Description: FPGA上的VERILOG语言编程。通过查找表实现直接数字频率合成。在主控部分通过键盘选择正弦波，方波，三角波，斜波，以及四种波形的任意两种的叠加，以及四种波形的叠加；通过控制频率控制字C的大小，以控制输出波形频率，实现1Hz的微调；通过地址变换实现波形相位256级可调；通过DAC0832使波形幅值256级可调；通过FPGA内部RAM实现波形存储回放；并实现了每秒100HZ扫频。-FPGA on the verilog language programming. Lookup table through direct digital frequency synthesis. In part through the control of the keyboard to choose sine, square, triangle wave, sloping wave, and four arbitrary waveform two superposed and the stack of four waveform; by controlling the frequency control word on the size, in order to control the output waveform frequency, 1 Hz to achieve the fine-tuning; Address transform through waveform phase adjustable 256; DAC0832 so through waveform amplitude adjustable 256; FPGA through internal RAM to the waveform storage intervals; and achieve a 100 per second sweep 9999.

Description: This is a timestamp class that stores dates and times from year 0 – year 9999 and beyond. It stores timestamps up to an accuracy of hundredths of a second It can be constructed using a range of different formats, it can output individual components as well as strings in various formats, and it includes comparison operators as well as some basic date arithmetic (add day, add month, etc.). This class is aware of leap years, but not leap seconds-This is a timestamp class that stores dates and times from year 0- year 9999 and beyond.

Description: 我用单片机8952和电压比较器339做了一个简单的电容容量测量表，参数大
致如下：
电容测量范围为1pF-9999.99uF，最小分辨力为1pF。分为5个量程，可以自
动切换量程，也可手动切换。
另外，有简单的频率计功能，能测量0-60MHz的数字信号频率（TTL电平）；
还可以产生几个单点频率的方波信号（比如1KHz）。
采用1602LCD作为显示器；4个按键控制；使用24C01保存当前设置值，不用
每次开机重新设置。可单5V供电，也可9V交流供电
-I used the single-chip 8952 and the voltage comparator 339 to do a simple capacitance measurement table, parameters are as follows: capacitance measurement range 1pF-9999.99uF, the minimum resolution for the 1pF. Divided into five ranges, you can automatically switch range can also be manually switched. In addition, a simple frequency meter function, capable of measuring 0-60MHz frequency digital signal (TTL level) can also lead to several single-point-frequency square-wave signal (for example, 1KHz). 1602LCD used as a monitor 4 button control use 24C01 to preserve the current settings, do not reset each boot. Can be a single 5V power supply, 9V AC power supply can also be

Description: 俄罗斯方块网络游戏的服务器和客户端程序
写了一个本地的多线程游戏服务器ThreadeEchoServer，地址和端口为：127.0.0.1：9999
写了一个本地的多线程游戏客户端client，用来连接服务器，并进行通信．
在客户端下可以启动两个小游戏：连连看和俄罗斯方块．都需要网络服务器做出响应才能启动，可以建立客户的多线程，也就是多个客户连服务器．同时可以在一个客户实现同时玩两个游戏．
运行方式：先编译生成所有的class文件，本地启动服务器，再启动客户端，在客户端进行选择操作，来启动游戏，按面板提示进行游戏，最后退出客户端即可．-err

Description: 本代码包为本人的一篇文章<一个占用内存极少的菜单系统的实现>在在PC上的测试移植代码。
------------------------------
Menu_Src目录为Menu的源代码
Ks0108.C的void Display_Locate(unsigned char DisplayData, unsigned char X, unsigned char Y)函数为最底层的显示函数。
该函数调用LCD模拟函数来完成显示。
KeyScan.C的unsigned char KeyScan(void)函数为键盘模拟函数。
void DelayMs( WORD time ) 延时
------------------------------
GUI_SIM.exe为编译后的文件,可以直观看到这个GUI的效果.
PC键盘的4个按键控制菜单周转:
PC按键 菜单中功能
up 向上键 确定键 进入子菜单
down向下键 取消键 返回父菜单
left向左键 向上键 菜单项上一项
right向右键 向下键 菜单项下一项
有兴趣自己编译VC工程:\Project\Menu.dsw
