第七章第一讲

【实例简介】基于TCP协议的网络聊天室

通过单片机stm32f103rbt6来采集充电回路上的电流和电压，然后经过算法处理后输出相应的PWM信号来驱动开关管，从而控制BUCK电路实现对锂电池的闭环充电控制。(Through the MCU stm32f103rbt6 to collect the charging current and voltage loop, and then through the algorithm outputs the PWM signal corresponding to the driving switch to control the BUCK of lithium battery charging circuit closed-loop control.)

74HC138驱动数码管程序，驱动4位共阳数码管，阳极全部高电平，138驱动段码(74HC138-driven digital control program)

设置输入方法，C++Builder精选编程学习源码，很好的参考资料。(Set the input method, C++Builder select learning programming source code, a good reference.)

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)

此程序生成狄洛尼三角网．运用了简单的读取文件．然后依据算法生成三角网．(this program generator Diluoni triangulation. Use a simple read files. Then generation algorithm based on triangulation.)

c#语言实现三维点云文件的读取以及opengl显示(c# language to achieve a three-dimensional point cloud file read and opengl display)

用MFC实现了tif格式到bmp格式的转换，值得下载(Using MFC to achieve a tif format to bmp format conversion, it is worth downloading)

说明：  对HT1621的驱动，提供C及汇编代码， 注有详细的代码说明，在C51，PIC上测试OK， 绝对有用。(The driver of the HT1621 to provide C and assembly code, annotated with detailed code instructions, in the C51, PIC test OK, not in vain.)
