拿到這本教程您首先就會想，什么是IAP教學法？是不是一種什么全新的教學方法？當然不是，我可沒那么大的本事，其實這只是我杜撰的一個新名詞，意思就是IN Applications PROGRAN（在應用中編程），當然這只是針對單片機教學，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.

學習單片機總結寶典 基于本人學習單片機的痛苦經歷，特編寫本教程，以此獻給廣大 的單片機初學者，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 教學法？是不是一種什么全新的教學方法？當然不是， 我可沒有那么大的本事，其實這只是我杜撰的一個新名詞，意思就是In Applications Program（在應 用中編程）,當然這只是針對單片機教學，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，學習電子技術是一件非常無聊和枯燥 的事情，為什么會有這種想法，就是因為我們傳統的教學方法只重理論而忽略了實踐，要一個人記住那 些空洞而有無聊的理論知識實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 學習了一些電子基礎知識。 接下來我們應該進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。不過這可 不是一件容易的事，倒不是因為單片機很難學，而實在是我們身邊很難找到一本專為單片機入門者而編 寫的教材。翻一下傳統的單片機教材，都好象是為已經懂單片機的人而寫的，一般總是以單片機的結構 為主線，先講硬件原理，然后是指令，接著講軟件編程，再是系統擴展和外圍器件，最后舉一些實例（隨 便說一點：很多書中的實例都是有錯誤的），很少涉及單片機的基礎知識，如果按照此種學習方法，想 進行產品開發，就必須先把所有的知識全部掌握了才可以進行實際應用。孰不知，單片機不象模擬電路 和數字電路那樣，只要搞懂了電路原理，再按照產品要求設計好相應的電路就可以了。它是一種以簡單 的硬件結構，復雜而有靈活的軟件系統來完成設計的通用性產品，不同的設計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，所以學習使用單片機只能靠循序漸進的積累，而不可能先把 它全部掌握了再去做產品開發（當然天才就例外了*_*）。
