游侠再次让卡西欧喷写血

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:

游侠 发表于 2009-2-6 16:55:11

<P>附张自己研究的电路图</P>
<P>按键那面的</P>

游侠 发表于 2009-2-6 16:55:33

那个掉的是153,有点不清

不锈钢 发表于 2009-2-6 18:22:21

貌似没啥用

chsi 发表于 2009-2-6 19:17:25

快成抄板的了

游侠 发表于 2009-2-8 17:57:28

<P>抄好的板</P>

zhs490770 发表于 2009-2-26 19:58:54

good.

游侠 发表于 2009-12-21 23:23:57

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~

朔雪X忆 发表于 2009-12-22 09:47:04

A、B版的这个。。。一样么?

游侠 发表于 2009-12-26 20:38:01

完全一样……B版的P(X)引脚部分没有漏在外面
