s3c44b0chumoping
- 当手指或笔触摸屏幕时,平常相互绝缘的两层导电层就在触摸 点位置有了一个接触,因其中一面导电层接通X轴方向的5V均匀电压场(图a) ,使得检测层的电压由零变为非零,控制器侦测到这个接通后,进行A/D转换 ,并将得到的电压值与5V相比即可得触摸点的X轴坐标为(原点在靠近接地点 的那端):Xi=Lx*Vi / V(即分压原理)同理得出Y轴的坐标,这就是所有电 阻技术触摸屏共同的最基本原理。-finger or pen to touch the screen, usually two

MicroC-OS-III-
- UCOS-III中支持了时间片的轮转调度,为了减少关中断的时间, 内核在对临界段的处理上使用了一些方法,比如为防止中断中访问 临界段代码,把中断的事情分两步来做,即中断中把对内核的操作 仅做保存,实际的操作推迟到一个称为OS_IntQTask中完成!这样 就可以在程序中使用禁止调度的方式来处理临界段的代码,也大大 减少了关中断的时间!但这并不意味着这种方法就是最优了,它是在 任务切换的消耗和关中断的时间来平衡的,所以UCOS-III也支持使用 关中断的方
