本电路采用AD698 LVDT信号调理器，包含一个正弦波振荡器和一个功率放大器，用于产生驱动原边LVDT的激励信号。AD698还可将副边输出转换为直流电压。AD8615轨到轨放大器缓冲AD698的输出，并驱动低功耗12位逐次逼近型模数转换器(ADC)。系统动态范围为82 dB，带宽为250 Hz，非常适合精密工业位置和计量应用。
This circuit uses the AD698 LVDT signal conditioner, which includes a sine wave oscillator and a power amplifier to generate the excitation signal that drives the primary LVDT. The AD698 also converts the secondary output to a DC voltage. The AD8615 rail-to-rail amplifier buffers the output of the AD698 and drives a low-power, 12-bit successive approximation analog-to-digital converter (ADC). With a system dynamic range of 82 dB and a bandwidth of 250 Hz, it is ideal for precision industrial location and metrology applications. (2018-08-15, C51, 452KB, 下载17次)
随着居民生活水平的不断提高，自行车不再仅仅是普通的运输、代步的工具，而是成为人们娱乐、休闲、锻炼的首选。这就为自行车的速度里程表的诞生提供了条件,一款经济实惠的速度里程表能够在满足人们最基本的需求下，更好地帮助人们清楚地知道当前的速度、里程等物理量,更好的掌握当前运动状况。
本论文主要阐述一种具有警报功能的自行车的里程表的设计。以AT89C52单片机为核心，A44E霍尔传感器测转数，实现对自行车里程/速度的测量统计，采用24C02实现在系统掉电的时候保存里程信息，并能将自行车的里程数及速度用LED实时显示。
With the continuous improvement of the living standard of the residents, the bicycle is no longer only a common transportation and step tool, but the first choice for people's entertainment, leisure and exercise. This provides the conditions for the birth of a bicycle speedometer. An economical speedometer can better help people know the current speed, mileage and other physical quantities, and better grasp the current sports conditions, to meet the basic needs of the people.
This paper mainly describes the design of a bicycle odometer with alarm function. Taking the AT89C52 single chip as the core, the A44E Holzer sensor measured the rotation number, realized the measurement and statistics of the bicycle mileage / speed, and used 24C02 to save the mileage information when the system dropped the power, and could display the mileage and speed of the bicycle in real time with the LED.

MA803 是基于80C51的高效1-T结构的单芯片微处理器，每条指令需要1~7个时钟信号 (比标准8051快6~7倍)，与8051
指令集兼容。因此在与标准8051有同样的处理能力的情况下，MA803只需要非常低的运行速度，同时由此能很大程度
的减少耗电量。
The efficient 1-T of MA803 is based on 80C51 structure of the single-chip microprocessor, each instruction needs to 1~7 a clock signal (6~7 times faster than standard 8051), and 8051
Instruction set compatible. In the case of the same processing power with the standard 8051, MA803 only needs a very low operating speed, and can greatly
Reduce power consumption. (2016-08-18, C51, 1143KB, 下载2次)

随着科技的不断发展，社会的不断进步，供人们娱乐休闲的工具越来越多，摇摇棒也随之成为一个热点产品。“摇摇棒”是基于人眼视觉暂留原理而产生的,当进行摇动时，由于人的视觉暂留会在发光二极管摇动区域产生一个视觉平面，从而达到在该视觉平面上传达信息的作用。本文介绍了以STC11F02E单片机控制为主控芯片、配合高亮度LED二极管以及水银开关构成简易摇摇棒的设计过程，通过分时刷新32个发光二极管来显示输出文字或图案等信息。
As we all know, the human eye visual persistence phenomenon, because the eye is unresponsive, it enriched the human visual perception.
With the continuous development of science and technology, social progress, offer people entertainment tool more and more, shaking his stick also becomes a hot product. Swing is based on the human visual persistence principle which, when moved, due to the persistence of vision in the light emitting diode shake the region produces a visual plane, in order to achieve the vision plane to convey information about the role of.
