拿到这本教程您首先就会想,什么是IAP教学法?是不是一种什么全新的教学方法?当然不是,我可没那么大的本事,其实这只是我杜撰的一个新名词,意思就是IN appliCations PROGRAN(在应用中编程),当然这只是针对单片机教学,说法是否正确,还得您说了算。

The SN65LBC170 and SN75LBC170 aremonolithic integrated circuits designed forbidirectional data communication on multipointbus-transmission lines. Potential appliCationsinclude serial or parallel data transmission, cabledperipheral buses with twin axial, ribbon, ortwisted-pair cabling. These devices are suitablefor FAST-20 SCSI and can transmit or receivedata pulses as short as 25 ns, with skew lessthan 3 ns.These devices combine three 3-state differentialline drivers and three differential input linereceivers, all of which operate from a single 5-Vpower supply.The driver differential outputs and the receiverdifferential inputs are connected internally to formthree differential input/output (I/O) bus ports thatare designed to offer minimum loading to the buswhenever the driver is disabled or VCC = 0. Theseports feature a wide common-mode voltage rangemaking the device suitable for party-lineappliCations over long cable runs.

学习单片机总结宝典 基于本人学习单片机的痛苦经历,特编写本教程,以此献给广大 的单片机初学者,希望您能从中受益。 作者提示:本教程乃最通俗易懂之单片机教材也,如果您还是看 不懂,请千万不要涉足此行,以免误入歧途,耽误您的前程*_* 拿到这本教程您首先就会想,什么是 IAP 教学法?是不是一种什么全新的教学方法?当然不是, 我可没有那么大的本事,其实这只是我杜撰的一个新名词,意思就是In appliCations Program(在应 用中编程),当然这只是针对单片机教学,说法是否正确,还得您说了算。 至于为什么要提这种说法,那我倒想说几句。大家都知道,学习电子技术是一件非常无聊和枯燥 的事情,为什么会有这种想法,就是因为我们传统的教学方法只重理论而忽略了实践,要一个人记住那 些空洞而有无聊的理论知识实在不是一件容易的事,好在我们总算熬过来了,不管如何,也多多少少的 学习了一些电子基础知识。 接下来我们应该进一步掌握些什么知识呢,凡涉足此行的朋友都知道,那就是单片机。不过这可 不是一件容易的事,倒不是因为单片机很难学,而实在是我们身边很难找到一本专为单片机入门者而编 写的教材。翻一下传统的单片机教材,都好象是为已经懂单片机的人而写的,一般总是以单片机的结构 为主线,先讲硬件原理,然后是指令,接着讲软件编程,再是系统扩展和外围器件,最后举一些实例(随 便说一点:很多书中的实例都是有错误的),很少涉及单片机的基础知识,如果按照此种学习方法,想 进行产品开发,就必须先把所有的知识全部掌握了才可以进行实际应用。孰不知,单片机不象模拟电路 和数字电路那样,只要搞懂了电路原理,再按照产品要求设计好相应的电路就可以了。它是一种以简单 的硬件结构,复杂而有灵活的软件系统来完成设计的通用性产品,不同的设计者只会使用其不同的功能, 几乎没有人会把它的全部指令都使用起来,所以学习使用单片机只能靠循序渐进的积累,而不可能先把 它全部掌握了再去做产品开发(当然天才就例外了*_*)。
