开发环境：Keil
光电开关作计数
每转10个脉冲，用中断计数。
可设定停机数。
可以正反转计数
工作稳定
可快速预置4组数值
可循环在两组设定数之关来回计数-Electric Winder Counter (circuit and the source of code). A brief description in December 2004 to do small projects, 40 to come to Taiwan machine, has been in the workshop to run 3 years. OK! <Electric winding machine count controller> include the compilation of source code, code development environment burner: Keil photoelectric switch for counting 10 pulses per revolution, using interrupt count. Can set down a few. The stability of positive work can count fast numerical preset 4 can be recycled in the two groups set the number of customs return count (around the servo motor the most convenient!)

Description: 数字频率计的设计可以分为测量计数和显示。其测量的基本原理是计算一定时间内待测信号的脉冲个数，这就要求由分频器产生标准闸门时间信号，计数器记录脉冲个数，由控制器对闸门信号进行选择，并对计数器使能断进行同步控制。控制器根据闸门信号确定最佳量程。-The design of digital frequency meter can be divided into measurement and display count. The basic principle of its measurement is calculated under test signal within a certain period of time the number of pulses, which have a standard requirement by the divider gate time signal pulse counter records the number of signals from the controller to choose the gates and counters to make off synchronous control can be carried out.Controller based on the gate signal to determine the optimum range.

Description: Most satellite dish actuators send a series of pulses to indicate their position. By counting pulses the positioner knows where the dish is pointing. It is possible to use a serial port and Linux with RTAI patches in order to count these pulses, thus minimising the external hardware required for a positioner. The zip contains instructions, circuit diagrams and example code.-Most satellite dish actuators send a series of pulses to indicate their position.

Description: The output from incremental optical encoders and from many other types of measurement devices is known as a “quadrature” signal. A quadrature signal consists of two square waves 90° out of phase. The input channel on our encoder interface board counts the square wave transitions and determines direction by comparing whether channel A is leading channel B or vice-versa. The number of revolutions is determined by dividing the count by the number of pulses per revolution: e.g., 100 counts with a 1000 PPR (Pulses Per Revolution) encoder is equal to 36 degrees. Velocity is computed the same way by counting the number of pulses per second.

Description: 拔河游戏机， 1、 设计一个能进行拔河游戏的电路。 2、 电路使用15个(或9个)发光二极管，开机后只有中间一个发亮，此即拔河的中心点。 3、 游戏双方各持一个按钮，迅速地、不断地按动，产生脉冲，谁按得快，亮点就向谁的方向移动，每按一次，亮点移动一次。 4、 亮点移到任一方终端二极管时，这一方就获胜，此时双方按钮均无作用，输出保持，只有复位后才使亮点恢复到中心。 5、 用数码管显示获胜者的盘数。教学提示: 1、 按钮信号即输入的脉冲信号，每按一次按钮都应能进行有效的计数。 2、 用可逆计数器的加、减计数输入端分别接受两路脉冲信号，可逆计数器原始输出状态为0000，经译码器输出，使中间一只二极管发亮。 3、 当计数器进行加法计数时，亮点向右移；进行减法计数时，亮点向左移。 4、 由一个控制电路指示谁胜谁负，当亮点移到任一方终端时，由控制电路产生一个信号，使计数器停止计数。 5、 将双方终端二极管“点亮”信号分别接两个计数器的“使能”端，当一方取胜时，相应的计数器进行一次计数，这样得到双方取胜次数的显示。 6、 设置一个“复位”按钮，使亮点回到中心，取胜计数器也要设置一个“复位”按钮，使之能清零。-1, design a circuit can be a tug of war game. 2, the circuit using the 15 (or 9) light-emitting diodes, only after the middle of a bright start, namely the center of a tug of war. 3, games, and each side holding a button, rapidly and constantly pressed to produce pulses, who according to fast, to whom the direction of bright spots on the move, every time, bright spots move once. 4, highlights the terminal diode when the move to either party, the party would win, this time the two sides had no role in the button, the output to maintain, and only reset after so bright to restore to the center. 5, digital tube display the number of the winner of the plate. Teaching tips: 1, buttons, signals that the input pulse signal, every time I press the button should be able to effectively count. 2, with reversible counter to add, subtract count input pulse signal, respectively to accept two-way, reversible, the original output of the counter state 0000, via decoder output, so that the middle of an L

Description: 频率的测量实际上就是在1s时间内对信号进行计数，计数值就是信号频率。用单片机设计频率计通常采用两种办法，第一种方法是使用单片机自带的计数器对输入脉冲进行计数；第二种方法是单片机外部使用计数器对脉冲信号进行计数，计数值再由单片机读取。-In the measurement of frequency is actually 1s to count time signal, numerical is signal frequency. Using single-chip microcomputer frequency plan by using two kinds of method, usually the first approach is to use own counter chip counting input pulses, The second method is to use external counter pulse signal count by MCU, numerical read again.
