SPI总线的学习

本模拟I2C软件包包含了I2C操作的底层子程序，使用前要定义好SCL和SDA。在标准8051模式(12 Clock)下,对主频要求是不高于12MHz-The simulation package includes I2C bottom I2C operation subroutine, before the definition of a good use of SCL and SDA. 8051 in standard mode (12 Clock), the requirements for the frequency is higher than 12MHz

此资料里有单片机的仿真实例。本人试了非常有用。希望此资料对大家有所帮助！-This information, there are examples of microcomputer simulation. I tried very useful. I hope that this information be helpful to everyone!

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.
