嵌入式系统已经广泛应用于各个科技领域和日常生活的每个角落，由于其本身的特性，使得我们很难发现它的存在。甚至一些从事嵌入式系统开发的科技人员也只知单片机，不知道嵌入式系统。本节从嵌入式系统的定义开始，阐述嵌入式系统的含义、特点等，以使读者加深对嵌入式系统的理解。 -Embedded systems are widely used in various fields of science and technology and everyday life in every corner, due to its own characteristics, making it very difficult for us to discover its existence. Embedded systems and even some involved in the development of scientific and technical personnel are also only single-chip, embedded systems do not know. This section from the beginning of the definition of embedded systems, embedded systems on the meaning, characteristics and so on, in order to enable readers to deepen their understanding of embedded systems.

设计程序使一个LED发光管以0.6秒为周期闪烁，即发光管每0.3秒点亮或熄灭一次。 分析题目要求，主要涉及两方面的操作，即控制LED发光管的亮灭以及定时0.3秒。对于LED发光管，只用一个IO就可以控制了（例如使用IOA0）；而对于0.3秒定时，我们可以利用TimerA定时器轻易地实现。-The design process of a LED to LED blinking 0.6 seconds for the cycle, that is, every 0.3 seconds LED lit or extinguished once. Analysis of the subject requirements, mainly related to two aspects of the operation, that is, control LED LED light out as well as the timing of 0.3 seconds. The LED light-emitting tube, only one can control the IO (such as the use of IOA0) and for 0.3 seconds from time to time, we can use to easily achieve TimerA timer.
