-serialPort = serialport(portID,115200,"Timeout",1000,Tag,'portMercury'); Both return the error: 'Tag' is not a recognized parameter. When you instantiate the object, it also does not seem to contain any parameters called Tag. Is this a MATLAB 2024 thing? I'm on ...
% 打开串口 s = serial(port, baudRate, dataBits, stopBits, parity); % 配置串口超时时间(可选) s.Timeout = 10; % 单位为秒,设置为读取数据的超时时间 % 打开串口(如果之前没有打开) fopen(s); 3. 编写循环以持续从串口读取数据 使用fread或fgets函数在循环中持续读取串口数据。这里以fread为例,它...
