下面说的这些只是一些关于：MiniSTM32f103系列的开发板，只是博主的一些愚见 大家都知道，我们是通过usb线连接我们的开发板和电脑，我们用电脑上面的keil5软件编程，然后通过数据线下载于开发板 在开始学习stm32 1，先安装keil5，因为这个软件是我们用来编程，用来控制板子的，最后生成hex文件，从而达到我们的目的 2，CH340这个软件，它是串口的驱动

Special Gift两个月前偶然在知乎上看到有人用树梅派制作了魔镜，感觉挺神奇的，第一想法就是作为一个程序员，做一个魔镜出来送给女朋友多么酷炫啊。因为我对于单片机比较熟悉，我觉得使用STM32来做更方便，更便宜一点。到现在也基本完成了，在这记录一下我做的过程，也给大家提供一个思路。话不多说，直接开始干。材料准备 STM32开发板一套，含2.8寸液晶屏 。（价格在180左右） cc2541蓝牙模

魔镜是一个很好玩的树莓派应用，不但可以照镜子，还可以看天气和时间，很有实用性。是一个可以动手的不错的小项目。     在这里，借鉴和学习了http://www.hellowk.cc/14834426274852.html中的经验，但是由于时间过去比较久，树莓派的系统更新，有些地方已经不再适用。我在体验过程中遇到的各种问题，在这里一一列举，希望能够帮到以后的学习者。      安装 Apac
