• WPF项目实战布局--通用固件下载 C#

    每个作品都是产品

    C# WPF版效果：

     C# winForm版效果:

     

    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。
