RS-485标准定义了一个极为坚固和可靠的通信链路，具有高噪声抑制、宽共模范围、长传输距离、冲突保护等特性。 但一个真正牢靠的RS-485网络还有赖于合理的应用。合理的网络布局、信号通道的连续性、周全的保护措施等，在设计之初就应该有一个总体规划-RS-485 standard definition of a very robust and reliable communication links with high noise suppression, and wide common-mode range, long-distance transmission, the conflict protection features. But a real solid RS-485 network also depends on the reasonable application. Logical network layout, channel signal of continuity, comprehensive protection measures, designed from the outset there should be an overall plan

 项目中用到圆形进度条，首先就想到使用 ProgressBar 扩展一个，在博客园里找到 迷途的小榔头 给出的思路和部分代码，自己加以实现。在此感谢 迷途的小榔头！ 进度小于60显示红色，大于60则显示绿色。效果如下：
