文档介绍：课题: 基于 BASYS2 的电子琴设计【摘要】本项目要求设计并实现一个基于 BASYS2 的电子琴,利用 BASYS2 实验板的拨码开关实现电子琴相应功能的控制,电子琴的输出有两个声道,可独立输出。该电子琴可外接 PS2 键盘,实现电子琴按键功能,同时外接 VGA 显示器实现电子琴的界面。该电子琴还具有存储输入按键值并回放功能。【关键词】: FPGA 、BASYS2 、电子琴、 PS/2 、VGA Abstract : This project isaimed atdesigning anelectric piano based onBASYS2. The switch onthe BASYS2 will control the function ofthe electric piano. This piano with two different audio channel, can also memory the keys which have been pressed and replay them. This piano can beconnected toaPS/2 keyboard, which plays arole ofkeys ofthe piano, and connected toaVGA monitor, which could display the interface ofthe piano.
