基于PIC单片机实验装置的研制

随着单片机技术的发展,Microchip公司生产的PIC系列单片机销量已经占据世界8位单片机市场的首位。为了推动PIC单片机教学在中国高校的普及,研制一种基于PIC16F87X的PIC单片机的教学实验装置,主要介绍其设计思想、总体设计方案及基于该装置的实验设计。     

单片机教学改革的探讨

单片机是一们实用性很强课程,目前我国教学主要以51系列单片机为主要芯片进行教学,而实际上单片机的发展已经到了百花齐放的多元化单片机,而且有的单片机系列如PIC、AVR的结构和程序与51系列单片机有所不同,因此本文提出一种新的教学模式和教学手段。     

PIC单片机与PC串行通信的实现

近年来PIC单片机的应用场合越来越多，但有些场合PIC单片机内部串行口不稳定，有些PIC单片机内并没有提供串行口，所以有时串行通信必须通过自己设计的硬件电路和通信软件来实现．利用面向对象的程序设计语言和MSComm控件，使用中的硬件接口电路及源程序，实现了PIC单片机与PC机简洁串行通信．

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?     

只要努力,不要后悔

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.     

浅谈移民问题

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject.     

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.

胡主席在印度,我却在中国

Today, Sunday morning, I sit thinking and typing at my computer. My thoughts are in my homeland, India and my body is in China. The body is here and mind there for a good reason. Mr. Hu is president and I am resident and both are in each other's countries (what a difference the absence of one small letter makes!). Mr. Hu will return in a few days and I will stay on longer.
