万年历挂钟智能系统设计开发环境为ICC,可以编译成汇编,直接下栽到嵌入式avr单片机进行控制-calendar wall clock intelligent system design and development environment for the ICC, can compile a compendium, Embedded directly to the downward avr microprocessor control

计时器，５１源码，芯片是７7E58,精度是10uS，上升沿，下降沿，脉宽都可以测量，８路同时测量，１０个数据存储，指标就这样了-Timer, 51 source code, chip is 77E58, precision is 10uS, rising edge, falling edge, pulse width can be measured, 8-channel simultaneous measurement, 10 data storage, so the indicators

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
