先在树莓派上运行rpi，此时它会在5001端口上监听TCP连接。
当GPIO23和VCC相连时，为电键接通，PWR_LED（红色）会亮起，并向连接的客户端socket发送字节1；反之断开时，为电键断开，PWR_LED熄灭，并向连接的客户端socket发送字节0。
在电脑（使用X11的Linux）上运行host，把IP地址改成树莓派的地址，就可成功连接。电键触发与断开就会分别发送mousedown和mouseup。

由于当时发的帖不是很好找（现在不怎么用百度贴吧了，百度里搜我的id也搜不到），往这记一份。
简便乱字+异常菜单 刷an，光标移到an左边 由于电脑不在身边，所以只能用纯文字叙述了，输入就是在数学模式下。 六个分数线，从上到下分别是√11，√(11√(11))，11，11，11，11 然后按=，6除2，八个左括号，2+1，=，AC 此时就乱字+异常菜单。菜单，科学常数，单位换算和复位都有乱字，但是不完全，有的还是原来的。 这个模式容易死机，设置中不能下翻，否则死机；菜单中貌似右键没用，左键只能按最低三下，否则死机。计算也会死机。
