飞思卡尔单片机MC9SDG128B的计数器源程序，用于速度测量中脉冲个数统计，可以实现速度测量，路程测量等。-Freescale" s single-chip counters MC9SDG128B source for the pulse velocity measurement in the number of statistics, can achieve the speed measurement, distance measurement.

注:protel电路图 1.INPUT12为高压气压和低压压传感器输入端. 2.OUTPUT为充气输出控制端. 3.当高低压有接地信号时,电机正转,气阀打开. 4.INPUT2低气压时有信号时,充气OUTPUT输出,充气电机转. 5.RS1与RS2是调节阀门距离用地 6.RS3是与气阀电机同步时,是气阀电机的转动圈数传感器. 7.RS4是调节延时时间用地-Note: protel circuit 1.INPUT12 and low-voltage high-pressure pneumatic pressure sensor input. 2.OUTPUT output control for the inflated side. 3. When the high and low pressure have a grounding signal when the motor is transferred, the valve opens. 4.INPUT2 low pressure when there is signal output OUTPUT inflatable, inflatable motor switch. 5.RS1 and RS2 is the regulator valve from the land 6.RS3 synchronous motor with the valve, the valve motor is rotating circle the number of sensors. 7.RS4 delay time to regulate land

本文介绍了一种电子密码锁的实现。该电子密码锁采用1一wire总线芯片Ds2401作为密匙，锁体采用高可靠性的单片机PIC16c63来完成密码识别和开锁控制，用I2C总线接口的EEPROM 芯片AT24c02来完成密码的存储和修改，可 掉电保存密码。整个系统安全可靠，稳定性高。-This paper introduces an electronic code lock realize. The electronic locks used one chip one wire bus Ds2401 as key, lock body for high reliability PIC16C63 microcontroller identification and password to complete the unlock control, with I2C bus interface EEPROM chip AT24C02 to complete the password storage and revised down to save the password. The entire system is safe and reliable, high stability.
