stm32 模拟I2C通讯源码

用vs实现绘制基本的图形，曲线，矩形，图像等，且属于联机绘图(Vs the drawing using the basic graphics, curves, rectangles, images, and graphics are online)

这是用ARM和c编写的2410的启动代码(ARM and c prepared in 2410 bootcode)

说明：  系统根据进程给出的标识符,找到相应的套接口结构,可以(According to the identifier given by the process, the system finds the corresponding socket structure, and can)

用C语言编程实现一个万年历，可以很方便的使用！！(C language programming a calendar, you can easily use! !)

Complex of three-point Gauss-lengend the Formula pi, Including orbital maneuvering simulation, initial orbit calculation, University of numerical analysis algorithms.

对文件进行RLE行程编码和解码操作，在Linux上用gcc编译通过，测试正常。文件README中有详细地用法介绍。代码的细节处注释详细。仅推荐作为了解行程编码的实现，对文件操作没有太大的意义。

说明：  生成PI的一个小程序 可以精确掉小数点后几百位。 (PI generated a small program can accurately swap places after the decimal point a few hundred.)

操作系统文件管理实验：利用交互式命令实现树型目录结构和文件管理,同时利用位示图表示外存的分配情况，新建文件时分配必要的空间，模拟文件分配表记录文件在外存上的存储方式。了解系统对文件的操作。 在文件中保存目录内容，创建文件或子目录可以用命令行命令：MD、CD、RD、MK（创建文件）、DEL（删除文件）和DIR(Operating system file management experiment: the use of interactive command tree directory structure and file management, while taking advantage of the bit map indicates the distribution of the external memory, and allocate the necessary space when a new file is created, the simulation file allocation table log file is stored in the external memory way. Understanding of the system operation on the file. Save the contents of a directory in the file, create a file or subdirectory can use the command-line command: MD, CD, RD, MK (create a file), DEL (delete files) and DIR)

这个demo是一个twain协议实现的demo(This demo is a demo implemented by Twain protocol)

说明：  stm32+风速风向的测量，通过模拟量输入经过adc转换，测量风速及风向(STM32 + wind speed and direction measurement, through analog input through ADC conversion, measurement of wind speed and direction)
