- 扫描信号从C3 ～C0送入,信号依序为1000 ->0100 ->0010 -> 0001->1000 循环,当扫描信号为1000时,则扫描第0行中的四个按键. 扫描信号为0100时,则扫描第1行中的四个按键, 以此类推.如果有按键被按下,则R3～R0的输出信号中会有一个为1,但我们还是是无法确定哪一个键被按下,必須要从R3 ～R0 的输出信号与C3～C0的-scan signal from C0 to C3 into the signal in order of 100

- Verilog HDL编写的键盘扫描程序，考虑了判断按键弹起的问题。程序按一定的频率用低电平循环扫描行线，同时检测列线的状态，一旦判断有一列为低则表示有键被按下，停止扫描并保持当前行线的状态，再读取列线的状态从而得到当前按键的键码；等待按键弹起：检测到各列线都变成高点平后，重新开始扫描过程，等待下一次按键。-Written in Verilog HDL keyboard scanner, taking into account to determine key bounce problem. P
