在 MATLAB Online 中打开

        % To construct a serial port object:
          s1 = serial('COM1');
          s2 = serial('COM2', 'BaudRate', 1200);
        % To connect the serial port object to the serial port:
          fopen(s1)
          fopen(s2)
my_value = get(handles.my_Slider_handle,'value');
fprintf(s1,value)
