持 QoS 功能,CODESYS 提供了一个名为 CODESYSMQTTMQTT 的客户端库。这个库允许...
笔者的树莓派4目前主要运行着NextCloud私人网盘,Home Assitant智能家居系统,Codesys 软PLC运行时和OpenPLC 软PLC运行时。为了能监控系统实时的状态,我们可以把系统的状态数据通过MQTT协议发送出去。关于MQTT的理论知识介绍可以参考如下文章 深入浅出MQTT 为此我们需要首先在树莓派上安装一个MQTT服务器Mosquitto软件负责管理这些...
