我这么写对吗？求大神帮忙指导一下。
u8  ADXL345_Init(void)
{
      SPI1_Init();                                                       //初始化SPI总线
      if(SPI1_ReadWriteByte(DEVICE_ID)==0XE5)       //读取器件ID
      {
      SPI_ADXl345_CS=0;
            SPI1_ReadWriteByte(DATA_FORMAT);       //低电平中断输出，13位全分辨率，输出数据右对齐，16g量程
            SPI1_ReadWriteByte(0X2B);
      SPI1_ReadWriteByte(BW_RATE);             //数据输出速度为100HZ
            SPI1_ReadWriteByte(0x0A);
      SPI1_ReadWriteByte(POWER_CTL);       //l链接使能，测量模式
            SPI1_ReadWriteByte(0x28);
      SPI1_ReadWriteByte(INT_ENABLE);       //不使用中断
               SPI1_ReadWriteByte(0x00);
      SPI1_ReadWriteByte(OFSX);
            SPI1_ReadWriteByte(0x00);
      SPI1_ReadWriteByte(OFSY);
            SPI1_ReadWriteByte(0x00);
      SPI1_ReadWriteByte(OFSZ);
      SPI1_ReadWriteByte(0x00);
      SPI_ADXl345_CS=1;
            return 0;
      }
      return 1;
}
