小知识:  
    使用easy\_install或pip安装Python第三方库时,默认源地址是:https://pypi.python.org/simple/  
这是这个源有几个问题:  
    1.国外的网站访问速度比较慢.  
    2.使用该源遵循http协议,若机器上没有安装openssl或ssl配置不对,将导致easy\_install或pip访问该源              
    失败,若想解决这两个问题，  
     可以使用国内的PyPI镜像源(会定期的把国外的软件拷贝到这个库中)。  
    国内的一些pipy的镜像源:  
        1.清华源:  https://pypi.tuna.tsinghua.edu.cn/simple  
        2.豆瓣源:  https://pypi.douban.com/simple  
        3.pypi.hustunique.com  
   
   
访问国内的pipy源时,安装命令为:  
      pip install 库名==1.11.11 -i https://pypi.tuna.tsinghua.edu.cn/simple

虽然提示一个ERROR，但把pyyaml包切换到4.2b1版本，则无法生成uvision工程，所以还是切回来5.3版本，忽略

错误，最终生成了工程：

DAPLink是一个github开源项目，可以用于M内核MCU的在线仿真及离线下载、虚拟串口等功能。（Flash>=128KB）

计划制作开源的DAPlink（用于USB 2.0 全速12Mbps学习/以及USB设备开发）,总成本预计15元:

对比了两款芯片：STM32F072RB LQFP64  目前市场淘宝价格在7元左右和STM32F103RB LQFP64价格差不多，

但103为M3内核，主频比072 M0高，一个72MHz，一个48MHz，两者为同一容量等级128KB flash，

所以最终选择**STM32F103RB**，同时发现STM32F103RC的价格却只有6元，奇怪的是，它是256KB的容量理论上应该要更贵一点。(首件优惠，所以6元，实际价格为9元)

CB/TB封装比RB要小为48/36pin，实际DAPLink并用不到那么多的引脚，所以希望封装越小越好，但发现同等规格参数，封装越小反而价格越高(好像贵的还挺多^\\^)，所以放弃了选择。

正规点的网站这个片子还是挺贵的，不太清楚为什么淘宝那么便宜，既然淘宝上有一定的销量应该不会是假货吧，可能只是渠道不同：

50元/10片的打板费用，分摊到20块板卡（计划双拼板/或多拼板），每块板约2.5元，还剩5元可以用于晶振、按钮、排针、LED、LDO、USB接插件等的购买。加上快递费，制作完成后计划在淘宝上以15-20元的价格发售（目前市场上的最低价格大概是28元）。希望有人买，自己做着玩的，只要不太亏就行^\_^。

制作后期希望能增加一些附加功能：并具有开发板性质
