*先后调试了LED，按键，数码管的verilog程序，并在实验板上面调试成功！学习FPGA是一个漫长的过程，但是我必须得坚持！前途光明，道路崎岖！

这次在垃圾堆（我工作台下面的抽屉和柜子，呵呵）里面搜索了一个以前用C8051F020作的一个单片机 最小系统，其中有一个PS2的数字小键盘，于是马上鼓捣了一下，复习了一下PS2传输数据的规则，其实还是比较简单的，所以很快就把程序搞定，并在电路板上运行正常！！！

-* Has a debug LED, button, digital control verilog procedures, and debugging in the experiment above board success! FPGA is a long learning process, but I have to insist! A bright future, roads and rugged! In the garbage (I workbench drawers and cabinets below, huh, huh) search inside a previously C8051F020 minimum for a single-chip systems, which have a small number of PS2 keyboard, then immediately鼓捣, then review the PS2 data about the rules, in fact, relatively simple procedures so they get very quickly, and in the normal operation of the circuit board! ! !
