一个单片机字码编程的好工具，解决了汉字字码编程的麻烦

利用STC单片机实现软件模拟全双工串口的程序，只用一个定时器，消耗系统资源很少。-using SCM software simulation of the full-duplex serial procedures, only a timer, depletion of scarce resources system.

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

这是一个实现单片机串口通讯的简单例子,对初学者是很有用的-This is a microcontroller serial communication to achieve a simple example

这是f040与2401连接后，进行通信的程序。已经调试通过了 仅供大家参考 第一次传 不好的习惯请大家指正 -This is connected with the 2401, the communications procedures. Debugging has been adopted only refer to the first-bad habit of correcting Thank you, please

电容入门知识 电容就是两块导体中间夹着一块绝缘体构成的电子组件，就像三明治一样。电容是电子设备中最基础也是最重要的组件之一。电容的产量占全球电子元器件产品（其它的还有电阻、电感等）中的40 以上。基本上所有的电子设备，小到闪盘、数码相机，大到航天飞机、火箭中都可以见到它的身影。-Introduction to knowledge capacitance capacitor is two conductors in the middle of holding a piece of electronic components consisting of an insulator, like, like sandwiches. Capacitance is the most basic electronic equipment is one of the most important components. Capacitance of the total global production of electronic components products (there are other resistors, inductors, etc.) in more than 40 . Basically, all the electronic equipment, small enough to flash drives, digital cameras, as large as the space shuttle, rockets can be seen in both figure it.
