adc for mcu stm32f103

The book is organized in the form of question and answer, and discusses some of the problems often encountered in the process of learning or using the C language. For reference, not commercially available

ADC采集信号通过DMA双缓存模式读取，经串口发出(The ADC acquisition signal is read through the DMA double buffer mode, and is sent through the serial port.)

说明：  遍历文件夹并建成目录树,一个非常好的例子(Traverse Folder and build the directory tree, a very good example)

首先，我们初始化一块缓冲区，对应于参数平面，将其所有数据置为0. 　　 对于图像上每一前景点，求出参数平面对应的直线，把这直线上的所有点的值都加１。最后，找到参数平面上最大点的位置，这个位置就是原图像上直线的参数。上面就是霍夫变换的基本思想。就是把图像平面上的点对应到参数平面上的线，最后通过统计特性来解决问题。假如图像平面上有两条直线，那么最终在参数平面上就会看到两个峰值点，依此类推。 

说明：  使用STM32F407实现LD3320的语音识别(Using STM32F07 to run LD3320 of ASR)

nondominated sorting genetic algorithms，nsga2的c语言源代码，比较好。(nondominated sorting genetic algorithms，nsga2 c-language source code better.)

说明：  利用51单片机引脚实现对IIC通讯的模拟(Simulation of IIC communication with 51 MCU pin)

说明：  标准的采用G.721国际编码标准，包括编码和解码两部分，用matlab语言编写，并测试通过。(The adoption of standard international coding standard G.721, including encoding and decoding of two parts, with the matlab language, and test.)
