i2c eprom 在wince读取是成功的，但是写入就不成功

test2440 写入 00-ff  wince下我写测试程序读出正确 用官方wince测试程序读取正确 ，但是用官方wince测试程序写入就失败 我自己写的程序也失败 （读出来不对）
for (i=0;i<16;i++)
    {

    
        memset(&IIC_AddressData, 0, sizeof(I2C_IO_DESC));
      
        IIC_AddressData.SlaveAddr=0xa0;
        IIC_AddressData.Data = inbuf;
        IIC_AddressData.WordAddr = 16*i;
        IIC_AddressData.Count = 16;

        {
            Ret = DeviceIoControl(h_I2C,IOCTL_I2C_WRITE, &IIC_AddressData, sizeof(I2C_IO_DESC), OutputBuf,16,&ReadBytes, NULL);
        }
        Sleep(20);
        
        if(Ret == TRUE)
            ;//MessageBox(_T("写AT24LC08成功！"));
        else
            MessageBox(_T("写AT24LC08失败！"));
    }
    for (i=0;i<1;i++)    
    {
        memset(&IIC_AddressData, 0, sizeof(I2C_IO_DESC));

        IIC_AddressData.SlaveAddr = 0xa1;            //READ
        IIC_AddressData.WordAddr = 0;        //start addr
        IIC_AddressData.Data = outbuf;
        IIC_AddressData.Count = 256;

        {
            Ret = DeviceIoControl(h_I2C,IOCTL_I2C_READ, &IIC_AddressData, sizeof(I2C_IO_DESC), OutputBuf, 256,&ReadBytes, NULL);
        }

        if (!ReadBytes)
        {
            MessageBox(TEXT("IIC read single data failed !"));
        }

补充一下 在linux下测试也是成功的

没人？？！！！

是啊，我试着也试这样子，eep 根本写不进去。 楼上 留下qq 交流一下吧

搞了2天了，一点头绪都没有

int CEeprom::WriteData( PUCHAR bData, int iSize)
{
    memset(&IIC_AddressData, 0, sizeof(I2C_IO_DESC));
    IIC_AddressData.SlaveAddr = 0xa0;            //WRITE
    IIC_AddressData.WordAddr = m_StartAddr;        //start addr
    IIC_AddressData.Data = bData;
    IIC_AddressData.Count = iSize;
    for(int i = 0; i < (int)iSize; i++)
        {
            printf("%c\n",IIC_AddressData.Data);
        }
    int Ret = DeviceIoControl(hI2C,IOCTL_I2C_WRITE, &IIC_AddressData, sizeof(I2C_IO_DESC), OutputBuf,iSize,&ReadBytes, NULL);
    if(Ret == true)
        printf("写AT24LC08成功！\n");
    else
        printf("写AT24LC08失败！\n");
    return Result;
}

int CEeprom::ReadData(PUCHAR bData, int iSize)
{
    memset(&IIC_AddressData, 0, sizeof(I2C_IO_DESC));
    IIC_AddressData.SlaveAddr = 0xa1;            //READ
    IIC_AddressData.WordAddr = m_StartAddr;        //start addr
    IIC_AddressData.Data = bData;
    IIC_AddressData.Count = iSize;
    DeviceIoControl(hI2C,IOCTL_I2C_READ, &IIC_AddressData, sizeof(I2C_IO_DESC), OutputBuf, iSize,&ReadBytes, NULL);
    if (!ReadBytes)
    {
        printf("IIC read single data failed !");
    }
    else
    {
        for(int i = 0; i < (int)ReadBytes; i++)
        {
            printf("%c\n",bData);
        }
    
    }
    return Result;
}


可以读但是写进去的怎么是乱码呀?用开发板提供的I2C-EEPROM来写进去然后用自己写的上面的一段代码来读是对的，但是按照写进去就是乱码！是怎么回事呢？
