二极管发光代码

说明：  该资料是用vhdl编写的按键消抖程序，按键消抖在使用按键的数字电路中非常重要，如果不对按键信号进行处理，有可能会出现大量错误的按键信号。文件key_xd.vhd是按键消抖程序，文件key_xd.vwf是仿真波形文件。该程序已经通过仿真测试，并且在电路板上调试通过，效果理想。(The information is written in the key consumer vhdl shaking procedures, key consumer shaking in digital circuits using the buttons is very important, if not key signal processing, there may be a lot of the wrong button signal. File key_xd.vhd is key consumer shake procedure is the simulation waveform file key_xd.vwf file. The program has been tested by simulation and debugging in circuit board by, the results are satisfactory.)

LCD图形显示代码，已调试过，可以运行成功(LCD graphics display code has been debugged, you can run successfully)

Verilog RS232代码， 分为三个模块，时钟产生模块，发送数据模块，接收数据模块。 整个工程的功能是，你从串口上位机发送什么数据，串口就将该数据重新发送回上位机

本文档介绍了Verilog双精度浮点内核，这些

MPSK调制与解调VHDL程序源代码与仿真(MPSK modulation and demodulation process and VHDL source code and simulation)

Very good info. for RS-232 echo VHDL code .

良好的Coding Style能减少Bug，减少锁存器出现的可能以及其他隐藏逻辑错误，也有助于减小芯片面积或所用资源(Good Coding Style can reduce Bug, reduce the possibility of latches and other hidden logic errors, and also help to reduce chip area or resources used.)

用verilog写的，基于查表法实现的LOG10运算器，在Altera FPGA中应用。(It is a verilog design of LOG10 calculation unit, which is based on LUT arithmatic. And it is applicated in Altera FPGA.)
