单片机是一门实践性非常强的学科,为此我们突破传统思路,全面围绕单片机试验,从简单的流水灯开 始, 逐步的带领大家从这些简单的几行或者10 几行的程序,来熟悉和理解单片机的指令. -Single-chip is a very strong practical subjects, and we break through the traditional idea of a comprehensive focus on single-chip testing, from simple water lights began to gradually lead the U.S. from these simple few lines or a few lines of 10 procedures to familiarity with and understanding of SCM commands.

最简单的TCP协议栈，只包括ICMP,ARP,TCP/IP等实用功能

编写一个延时1MS子程序根据题目选择是定时还是记数状态，本题选择记数状态。然后根据延时1MS计算出计时器的初值是E0H（高8位）18H（低5位）。最后编写算法，对T0初始化，利用T0的中断TF0调用中断处理程序。-prepared a delay rungs subroutine under the topic chosen is not a time to memorize numbers or state of mind of the few options that state. According to delay timer rungs calculate the initial value is E0H (high 8) 18H (Low 5). Preparation of the final algorithm, the T0 initialization, interrupt the use of T0 TF0 call interrupt handling procedures.
