Par19_控件数据同步演示
<p>[TOC]</p>
<h1>功能描述</h1>
<p>数据关联，用不同形式来呈现同一个控件数据。</p>
<h4>接线方法</h4>
<p>与Arduino控制器进行连接，RX-TX,GND-GND（用到了RX和TX串口）。</p>
<h4>实现功能</h4>
<p>将不同界面里不同控件的数据进行关联同步，只需给相关的控件中的其中一个设置数据便可同步更新数据显示。</p>
<h4>操作示例</h4>
<p>本例将在part13的基础上进行修改
1.打开part13的资源配置文件。
2.进入界面0，将四个数值控件复制到界面1，复制后的id号分别是107，108，109，110
3.打开控件107的配置对话框，在最下方点击选择数据关联控件id号。与100控件关联，108与101关联。109与102关联，110与同界面的109关联。
关联操作如图：
