- 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

- 4位数码扫描显示电路,我们控制一个七段LED需要8个输出端口;如果要输出四位十进制数,就需要32的输出端口,这将占用大量的端口资源。采用串行扫描显示,我们只需要8+4共12个端口即可。其原理是:用一个四位的输出端控制,某一时刻只选中其中的一个LED(输出为‘1’表示选中),八位的输出端将该LED所需要显示的值输出;然后四位的输出端值改变,选中下一个LED。这样依次类推。如果选择的频率很快,达到50Hz以上,由于人眼的视觉暂留效应,看起来就像4个LED同时显示。 设计一个程序,输入四个一位十
