1、学习Proteus的使用，

2、学习并掌握编译器Keil C环境下做51的系统开发

3、进一步学习时钟的算法，会使用硬件实现此算法；

4、了解基于RTOS上的多任务分时使用CPU，掌握任务的创建、删除、等待以及任务之间的同步等基本的多任务程序设计方法、掌握操作系统的基本原理。

-1, to learn the use of Proteus, 2, to learn and master the Keil C compiler environment do 51 System Development 3, further study clock algorithms, will use the hardware to achieve this algorithm　4, understanding RTOS based on the time-sharing the use of multi-tasking CPU, have the task to create, delete, waiting, as well as the synchronization between the mandates of the basic procedures for multi-tasking design method, grasp the basic principles of the operating system.
