The TRS232E is a dual driver/receiver that includes a capacitive voltage generator to supply TIA/RS-232-Fvoltage levels from a single 5-V supply. Each receiver converts TIA/RS-232-F inputs to 5-V TTL/CMOS levels.This receiver has a typical threshold of 1.3 V, a typical hysteresis of 0.5 V, and can accept ±30-V inputs. Eachdriver converts TTL/CMOS input levels into TIA/RS-232-F levels. The driver, receiver, and voltage-generatorfunctions are available as cells in the Texas Instruments LinASIC™ library.

This application note shows how to write an Inter Integrated Circuit bus driver (I²C) for the Philips P90CL301micro-controller.It is not only an example of writing a driver, but it also includes a set of application interface software routines toquickly implement a complete I²C multi-master system application.For specific applications the user will have to make minimal changes in the driver program. Using the drivermeans linking modules to your application software and including a header-file into the application sourceprograms. A small example program of how to use the driver is listed.The driver supports i.a. polled or interrupt driven message handling, slave message transfers and multi-mastersystem applications. Furthermore, it is made suitable for use in conjunction with real time operating systems, likepSOS+.

This application note demonstrates how to write an Inter Integrated Circuit bus driver (I2C) for the XA-S3 16-bitMicrocontroller from Philips Semiconductors.Not only the driver software is given. This note also contains a set of (example) interface routines and a smalldemo application program. All together it offers the user a quick start in writing a complete I2C system applicationwith the PXAS3x.The driver routines support interrupt driven single master transfers. Furthermore, the routines are suitable foruse in conjunction with real time operating systems.

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(wú)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(duì)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(duì)數(shù)-常態(tài)無(wú)線傳播模型的具體參數(shù)，并采用質(zhì)心算法來(lái)提高定位精度。實(shí)驗(yàn)顯示，在由四個(gè)錨節(jié)點(diǎn)組成的4.8×3.6 m2矩形定位區(qū)域中，通過(guò)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(duì)盲節(jié)點(diǎn)的定位。
