本人所做项目中用51系列单片机(STC89C58RD)对OCMJ8*15B液晶屏进行数据写操作时所写的配套源代码,可以直接在keil7.0以上的版本中嵌入开发！应该说本程序有很高的实用价值（本人开发的产品已应用于实际工业控制中）-I conducted a series of 51 projects using SCM (STC89C58RD)* 15 OCMJ8 B LCD screen for data write operation written by supporting source code, keil7.0 directly on the above versions embedded development! It should be said that this program has high practical value (I development of the product has been used in practical industrial control)

基于89S52单片机的4位LED显示，定时程序，定时器初值可以在程序中修改。-89S52-based MCU four LED display, the regular procedures Initial timer in the process of change.

此程序为AD9850（DDS）直接数字频率合成器C语言源码。用125M的有源晶振，频率无失真输出可达到40M。该程序包括FYD12864LCD显示程序加4X4矩阵键盘扫描，可步进1M，1K，和任意频率输入。及相位设置。-This procedure for the AD9850 (DDS) Direct Digital Frequency Synthesizer C language source code. With 125M active crystal, the frequency output can be achieved without distortion 40M. The process includes the display program FYD12864LCD plus 4X4 matrix keyboard scanning, may be stepping 1M, 1K, and arbitrary frequency input. And phase settings.

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.
