一.布局设计UI

1.主体：grid 2行 2列

00 下载按钮 20% 01进度条 80% （同时显示百分比）

10 11都是跨列显示日志

2.细节：百分比与进度条Value绑定。下载按钮默认获得焦点回车就能点击。日志只读等。各控件Name命名等。百分比水平垂直居中等。

（&D）快捷方式设置不了？

我想百分比后加%，绑定时如何设置？我知道用程序设置。

二、程序代码

1.生成各控件的方法

2.协议（固件下载），与我协议一致，都通用。

07首包 4字节固件长度+32字节固件MD5大写字符串

08中间包 1024字节每包，分包，分成多个中间包，最后一包发剩下(不剩就不发)

09尾包

协议框架：头1字节+APDU长度2字节+APDU内容+CRC16 2字节

APDU结构：FC +功能码一字节(07,08,09)+ 00 00 00 +DATA长度2字节+DATA内容

3.流程

开串口，准备数据等。

线程一清响应发送等信号或超时有信号且结果正确，继续发送。发送完成显结果关串口等。

线程二接收响应解析结果发信号持续接收。

4.附加功能

首次选择文件后，后续插拨设备自动批量下载。监听USB插拨。

拖放文件到界面。winForm版我做了。

5.其他数据转换等功能API

6.细节

退出应用，关闭线程，关闭串口。

再次点下载，变为停止。

日志写入文件。

下载成功或失败日志区变为绿色或红色。

支持全屏。
