int32_t I2C_ReadData(uint8_t RegAddress)
{
int32_t Reg_Value;
while(I2C_GetFlagStatus(I2C1, I2C_FLAG_BUSY));

I2C_GenerateSTART(I2C1, ENABLE);
while(!I2C_CheckEvent(I2C1, I2C_EVENT_MASTER_MODE_SELECT));
I2C_Send7bitAddress(I2C1, BMP180_ADDRESS, I2C_Direction_Transmitter);
while(!I2C_CheckEvent(I2C1, I2C_EVENT_MASTER_TRANSMITTER_MODE_SELECTED));
I2C_Cmd(I2C2,ENABLE);
I2C_SendData(I2C2,RegAddress);
while(!I2C_CheckEvent(I2C1, I2C_EVENT_MASTER_BYTE_TRANSMITTED));
I2C_GenerateSTART(I2C2, ENABLE);
while(!I2C_CheckEvent(I2C1, I2C_EVENT_MASTER_MODE_SELECT));
I2C_Send7bitAddress(I2C1, BMP180_ADDRESS, I2C_Direction_Receiver);
while(!I2C_CheckEvent(I2C1, I2C_EVENT_MASTER_RECEIVER_MODE_SELECTED));
I2C_AcknowledgeConfig(I2C2,DISABLE);
while(!(I2C_CheckEvent(I2C2,I2C_EVENT_MASTER_BYTE_RECEIVED)));
Reg_Value=I2C_ReceiveData(I2C2);
I2C_AcknowledgeConfig(I2C2, ENABLE);
I2C_GenerateSTOP(I2C2,ENABLE);

}

这函数编的是对的么
