摘　　要：以现场可编程逻辑器件(FPGA)为核心的PS/2接口键盘的输入输出电路实验来了解多模显示器在VGA上的内容。利用QuartusⅡ软件编写verilog HDL硬件描述语言程序以实现数码管循环显示学号以及根据键盘切换输出波形并在VGA上显示。本设计主要以程序为核心,硬件电路的搭建使用DEO板,将程序顶层文件里定义的输入输出端口与DEO板上的管脚进行相应的配置,外设是一个与实验箱通过PS/2接口相连的键盘和VGA接口相连的显示屏。当系统上电后,DEO板上的数码管会循环显示学号后四位;按下键盘上的按键,VGA上会显示当前温度和时间以及学生姓名。通过实验来了解多模式显示器在VGA上显示不同的内容。The design is based on the site of Field-programmable gate array （FPGA） as the core of PS/2 keyboard input and output interface circuits. Quartus 11 use software to write verilog HDL hardware description language program to achieve digital learning cycle number and the switching of the output waveform according to the keyboard and display on VGA. The program is designed to be the core, build the hardware circuit board using DEO will make the appropriate configuration program to define the top-level file input and output port pins and DEO board, Peripherals is an experimental box by PS/2 keyboard and VGA display interface connected to the interface connected. When the system is powered, DEO will loop digital control panel display after school number four;press the button on the keyboard, VGA displays the current temperature and time as well as the student＇s name.
