基于可编程器件设计的一个电路，可以实现矩阵键盘的连续输入和数码管的移位显示功能。
1)连续按下按键0~9 、A~E，数字和字母将依次显示在4 位数码管上。
2) 按下F 时，数码管上不显示 F，当前显示的数字按一定频率闪烁。直至按下其他数字和字母后，再次稳定显示4 个数字。以此类推。
3)任何时刻按下实验板上的RST 键，可将电路清零.
-Verilog, QuartusII run correctly, can be downloaded to the FPGA. Could display the keys you press on the keyboard, continously. "F" can control the "shining".
