Esp8266 MicroPython中使用轮询的非阻塞服务器套接字问题
我正在尝试组装一个简单的温度计，它可以提供OLED显示屏上的温度，也可以通过使用MicroPython的ESP8266上的http请求提供温度 轮询器对象用于防止websocket阻塞环路，以便更新测量和OLED显示Esp8266 MicroPython中使用轮询的非阻塞服务器套接字问题,esp8266,micropython,usocket,Esp8266,Micropython,Usocket,我正在尝试组装一个简单的温度计，它可以提供OLED显示屏上的温度，也可以通过使用MicroPython的ESP8266上的http请求提供温度 轮询器对象用于防止websocket阻塞环路，以便更新测量和OLED显示 #CREATE SOCKET serverSocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) serverSocket.bind(('', 80)) serverSocket.listen(5) #REGISTER
