CPLD下载线制作，内含电路图等，希望对大家有帮助

代码实现了一个根升余弦成型滤波器，2PAM信号通过此成型滤波器，并且匹配接收，画出了发送和接收波形，验证了代码的正确性。(The code designs a root raised cosine filter,2PAM signal transmitted through the filter and matched using the same filter, I plot the transmitted signal and received signal to verify the correctness of the code.)

基于Xilinx公司的ISE软件开发的智能循迹避障小车的源代码，用Verilog语言，传感器有红外传感器以及超声波传感器(Xilinx' s ISE-based software development intelligent car tracking avoidance source code, using Verilog language, the sensor has an infrared sensor and ultrasonic sensors)

讲述4ASK的原理并附有matlab调制解调的源码。。。。。。。。。。 注：原来上传的4ASKmod.zip不要下(The principle tells 4ASK together with modulation and demodulation matlab source. . . . . . . . . . Note: The original upload 4ASKmod.zip not down)

基于PCF8591数模转换和DDS技术的信号发生器系统设计(Design of Signal Generator System Based on PCF8591 Digital-to-Analog Conversion and DDS Technology)

SPI读写AD9361，通过串口回读关键寄存器读写是否正确。(SPI reads and writes AD9361, reads and writes the key registers correctly through the serial port.)

0-99记数VHDL的源程序,综合实验指导书上的,可以用的 大家下载哦 -0-99 notation VHDL source, comprehensive guide book on the experiment can be used by everyone to download Oh

在ise开发环境下，建立顶层模块和子模块的层次结构，其实现的功能是一个可复位课暂停开始继续的建议秒表(In ise development environment, establish a hierarchy of top-level modules and sub-modules, and its function is to achieve a resettable class resumes proposal to suspend the stopwatch)

MD5 算法在Xilinx FPGA上的实现，希望对大家有用。(MD5 algorithm in Xilinx FPGA Implementation, in the hope that useful to everyone.)

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.)
