数字电子设备上下计数器的实现

altera max10 USB demo，使用了phy，把开发板配置成U盘模式(altera max10 USB demo，using PHY device，design a U pan)

floating point alignment

LVDS的应用的Verilog HDL例子程序(LVDS example of the application procedures for the Verilog HDL)

基于fpga的电子血压计。pdf文档，好用，内容清楚简单，转载而来(Electronic sphygmomanometer based on fpga)

说明：  利用正点院子开拓者fpga实现DDS功能，实现三角波、正弦波、方波的发生。(Implementation of DDS with FPGA)

本实验教程选用Xilinx公司的产品X9572，与之配套的开发软件为ISE4.1i，可进行原理图的输入和VHDL硬件描述语言的输入，并且可利用Modelsim进行功能仿真和时序仿真。-In this study, selected Xilinx tutorial products X9572, with supporting the development of software for ISE4.1i, schematic can be input and VHDL hardware description language input, and can use Modelsim functional simulation and timing simulation.

本程序是用VHDL语言实现电子密码锁功能,整个系统分为三大模块,一为控制模块,二为键盘显示模块,三为处理模块-This procedure is a VHDL language electronic code lock function, the entire system is divided into three modules, one for the control module, two for the keyboard display module, three modules for the treatment

该程序用vhdl编写的vga显示的小游戏，到时屏幕上会显示一个小球，一根棒子，一面墙，棒子可以通过按键控制来移动。而小球在不停的运动，遇到墙会反弹。(Game written by the program with VHDL VGA display, the screen will display a small ball, a stick, a wall, stick to move through the key control. Ball in constant motion, encountered the wall will bounce.)

这是一个LCD1602底层驱动代码，TI公司LM3S系列的(This is a LCD1602 underlying driver code, TI company LM3S series)

说明：  实现串口通讯以及SLIP协议传输数据，增加了特殊字符的转义(Realization of Serial Communication and SLIP Protocol)
