基于FPGA 的usb传输

FPGA实现增量式光栅尺正交脉冲解码，基于Verilog(FPGA realization of incremental grating ruler orthogonal pulse decoding, based on Verilog)

说明：  使用Verilog编写的24位定时器，具有apb 总线接口，可以设置工作方式和计数初值。(The 24-bit timer written by Verilog has APB bus interface, which can set working mode and count initial value.)

说明：  OFDM信号的发送与接收 ，需要自取。时域图，模糊图，削峰。(Sending and receiving of OFDM signal)

基于FPGA设计的电子密码锁是一个小型的数字系统，与普通机械锁相比，具有许多独特的优点：保密性好，防盗性强，可以不用钥匙，记住密码即可开锁等。(FPGA-based design of the electronic code lock is a small digital system. It has many unique advantages：good privacy and security , it do not need the key but remember password to unlock, and so on while it compare to ordinary mechanical locks.)

基于fpga和xinlinx ise的鼠标应用vhdl程序，希望对你有所帮助！-and they simply based on the mouse xinlinx ideally VHDL application procedures, and I hope to help you!

说明：  基于FPGA的数字式相位测量仪的设计与制作(FPGA-Based Digital Phase Meter Design and Production)

基于FPGA的1602时钟显示,驱动1602显示时钟,矩阵键盘调时(1602 FPGA-based clock display, clock display driver 1602, when the transfer matrix keyboard)
