在多跳无线网络进行TDMA方式接入时候，时间是被划分为互不重叠的时隙，边长或定长帧在时隙中进行传输。 当面向节点时候，一个节点可以得到一个或者多个时隙，节点可以利用这些时隙向任何一条链路发送报文到邻居节点。 面向链路分配时候，则是某条单向链路分得一个或多个时隙，在这些时隙中，报文发送是单向的。(Time is divided into non-overlapping slots when multi-hop wireless networks are accessed by TDMA mode. Side-length or fixed-length frames are transmitted in slots. When facing a node, a node can get one or more slots, which can be used by the node to send messages to any link to its neighbors. For link allocation, a one-way link is allocated one or more slots, in which message transmission is one-way.)

当AIN0引脚上模拟采样电压高于AIN1上模拟采样电压时，模拟比较器 输出置位，PORTA口高四位LED亮低四位LED灭；反之AIN0<AIN1时，PORTA 口高四位LED亮低四位LED灭。(When AIN0 pin AIN1 analog sample voltage is higher than the analog voltage sampling, the analog comparator output digital home, PORTA I LED light low-high four out of four LED contrary AIN0 <AIN1 when, PORTA I high four LED light 4 LED low eradication.)

Linux0.11内核源码适合研究阅读，其中包含进程管理，进程间通信，文件系统、内存管理、没有网络；虽然没有网络部分的实现代码，但是研究Linux内核，0.11版的内核代码量小。值得阅读品味。。。。。。。
