今早上没事干……研究计算器的键盘发现了一个惊人的秘密!先说K--点与芯片引脚的关系:首先,引脚是有序的,在引脚周围的线路上我们不难发现有带有数字白点。这就是这条线路与芯片引脚相对应的编号,它的起点是在:

<P>下面把所有的K--点和引脚的对应编号发下:

<P>如果你在工作状态按表中连接KI-和KO-,屏幕就会有对应的反映。。。</P>

good.
 楼主| 发表于 2009-12-21 23:23:57 | 显示全部楼层
回来掘坟了~~
不要以为这个图没有用……至少按键问题通过这个图可以解决……
还有这个图中电容部分和供电部分有待完善……
请高手们赐教~

A、B版的这个。。。一样么?
 楼主| 发表于 2009-12-26 20:38:01 | 显示全部楼层
完全一样……B版的P(X)引脚部分没有漏在外面
