Description: 本程序使用MSP430F149控制IIC总线EEProm AT24C02；MCU的通用输入输出(GPIO)端口P1.2、P1.3 与AT24C02 的SCL、SDA端口相连接构成I2C总线，因为MSP430F149 内部没有专用的I2C接口电路，所以只能用IO端口来模拟I2C时序从而实现对EEPROM的读写操作。从图 3.3 中我们可以看到EEPROM地址选择端口A0~A2 都外接低电平，所以进行I2C通信时，EEPROM的从机地址是唯一的，即A0~A2 所对应的地址控制位均为 0。
因为AT24C0X(X=1,2,4,8,16)系列芯片的管脚是兼容的，所以用户也可以自行更换其他型号的芯片，无需改动任何硬件结构，只需注意器件地址和存储空间寻址模式的变化，相应地修改软件程序即可。
