我的AT24C256只能读写一个，页读写就只能读写第一个成功而已：代码如下：void I2C_Read_AT24C64(uint WAddrH,uint WAddrL,uint RNum){ //??WAddrH,WAddrL???×???·??????????RNum??×???
uchar Cnt; //????×??à32??×???
uchar ACK;
uchar recvie_count=0;
I2C_SDA_OUT(); 
I2C_SDA_IN();
  IIC_Start(); //?????¨??
  do{
  IIC_Send(0xa0);//AT24C64???????·
             ACK = IIC_Wait_Ack();
        }while(ACK);
do{
IIC_Send(WAddrH); //???????·????5??
     ACK = IIC_Wait_Ack();
}while(ACK);
do{
IIC_Send(WAddrL); //???????·????8??
     ACK = IIC_Wait_Ack();
}while(ACK);
IIC_Start(); //?????????¨??
do{
IIC_Send(0xa1); //AT24C64???????·
     ACK = IIC_Wait_Ack();
}while(ACK);
for(Cnt = 0;Cnt < RNum;Cnt ++){ //???·????RNum??×???

RD24C64[Cnt]=IIC_Read();
recvie_count=RD24C64[Cnt];
printf("?????????????? ");
printf("%c ",recvie_count);
if(Cnt != RNum - 1)
I2C_ACK_Send(0);
// IIC_Ack();
}
I2C_ACK_Send(1); //????×??ó????×??????????ó??·?????
// IIC_NAck();
IIC_Stop(); //?¨???á??
// return 0;
}
