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 1000-gt; 0100 - gt; 0010 - gt; 0001 - gt; 1000 cycle, when the scanning signal to 1000, then scanning 0 line of four keys. Scanning signal for 0100, then scanning resolution a line of four buttons, and so on. if a button is pressed, R3 ~ R0 the output signal will be one to one, but we are unable to confirm which a key is pressed, we must proceed from R3 ~ R0 with the output signal of C0 to C3
