按键边缘检测

基于单片机显示原理的IO和LED显示原理(Based on the principle of IO chip and LED display shows the principle)

此设计采用Verilog HDL硬件语言设计,在掌宇开发板上实现. 将整个电路分为两个子模块，一个提供同步信号（H_SYNC和V_SYNC）及像素位置信息；另一个接收像素位置信息，并输出颜色信号。这样便于进行图形修改，同时也容易实现- This design uses Verilog the HDL hardware language design, realizes on the palm space development board Divides into two stature modules the entire electric circuit, provides the synchronized signal (H_SYNC and V_SYNC) and the picture element positional information; Another receive picture element positional information, and output color signal. Like this is advantageous for carries on the graph to revise, simultaneously is also easy to realize

帧激励产生器，用于VMM仿真中生成所需要帧以供测试所用(the use for test)

基于ALINX AX7020硬件平台的USB-OTG通信程序。操作系统采用uCOS III v1.41，基本实现了双向USB2.0 块传输（Bulk Transfer）通信，zynq的PS端接收USB数据并回传至主机。经测试，主机端Window10系统采用libUSBK编程时，采用64字节的块时，传输速率可达210Mbps。zynq开发工具为Vivado2015.4，程序包中包含了全部的硬件和软件工程文档。(A USB-OTG communication project where an AX7020 platform is employed as USB device. The embeded operating system is uCOS III of version 1.41, and the FPGA toolchain is Vivado 2015.4. This project implements a full speed bidirectional USB2.0 bulk transfer. A test on Windows 10 host with libUSBK shows that the transfer speed is up to 201Mbps.)

基于FPGA的调制，实现了QPSK调制，所用芯片为Artera的CycloneIIEp2C5T114C8-FPGA-based modulation, realize the QPSK modulation, the chip used for Artera

8选1程序，是利用vhdl编写的，自己弄得还能用，上传下(8 Select a program is written using vhdl, allowed herself can use to upload the next)

*** ***OC_I2C_Master使用说明*** ***** 使用步骤：1.将OC_I2C_Master文件夹拷贝到安装盘alterakits ios2components目录下。 之后重新打开SOPC Builder，在可用元件列表的DeviceSOPC组中将出现OC_I2C_Master 元件，即可像其它Altera外设元件一样添加和使用。 2.hdl文件夹中包含有描述i2c逻辑的硬件描述文件，不能删除。 3.HAL文件夹包含硬件抽象层所需的文件（即驱动），不能删除。 4.inc文件夹包含有定义底层硬件的C语言头文件，不能删除. 5.I2C_doc文件夹下有关于该元件的开发文档。-********* OC_I2C_Master use*********** use these steps: 1. OC_I2C_Master folder will be copied to the installation disk alterakits ios2components directory. Re-open after the SOPC Builder, a list of available devices will appear DeviceSOPC Group OC_I2C_Master components, can be similar to other peripheral devices like Altera add and use. 2.hdl folder contains logical description i2c hardware description files, can not be deleted. 3.HAL folder contains the necessary hardware abstraction layer file (ie drivers), can not be deleted. 4.inc folder contains the definition of the underlying hardware C language header files, should not delete. 5.I2C_doc folder on the developmen
