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的编程技巧 本章介绍局部变量、全局变量、属性节点和其他一些有助于提高编程技巧的问题，恰当地运用这些技巧可以提高程序的质量。 ８．１ 局部变量 严格的语法尽管可以保证程序语言的严密性，但有时它也会带来一些使用上的不便。在labview这样的数据流式的语言中，将变量严格地分为控制器（Control）和指示器（Indicator），前者只能向外流出数据，后者只能接受流入的数据，反过来不行。在一般的代码式语言中，情况不是这样的。例如我们有变量a、b和c，只要需要我们可以将a的值赋给b，将b的值赋给c等等。前面所介绍的labview内容中，只有移位积存器即可输入又可输出。另外，一个变量在程序中可能要在多处用到，在图形语言中势必带来过多连线，这也是一件烦人的事。还有其他需要，因此labview引入了局部变量。

为解决现Z-Stack定位程序代码量大，结构复杂等问题，提出一种基于TinyOS的CC2430定位方案。在分析TinyOS组件架构基础上，设计实现盲节点、锚节点与汇聚节点间的无线通信以及汇聚节点与PC机的串口通信。在此基础上实现PC对各锚节点RSSI（Received Signal Strength Indicator）寄存器值的正确读取，确定实验室环境下对数-常态无线传播模型的具体参数，并采用质心算法来提高定位精度。实验显示，在由四个锚节点组成的4.8×3.6 m2矩形定位区域中，通过RSSI质心定位算法求得的盲节点坐标为（2.483 1，1.018 5），实际坐标为（2.40，1.20），误差为0.199 6 m，表明较好地实现对盲节点的定位。

基于药物治疗在临床治疗中的重要性,分析目前服药提醒装置存在的不足,以STM32F103VET6单片机为控制核心,设计了一种多功能电子药箱。该系统包括显示模块、语音模块和数据存储模块。显示模块通过触摸屏电路和LED指示灯电路,与语音模块相配合,实现了服药提醒及指导的功能;数据存储模块通过EEPROM存储电路,能够实现掉电时服药信息不丢失的功能。并且为了实现电子药箱的智能化控制,开发了手机APP,两者之间可通过WIFI进行数据通信。经测试,该药箱能够有效地帮助慢性病患者按时、定量、正确服用药物,适合在家庭中推广使用,具有较高的应用价值和实践意义。Based on the importance of drug therapy in clinical treatment, this paper analyzes the shortcomings of current drug reminder devices, and designs a multi-function electronic medicine box with STM32 F103 VET6 microcontroller as the control core. The system includes a display module, a voice module, and a data storage module. The display module cooperates with the voice module through the touch screen circuit and the LED Indicator circuit to realize the function of reminding and guiding the medicine;the data storage module can realize the function of not losing the medication information when the power is off through the EEPROM storage circuit.After testing, the medicine box can effectively help chronic diseases patients to take drugs on time, in a quantitative and correct manner,and is suitable for popularization in the family, and has high application value and practical significance.
