matlab app实现串口端口扫描

要实现串口端口扫描的MATLAB App，可以按照以下步骤进行操作：

1. 在MATLAB App Designer中创建一个新的App。

2. 在App Designer中添加一个按钮或者其他控件，用于触发串口端口扫描。

3. 在回调函数中，使用MATLAB的serial函数来扫描所有可用的串口端口。

4. 将扫描结果显示在App中的列表或者其他控件中。

下面是一个示例代码，可以实现串口端口扫描：

classdef SerialPortScanner < matlab.apps.AppBase

    % Properties that correspond to app components
    properties (Access = public)
        UIFigure              matlab.ui.Figure
        ScanButton            matlab.ui.control.Button
        PortList              matlab.ui.control.ListBox
    end

    % Callbacks that handle component events
    methods (Access = private)

        % Button pushed function: ScanButton
        function scanButtonPushed(app, event)
            % Scan for available serial ports
            ports = seriallist();
            % Display the list of available ports
            app.PortList.Items = ports;
        end
    end

    % App initialization and construction
    methods (Access = private)

        % Create UIFigure and components
        function createComponents(app)

            % Create UIFigure and set properties
            app.UIFigure = uifigure('Visible', 'off');
            app.UIFigure.Position = [100 100 640 480];
            app.UIFigure.Name = 'Serial Port Scanner';

            % Create ScanButton
            app.ScanButton = uibutton(app.UIFigure, 'push');
            app.ScanButton.ButtonPushedFcn = createCallbackFcn(app, @scanButtonPushed, true);
            app.ScanButton.Position = [270 210 100 22];
            app.ScanButton.Text = 'Scan';

            % Create PortList
            app.PortList = uilistbox(app.UIFigure);
            app.PortList.Position = [240 260 150 150];

            % Show the figure after all components are created
            app.UIFigure.Visible = 'on';
        end
    end

    % App startup and shutdown
    methods (Access = private)

        % Close request function: UIFigure
        function figureCloseRequest(app, event)
            % Delete the figure when closing
            delete(app.UIFigure);
        end
    end

    % App creation and deletion
    methods (Access = public)

        % Construct app
        function app = SerialPortScanner

            % Create UIFigure and components
            createComponents(app)

            % Register the app with App Designer
            registerApp(app, app.UIFigure)

            % Execute the startup function
            runStartupFcn(app, @startupFcn)

            % Show the figure
            if nargout == 0
                clear app
                return
            end
        end

        % Code that executes before app deletion
        function delete(app)

            % Delete UIFigure when app is deleted
            delete(app.UIFigure)
        end
    end
end

这个App包括一个按钮和一个列表控件，点击按钮可以扫描所有可用的串口端口，并将结果显示在列表中。可以根据需要对这个App进行自定义和扩展。
