pic18f452 TMR1的RTC功能——秒信号发生器(pic18f452 TMR1 the RTC function- second signal generator)

这本C++程序设计书籍由清华大学郑莉所编写是目前C++程序入门的不错书籍。(This C++ programming books written by Tsinghua University Zheng Li is a good introductory book C++ program.)

大多数自行车速度表工作通过使用霍尔效应传感器固定在自行车前叉。磁铁是附加到前轮上的辐条之一,它将与霍尔效应开关一次革命的车轮。速度计监测传感器计数轮革命。如果知道车轮的直径,距离可以很容易地计算如果你知道有多少革命的车轮。此外,如果时间完成革命,平均速度也可以计算出来。 对于这个问题,您将编写一个程序来确定总距离(英里)和平均速度(英里每小时)考虑到车轮直径,革命的数量和总时间的旅行。你可以假定前轮从未离开地面,并没有下滑或打滑。(Most bicycle speedometers work by using a Hall Effect sensor fastened to the front fork of the bicycle. A magnet is attached to one of the spokes on the front wheel so that it will line up with the Hall Effect switch once per revolution of the wheel. The speedometer monitors the sensor to count wheel revolutions. If the diameter of the wheel is known, the distance traveled can be easily be calculated if you know how many revolutions the wheel has made. In addition, if the time it takes to complete the revolutions is known, the average speed can also be calculated. For this problem, you will write a program to determine the total distance traveled (in miles) and the average speed (in Miles Per Hour) given the wheel diameter, the number of revolutions and the total time of the trip. You can assume that the front wheel never leaves the ground, and there is no slipping or skidding.)

模拟系统的屏幕键盘操作，VS2010平台开发，很好的学习模拟按键教材。(Screen keyboard simulation system, VS2010 platform development, good learning materials analog button.)

包含proteus仿真文件及c语言程序，在开发板上进行过运行。利用双色LED显示电路，和四位静态数码管显示电路模拟十字路口交通信号灯。4位LED数码管显示时间，双色LED灯显示红绿灯状态。熟悉交通信号灯控制逻辑。设计一个十字路口的交通灯控制电路，要求南北方向和东西方向两个交叉路口的车辆交替运行。每次绿灯变红灯时,要求黄灯先亮3S,才能变换运行车辆。东西方向、南北方向车道除了有红、黄、绿灯指示外，每一种灯亮的时间都用数码管显示器进行显示（采用倒计时的方法）。考虑到特殊车辆情况，设置紧急转换开头。(It contains proteus simulation file and C language program. It has been run on the development board. Two-color LED display circuit and four-bit static digital tube display circuit are used to simulate traffic lights at intersections. Four-bit LED digital tube display time, two-color LED lights show the status of traffic lights. Familiar with traffic signal control logic. Design a traffic light control circuit at the intersection, which requires the vehicles running alternately in the north-south direction and the East-West direction. Every time the green light turns red, the yellow light is required to turn on 3S before changing the running vehicle. In addition to the red, yellow and green lights in the east-west and North-South lanes, the time of each kind of light is displayed by digital tube display (countdown method). Considering the special vehicle situation, set up the emergency switch start.)
