说明：  PIC16F877A的使用，ADC，LCD1602，PWM输出等功能。(Use of PIC16F877A, ADC, LCD1602, PWM output and other functions)

金山安全卫士源代码，非常不错的一份，可以作为研究(Jinshan security guards the source code)

说明：  许多现代浮点单元的一项主要体系结构功能，是能够将一个乘法与后面紧跟的加法作为单个运算执 行，且没有中间舍入误差。例如，Intel 的 Itanium 体系结构提供了一些指令，将三元运算 (a*b+c) 、(a*b-c) 和 (c-a*b) 中的每一个都组合为单个浮点指令（分别为 fma、fms 和 fnma）。这些单个 指令都比执行独立的乘法和加法指令快，并且因为没有中间乘法舍入，所以更为精确。该优化可以显 著提高那些含有多个交错乘法和加法运算的函数的速度(many modern floating point unit of a major system structure and function is to be a follow closely behind multiplication and addition of implementation as a single operator, with no intermediate rounding error. For example, Intel's Itanium architecture provides a number of directives to the ternary operator (a* b, c), (a* b-c) and (c-a* b) each have a portfolio to a single floating point instructions (Fullmetal respectively, and fms fnma) . These individual instruction than the implementation of an independent and additive multiplication instructions quickly, and because no middle multiplication into homes, so more precise. The optimization can significantly increase those containing more than staggered multiplication and addition operations function of the speed)

利用DevC++写的Windows基本控件的类库,有详细的使用例子,水平有限,希望指正(Use DevC to write the Windows basic control class library, have detailed use example, the level is limited, want to point to correct)

说明：  bpa软件实现三机九节点潮流程序与稳定程序分析(BPA software three machine nine node power flow and stability program analysis)

实时读取串口数据并可用仪表和曲线进行显示(To read the serial data in real time and available instrumentation and curve display)

说明：  MFC编程 实现数据绘制成曲线。经兄弟推荐最终决定用两个控件MCSCOMM与TeeChart来完成此任务。MCSCOMM控件时vc自带的串口控件，TeeChart Pro是一个强大的VCL图表组件，支持上百种2D和3D图表风格，并提供40多个数学和统计函数、无限制的轴和22个调色板(MFC programming realizes data plotting into curves. After recommendation by brothers, we finally decided to use two controls, MCSCOMM and TeeChart, to accomplish this task. TeeChart Pro is a powerful VCL graphics component that supports hundreds of 2D and 3D graphics styles and provides more than 40 mathematical and statistical functions, unlimited axes and 22 palettes.)

直流无刷电机的TMS320F2812的控制源程序，可实现开环和闭环调速。(Brushless DC motor TMS320F2812 control source code, can achieve the open-loop and closed-loop speed control. )

高通，rex，OS，很好的文档~~~！！！(Qualcomm, rex, OS, a very good document ~ ~ ~)
