  设计一个具有较高安全性和较低成本的通用电子密码锁，其具体功能要求如下:  (1) 数码输入：每按下一个数字键：就输入一个数值，并在显示器上的最右方显示出该数值，同时将先前输入的数据依序左移一个数字位臵 (2) 数码清除：按下此键可清除前面所有的输入值，清除成为“0000”。 (3) 密码更改：按下此键时会将目前的数字设定成新的密码。 (4) 激活电锁：按下此键可将密码锁上锁。 (5) 解除电锁：按下此键会检查输入的密码是否正确，密码正确即开锁。

模拟示波器的现实程序，有x，y和光标。采用AD5440输出，现实效果很好。（示波器x-y方式）(Analog oscilloscope reality program, there are x, y and cursor. Using AD5440 output, real good results. (Xy oscilloscope mode))

用Verilog语言实现的FPGA UART独立收发模块 思路简单，代码简洁。在Lattice LFE3EA VERSA开发板上验证通过,编译器Lattice Diamond. 功能：串口收到数据后立即回传，此后每一秒串口数据+1再发送。(Using Verilog language independent of FPGA UART transceiver idea is simple, concise code. Development board in Lattice LFE3EA VERSA verified by the compiler Lattice Diamond. Features: Serial data is received immediately after the return, then every second serial port and then send the data+ 1.)

Frame Control field
Retry:
Set in case of retransmission frame
More fragments:
Set when frame is followed by other fragment
Power Management
bit set when station go Power Save mode (PS)
More Data:
When set means that AP have more buffered data for a station in Power Save mode

csapp 第二版 体系结构实验 答案 第三个部分能跑58分(the second edition csapp architecture experiment the third part of the answer can run 58 minutes)

基于VHDL语言的串口发送和接收程序,自己调试通过，并已经运用在工程中(Based on the serial port to send and receive procedures VHDL language, its own debugging, and has been used in the project)

VHDL语言编写的计数器程序，实现1到9999计数，并动态扫描显示，带清零和暂停功能，课上作业自编程序-VHDL language of the counter program to achieve 1-9999 counts, and the dynamic scan showed, with Clear and suspension of functions, classes, on a self-compiled programs

清华大学电子课程设计：Verilog，QuartusII可正确运行，可下载到FPGA上，音乐计算器，完成两个三位数的运算，有注释，很强大！！(Verilog, QuartusII run correctly, can be downloaded to the FPGA, music, calculator, completed two three-digit operations, there are notes, very powerful! !)
