旋转电机控制程序，采用DSP2812进行控制

说明：  EF Core增删改查，DB Frist的一些操作(Some operations of DB frist)

本例程给出了基于keil5编译环境的ADC采样的完整工程，采用的芯片为STM32F030C8T6，可以直接使用。主要功能为利用DMA实现单片机多路顺序采样。

This is dialog program. for use playing the music through the serial interface. So, this program is included RS-232.

说明：  基于STM32的智能垃圾桶，实现的功能有红外传感器检测自动开盖，LED屏显示，温湿度测量，超重报警，异味检测，可燃气体检测(Based on STM32 intelligent trash can, the functions realized include automatic cover opening of infrared sensor detection, LED screen display, temperature and humidity measurement, overweight alarm, odor detection, combustible gas detection)

QuadraticQuaassemble 的源程序 matlab有限元分析源程序 (QuadraticQuaassemble source matlab source Finite Element Analysis)

1.添加特征值 我们添加一个1Byte的特征值来控制灯的亮灭 因为simpleGATTProfile是共用的文件，为了不影响其它工程，我们使用一个宏来控制新增加的属性 #if SIMPLEPROFILE_LED #endif (1)修改simpleGATTProfile.h    (2)添加UUID //Characteristic 6 UUID:0xFFF6 (3)添加属性 // Simple Profile Characteristic 6 Properties // Characteristic 6 Value // Simple Profile Characteristic 6 User Description (4)属性表 // Characteristic 6 Declaration // Characteristic Value 6 // Characteristic 6 User Description (5)属性设置操作 SimpleProfile_SetParameter （6)属性获取操作 Get a Simple Profile parameter (7)属性读操作 simpleProfile_ReadAttrCB （8)属性写操作 simpleProfile_WriteAttrCB 2.Profile的改造完成后，我们将这个宏打开，配置工程。 3.接着我们在staticvoid simpleProfileChangeCB( uint8 paramID )函数的switch中加入CHAR6的判断即可

说明：  vc开发的管理系统，一种小软件，对开发学习的初学者会有很大帮助。(vc development of the management system, a small software development for the study will be of great help beginners.)

Sqlite3 的确很好用。小巧、速度快。但是因为非微软的产品，帮助文档总觉得不够。这 些天再次研究它，又有一些收获，这里把我对 sqlite3 的研究列出来，以备忘记。(Sqlite3 really good use. Small, fast. But for the Microsoft products, always feel that not enough to help document. This Some day to study it, and have some harvest, here I study on SQLite3 list, to forget.)

语音编码方案的选取对移动通信系统的通话质量、信道容量等有重要影响。本文讨论了TD-SCDMA系统中AMR语音编码的自适应机制，同时分析了AMR中代数码本线性预测(ACELP)算法及实现过程。该方案可以在一块TMS320C5510上实现。(The selection of voice coding schemes for mobile communication systems the quality of the call, such as channel capacity have had a significant impact. In this paper, TD-SCDMA System AMR Adaptive speech coding mechanism, at the same time analysis of AMR in the generation of Digital Linear Prediction (ACELP) algorithm and the realization of the process. The program can be achieved in a TMS320C5510.)
