| 摘 要： | I2C总线是一种用于IC器件之间连接的二线制总线。I2C增加了高速模式,其速度可达3.4Mbits/s。它使得I2C总线能够支持现有以及将来的高速串行传输应用,例如EEPROM和Flash存储器。而AT24C02是美国爱特梅尔(ATMEL)公司生产的最新串行CMOS EEPROM芯片,支持I2C总线协议。数字信号处理器(DSP)具有丰富的接口,将DSP的多通道缓冲串行接口(简称MCBSP)配置成GPIO(一般通用输入输出口),能够按照I2C协议进行工作。

| Abstract: | I2C main bus is binary bus used to connect IC component.High speed mode is added in I2C,its speed is high up to 3.4Mbits/s.thus I2C main bus can support application of high speed serial transport now and in future,for example,EEPROM and Flash component.AT24C02 is produced by ATMEL.It is the newest serial CMOS EEPROM chip,and it supports I2C main bus protocol.Digital Signal Process(DSP) has rich interface,we can configure MCBSP of DSP into GPIO,then it can work accord to I2C protocol. |
