MATLAB App Designer 代码错误针对 MCC DAQ

如何解决MATLAB App Designer 代码错误针对 MCC DAQ

我创建了一个 MATLAB 应用程序，当用户单击“开始”按钮时，它会从 MCC USB-1608FS-Plus 系列 DAQ 设备读取模拟数据。运行此应用程序会导致以下错误：

Warning: DAQSDK Warning: Ignored call to method 'stop' in state 'ReadyState'. 
Error using test/StartButtonPushed (line 54)
Timeout expired before operation Could complete.

请问，有人碰巧知道解决方案吗？这是我的代码，我在导致错误的行上方进行了注释：

properties (Access = public)
        analogData;
        analogDevice;
        startTime;
        stopButtonpressed = false;
        times = zeros(1,720*120);
end

function StartButtonPushed(app,event)
            app.stopButtonpressed = false;
            
            app.analogDevice = daq("mcc");
            addinput( app.analogDevice,"Board0","Ai0","Voltage" );
            app.analogDevice.Rate = app.RatescanssEditField.Value;
            app.analogDevice.UserData = struct("Data",[],"Count",1);
            
            % THIS LINE CAUSES AN ERROR
            app.analogData = read(app.analogDevice,seconds( app.DurationSpinner.Value ) );
            
            t0 = clock;
            app.startTime = datetime;

            while(etime(clock,t0) < app.DurationSpinner.Value) && (app.stopButtonpressed == false)
                app.times(1) = etime(clock,t0);
            end
            
            app.SavetoFileButton.Enable = true;
        end
