dp_xiliux the CPLD Verilog design experiments, 7 LED demo. code test.

此练习的目的是要了解如何连接简单的输入和输出到 FPGA 芯片的设备和 实现电路，使用这些设备。我们将作为投入 DE2 系列主板上使用 SW17

FPGA控制SRAM读写时序源码，代码桂发，新手一看就懂(FPGA control SRAM write timing source code Guifa novice understand at a glance)

数字信号处理的FPGA实现, 包括了FPGA基础知识，浮点运算，信号处理的FIR FFT等，附录包含源代码(Digital signal processing FPGA implementation, including the basic knowledge of FPGA, floating point operations, signal processing FIR, FFT, etc., the appendix contains the source code)

vhdl编写的4X4键盘扫描程序，可以有效的消除抖动，并且提供蜂鸣器输出。(VHDL prepared 4X4 keyboard scanner, you can effectively eliminate jitter and provide buzzer output.)

vga controller vhdl, it draws 3 lines -vga controller vhdl, it draws 3 lines

该代码实现了对SD 卡的读写操作，是一个较好的范例。(The code achieves access reading SD CARD based on DE-2，It is a good example。)

FPGA实现SPI接口的从机功能，接收和发送全双工运行，接收到的数据以八位LED灯显示(FPGA to achieve the SPI interface the machine function, receive and send full-duplex operation, the received data to eight LED lights)

说明：  对于有经验的用户和新用户写的，这本书给您的Verilog HDL的广泛报道。该书强调了实际设计和验证的角度，而不是只注重Verilog的语言方面。(Written for both experienced and new users, this book gives you broad coverage of Verilog HDL. The book stresses the practical design and verification perspective ofVerilog rather than emphasizing only the language aspects. )

数字钟，数字电子技术课程设计常用内容，基于basys3平台(Digital clock, digital electronic technology curriculum design commonly used, based on the basys3 platform)
