stm32f103c8t6实现USB虚拟串口

说明：  一种用于文件压缩的算法，可用于压缩数据量较大的文件，有很高的压缩比(An algorithm for file compression, which can be used to compress files with large data volume and high compression ratio)

stm32f103vet6实现printf重载(printf function about stm32f103vet6)

此代码是自己写的三层结构代码生成器，针对sql，生成虚拟工厂，很好用的。对于初学结构的同学很有帮助的。上传大家学习下。

说明：  这是采用stm32L151主芯片驱动NB做云端通信，采用GPS定位。和采集温度。加震动检测。休眠状态达到9umA。(This is the use of stm32L151 main chip to drive NB for cloud communication and GPS positioning. And collection temperature. Add vibration detection. The sleep state reaches 9umA.)

此演示 c 程序的功能，打造一个小 reasvevation 系统

嵌入式系统：基于ARM920T嵌入式音视频压缩系统设计(Embedded system: based on the ARM920T embedded audio and video compression system design)

C#调用Matlab2008b的两个例子，如果没有安装Matlab2008b，至少要安装MCRInstall.exe v7.9(C# call Matlab2008b example, if not installed Matlab2008b, at least to install MCRInstall.exe v7.9)

说明：  非常好的图像处理全面软件，包括滤波等基本操作(Very good overall image processing software, including basic operations such as filtering)

一个数字类型可提高开关电源的设计与实现，可以是很好的借鉴，但是要用特殊软件打开，把文件后缀复制到百度就可以找到(A digital type can increase the switching power supply design and implementation, can be a good reference, but use special software to open, copy the file suffix can be found on Baidu)

一个经典的MVVM案例，非常有利于新手学习(A classic MVVM case is very helpful for beginners to learn.)
