EMC的开发库 是单片机性价比高的选择 提高快速开发-EMC microcontroller development libraries are cost-effective option to enhance rapid development of high

芯片PCF8951共有四个A/D输入通道：AD0，AD1，AD2，AD3,分别与四个电位器(R1,R2,R3,R4)连接，用以调节电位器的输出电压。其中AD0通道既可测量电位器输出电压，也可用于测量从J1插座输入的外接电压，须用开关J2加以选择。J4插座提供由PCF8591输出的时钟方波信号。SAA1064驱动四个数码管显示一路AD转换后得到的数据。-PCF8951 chip, there are four A/D input channels: AD0, AD1, AD2, AD3, respectively, with four potentiometers (R1, R2, R3, R4) connected to regulate the output voltage potential. AD0 channel which can be measured potentiometer output voltage can also be used to measure the input from the J1 socket external voltage, to be used to select switch J2. J4 socket output from the PCF8591 clock square wave signal. SAA1064 drivers of four digital display along after AD conversion data.

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.
