MODBUS是一种广泛使用的工业通信协议,它允许通过串行线路在不同设备之间进行通信和数据交换。RS485模块是一个在ESP32上实现MODBUS协议的硬件。在本教程中,我们将使用RS485模块在ESP32开发板上创建一个MODBUS主机和从机设备,并实现与MODBUS主机的通信。 一、实验效果 多个Modbus(Server)从机设备与一个Modbus主机(Client...
为了方便展示,本demo中实现的socket tcp client所使用的recv()/send()是默认的阻塞模式,因此app_socket_client_connect()在成功连接server后,还需要创建两个任务app_socket_client_recv_task和app_socket_client_send_task。前者阻塞接收server发来的数据;后者等待队列client_send_queue中的数据,有则发送: //判断是...
先可以在局域网内测试,把PC当做Serve(需要在PC上写个服务端程序,反正是测试嘛怎么简单怎么来那就用python随便写几行),ESP32当做Client。ESP32通过UDP把数据先发送给Serve,Serve只做转发把收到的数据再发送给Client Client收到数据后直接通过I2S写入功放 至此就可以通过喇叭将从Mic中读到数据播放出来。所以这里创建了...

14_WIFI_TCP_ServerProgram Description This routine allows the ESP32-S3-GEEK to operate in Wi-Fi STA mode. After connecting to a hotspot created by a PC, it creates a TCP Server. The PC then creates a TCP Client to access the ESP32-S3-GEEK, establishing TCP communication. The GEEK ...
