利用开发板实现键盘的功能，参考性很强。草泥马，屁事那么多-implement keyboard development using vhdl

VHDL有些项目可作为一个参考，水灯，串行端口，键盘，数字控制等-VHDL some projects can be used as a reference, water lights, serial port FIR, keypad, digital control and so on

使用Verilog HDL 以及VHDL语言，运用FPGA中的VGA显示原理以及键盘控制原理，开发汉诺塔简易游戏(The use of Verilog HDL and VHDL language, the use of FPGA in the VGA display principle and keyboard control principle, the development of Hanoi simple game)

VHDL代码，共10个程序，分别是1分频器2状态机3计数器4拨码开关对应数码管显示5键盘及显示6键盘显示7交通灯8汉字滚动9ADC0804直流采样和显示10正弦波发生器(A total of 10 procedures, namely, 1 frequency dividers, 2 state machines, 3 counters, 4 dial switches, corresponding to digital tube display 5 keyboard and display 6
