vhdl 键盘程序，对键盘输入的字符进行判断，写入fpga中

说明：  HDMI做为视频输出输入接口已经广泛使用很长时间，主要通过TMDS差分编码传输。本实验通过在HDMI屏幕上显示彩条和输入输出环通实验，来练习视频的时序和视频颜色的表示，为后面视频处理实验做个基础。(HDMI as video output input interface has been widely used for a long time, mainly through TMDS differential coding transmission. In this experiment, by displaying color bars and input/output loop experiments on HDMI screen, video timing sequence and video color representation are practiced to lay a foundation for video processing experiments later)
