介绍了一种基于MSP430系列单片机和ADXL203加速度传感器的数字式倾角仪,它不仅可以实现水平度检测,而且可以测量00~3600范围内的任意倾角,分辨率可达O.1。。此外,由于该倾角仪输出为数字结果,因此它也可以与其他的数字设备结合起来,组合成一个功能更加强大的仪器。该数字倾角仪可广泛应用于建筑、机械、道路、桥梁、石油、煤矿和地质勘探等各种需要测量重力参考系下倾角的场合。关键词:MSP430F133单片机;力敏传感器;ADXL203加速度计;角度测量 Abstract:This paper presents a new style digital inclinometer which is developed on the basis of the MSP430F133 MCU and the ADXL203 dual axis aeeelerometer.This inclinometer not only can test levelness,but also can measure any angle between 0。and 360。with an accuracy of 0.1 O.In addition,its output is a digital result,which makes it possible to integrate itself with other digital devices to form a more functional unit.This inclinometer can be widely used in any construction site,oil field,coal-mine or geologic survey and SO on where it will provide the working people with convenience to measure any angles.Key words:MSP430F133 MCU;force sensor;ADXL203 accelerometer;angle measurement

为了能够满足基站易于选址、优质快速的建站要求和易维护、低成本、高可靠的运行要求,本文对以方舱来实现一体化结构基站做出一番探讨。从系统设计的观点阐述了移动通信高性能基站天线设计的几个关键问题,介绍了智能天线技术在基站中的应用,并且用HFSS软件仿真了一种新型的对称阵子天线,该天线驻波比小于2的带宽可以达到60%,具有良好的宽频带特性。 Abstract: In order to meet the station construction requirement of easy site selection and fast base station, and meet the operational requirement of easy maintenance, low cost and high reliability, this paper discussed the unified architecture base station using shelter. Several key problems of high performance mobile communication base station antenna were illustrated from the view of system design, the application of smart antenna in base station was also introduced. And a novel dipole antenna was simulated by using HFSS, the VSWR of the antenna is less than 2, and the bandwidth was reach to 60%. So it has good broadband properties.

CBC下写的串口编程,API函数实例 I wish this site had been around when I was trying to figure out how to make serial communications work in Windows95. I, like many programmers, was hit with the double-whammy of having to learn Windows programming and Win95 serial comm programming at the same time. I found both tasks confusing at best. It was particularly frustrating because I had, over the years, written so much stuff (including lots of serial comm software) for the DOS environment and numerous embedded applications. Interrupt driven serial comm, DMA transfer serial comm, TSR serial comm, C, assembler, various processors... you name it, it had written it. Yet, everything I knew seemed upside-down in the message-driven-callback world of Windows.
