The MAX3243E device consists of three line drivers, five line receivers, and a dual charge-pump circuit with±15-kV ESD (HBM and IEC61000-4-2, Air-Gap Discharge) and ±8-kV ESD (IEC61000-4-2, Contact Discharge)protection on serial-port connection pins. The device meets the requirements of TIA/EIA-232-F and provides theelectrical interface between an asynchronous communication controller and the serial-port connector. Thiscombination of drivers and receivers matches that needed for the typical serial port used in an IBM PC/AT, orcompatible. The charge pump and four small external capacitors allow operation from a single 3-V to 5.5-Vsupply. In addition, the device includes an always-active noninverting output (ROUT2B), which allowsapplications using the ring Indicator to transmit data while the device is powered down. The device operates atdata signaling rates up to 250 kbit/s and a maximum of 30-V/ms driver output slew rate.

第八章 labview的編程技巧 本章介紹局部變量、全局變量、屬性節(jié)點(diǎn)和其他一些有助于提高編程技巧的問題，恰當(dāng)?shù)剡\(yùn)用這些技巧可以提高程序的質(zhì)量。 ８．１ 局部變量 嚴(yán)格的語法盡管可以保證程序語言的嚴(yán)密性，但有時它也會帶來一些使用上的不便。在labview這樣的數(shù)據(jù)流式的語言中，將變量嚴(yán)格地分為控制器（Control）和指示器（Indicator），前者只能向外流出數(shù)據(jù)，后者只能接受流入的數(shù)據(jù)，反過來不行。在一般的代碼式語言中，情況不是這樣的。例如我們有變量a、b和c，只要需要我們可以將a的值賦給b，將b的值賦給c等等。前面所介紹的labview內(nèi)容中，只有移位積存器即可輸入又可輸出。另外，一個變量在程序中可能要在多處用到，在圖形語言中勢必帶來過多連線，這也是一件煩人的事。還有其他需要，因此labview引入了局部變量。

為解決現(xiàn)Z-Stack定位程序代碼量大，結(jié)構(gòu)復(fù)雜等問題，提出一種基于TinyOS的CC2430定位方案。在分析TinyOS組件架構(gòu)基礎(chǔ)上，設(shè)計(jì)實(shí)現(xiàn)盲節(jié)點(diǎn)、錨節(jié)點(diǎn)與匯聚節(jié)點(diǎn)間的無線通信以及匯聚節(jié)點(diǎn)與PC機(jī)的串口通信。在此基礎(chǔ)上實(shí)現(xiàn)PC對各錨節(jié)點(diǎn)RSSI（Received Signal Strength Indicator）寄存器值的正確讀取，確定實(shí)驗(yàn)室環(huán)境下對數(shù)-常態(tài)無線傳播模型的具體參數(shù)，并采用質(zhì)心算法來提高定位精度。實(shí)驗(yàn)顯示，在由四個錨節(jié)點(diǎn)組成的4.8×3.6 m2矩形定位區(qū)域中，通過RSSI質(zhì)心定位算法求得的盲節(jié)點(diǎn)坐標(biāo)為（2.483 1，1.018 5），實(shí)際坐標(biāo)為（2.40，1.20），誤差為0.199 6 m，表明較好地實(shí)現(xiàn)對盲節(jié)點(diǎn)的定位。
