拿到這本教程您首先就會想，什么是IAP教學(xué)法？是不是一種什么全新的教學(xué)方法？當(dāng)然不是，我可沒那么大的本事，其實(shí)這只是我杜撰的一個(gè)新名詞，意思就是IN APPlications PROGRAN（在應(yīng)用中編程），當(dāng)然這只是針對單片機(jī)教學(xué)，說法是否正確，還得您說了算。

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.

學(xué)習(xí)單片機(jī)總結(jié)寶典 基于本人學(xué)習(xí)單片機(jī)的痛苦經(jīng)歷，特編寫本教程，以此獻(xiàn)給廣大 的單片機(jī)初學(xué)者，希望您能從中受益。 作者提示：本教程乃最通俗易懂之單片機(jī)教材也，如果您還是看 不懂，請千萬不要涉足此行，以免誤入歧途，耽誤您的前程*_* 拿到這本教程您首先就會想，什么是 IAP 教學(xué)法？是不是一種什么全新的教學(xué)方法？當(dāng)然不是， 我可沒有那么大的本事，其實(shí)這只是我杜撰的一個(gè)新名詞，意思就是In APPlications Program（在應(yīng) 用中編程）,當(dāng)然這只是針對單片機(jī)教學(xué)，說法是否正確，還得您說了算。 至于為什么要提這種說法，那我倒想說幾句。大家都知道，學(xué)習(xí)電子技術(shù)是一件非常無聊和枯燥 的事情，為什么會有這種想法，就是因?yàn)槲覀儌鹘y(tǒng)的教學(xué)方法只重理論而忽略了實(shí)踐，要一個(gè)人記住那 些空洞而有無聊的理論知識實(shí)在不是一件容易的事，好在我們總算熬過來了，不管如何，也多多少少的 學(xué)習(xí)了一些電子基礎(chǔ)知識。 接下來我們應(yīng)該進(jìn)一步掌握些什么知識呢，凡涉足此行的朋友都知道，那就是單片機(jī)。不過這可 不是一件容易的事，倒不是因?yàn)閱纹瑱C(jī)很難學(xué)，而實(shí)在是我們身邊很難找到一本專為單片機(jī)入門者而編 寫的教材。翻一下傳統(tǒng)的單片機(jī)教材，都好象是為已經(jīng)懂單片機(jī)的人而寫的，一般總是以單片機(jī)的結(jié)構(gòu) 為主線，先講硬件原理，然后是指令，接著講軟件編程，再是系統(tǒng)擴(kuò)展和外圍器件，最后舉一些實(shí)例（隨 便說一點(diǎn)：很多書中的實(shí)例都是有錯(cuò)誤的），很少涉及單片機(jī)的基礎(chǔ)知識，如果按照此種學(xué)習(xí)方法，想 進(jìn)行產(chǎn)品開發(fā)，就必須先把所有的知識全部掌握了才可以進(jìn)行實(shí)際應(yīng)用。孰不知，單片機(jī)不象模擬電路 和數(shù)字電路那樣，只要搞懂了電路原理，再按照產(chǎn)品要求設(shè)計(jì)好相應(yīng)的電路就可以了。它是一種以簡單 的硬件結(jié)構(gòu)，復(fù)雜而有靈活的軟件系統(tǒng)來完成設(shè)計(jì)的通用性產(chǎn)品，不同的設(shè)計(jì)者只會使用其不同的功能， 幾乎沒有人會把它的全部指令都使用起來，所以學(xué)習(xí)使用單片機(jī)只能靠循序漸進(jìn)的積累，而不可能先把 它全部掌握了再去做產(chǎn)品開發(fā)（當(dāng)然天才就例外了*_*）。
