步进电机控制程序，用vhdl实现。可实现电机的正反转控制

随机数发生器

基于fpga的多功能数字时钟的实现，已经编译过了，绝对可行-fpga-baseed clock

使用PWM控制LED亮度的单片机C代码，共计十个亮度。(PWM control of LED brightness microcontroller C code, for a total of ten brightness.)

试设计一种彩灯控制器控制8盏灯。该彩灯控制器有4种自动切换的花样。第一种花样为彩灯从右到左，然后从左到右逐次点亮，全灭全亮；第二种花样为彩灯两边同时亮一个逐次向中间移动再散开；第三种花样为彩灯两边同时亮两个逐次向中间移动再散开；第四种花样为彩灯两边同时亮三个，然后四亮四灭，四灭四亮，最后一灭一亮。四个花样自动变换，重复以上过程。输入时钟频率为500Hz，灯亮的时间在1―4秒之间，可以自由控制。电路中以“1”代表灯亮，以“0”代表灯灭。-Lantern try to design a controller to control 8 lights. The controller has four kinds of lanterns automatically switch the pattern. The first lantern pattern for right-to-left, and then lit from left to right each time, the whole body light second pattern for a lantern light at the same time on both sides of successive spread to the middle of moving again third pattern for lantern light at the same time on both sides to the middle of two successive re-dispersed mobile fourth pattern for the lantern light at the same time on both sides of the three, then four out four bright, four out four-liang, the last light out. Automatically transform the four patterns, repeat the process above. Input clock frequency of 500Hz, the time for lights between 1-4 seconds, they can con

VIVADO SOC 使用文档 基于zynq 7020(vivado soc example text of zynq)

说明：  使用Verilog HDL ，FM调制信号。(Using Verilog, HDL, and FM modulation signals.)

使用Altera公司的FPGA进行VHDL开发。使用quartus2 9.0软件在EP1C3T144C8开发板上实现对一个十字路口的交通灯的控制，包括4个红绿灯和4个2位的数码倒计时器。-The use of Altera" s FPGA-VHDL development. Use quartus2 9.0 software EP1C3T144C8 development board to realize a crossroads traffic lights control, including four traffic lights, and four 2-bit digital countdown device.

计时范围为59.99秒；有计时开始和停止计时控制，复位控制可以对所有计时进行异步复位；计时结果由四位七段数码管显示。
