This module encapsulates the access for the serial port. It provides backends for Python running on Windows, Linux, BSD (possibly any POSIX compliant system), Jython and IronPython (.NET and Mono). The module named "serial" automatically selects the appropriate backend. It is released under a ...

app.a = serialport(app.SerialPortsDropDown.value,9600); 这是将Arduino连接到MATLAB的错误方式。此声明不允许我们使用Arduino函数,例如“writeDigitalPin,writePWMDutyCycle'., 正如我在评论中提到的,首先清除端口并连接串行端口仍然很重要。 最后,声明Arduino能够使用其功能的真正方法如下: app.a = arduino(app...
