基于FPGA 的usb传输

说明：  实现对LCD1602的Verilog HDL编程(the program for LCD1602 based on Verilog HDL)

8对于输入密码锁的键，假设重置后七个灯显示" 0"，并且使用sw1、sw2、sw3 3，只需按任意sw1、sw2、sw3，将使七个灯显示值相加" 1

针对FPGA一个实现vga显示的很好的例程，vhdl语言编写。-FPGA realize for a good vga display routines, vhdl language.

采用vhdl代码描述自适应滤波器，具有很好的可参考性，和实用性(Vhdl code to describe the use of adaptive filter, can be found with a good nature and usefulness of)

两位独立数码管100进制计数器，每1秒计数一次。从0到99，到99后又回到0.-Two independent 100-band digital tube counters, every time 1 seconds count. From 0 to 99, to 99 and then back to 0.

是我们在在实验室做的摸60计数，并用LED显示出来。-is done in the laboratory in the loss of 60 counts, and LED show.

Spartan® -3E 现场可编程门阵列家族是为满足对成本敏感的消费电子大量应用的需要 而特别设计的。 (Field Programmable Gate Array family needs is to meet the cost-sensitive applications, a large number of consumer electronics Specially designed.)

代码使用应用于 FPGA的VHDL代码，主要是告诉大家时序逻辑和组合逻辑的应用场合和区别，希望能够对大家有所帮助

VHDL的重要PPT资料,对初学者非常有益处-VHDL important PPT information is very useful for beginners

实用的程序代码，希望对大家有用，已经调试通过-Practical program code, in the hope that useful to everybody, has debugging through
