There are many different (and often confusing) terms associated
with clock-based devices. This application note attempts
to clarify these terms, and hence serves as a comprehensive
reference on clock terminology. This application note can be
divided into two sections. The first section describes and distinguishes
between various clock sources available today.
The second section defines and distinguishes between various
parameters used to describe clocks. This section also provides methods of measuring some of these parameters.

请将OpenPet.ico
放在c盘文件下
当然你也可以放在程序目录，那就要修改程序
将private Icon img = new Icon(@"C:OpenPet.ico")
改为private Icon img = new Icon("OpenPet.ico") -request OpenPet.ico on c disk Document Of course, you can be put on the directory. it is necessary to revise procedures to private Icon img = new Icon (@ "C : OpenPet.ico ") to private Icon img = new Icon (" OpenPet.ico ")

当前LCM的主流接口有并口和串口。并口引脚多，产生串扰，串口则没有诸如此类的缺点。SPI作为串口家族的一员，具有高速同步、芯片管脚少和信号稳定不产生串扰等优点，越来越受到开发人员的青睐。但是，具有SPI的LCM并不是毫无缺点的，市场上以COG(chip on glass)方式封装的LCM大都是基于单工方式传输的，这将给开发带来了非常大的麻烦。本文主要论述基于单工SPI的GUI开发方案，详细地分析了基于单工SPI的GUI的开发开台，论述并分析在GUI开发过程中遇到的问题，最后提出增加虚拟LCD的方案解决这个问题。-err

pcf8951芯片，有四一/ D输入通道：AD1、AD2，AD0，3，2…
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.
