LSM303AGR能否用于测量环境温度？

你好，
我正在使用LSM303AGR，加速度计和磁力计，没有任何问题，但现在我想用嵌入式温度传感器进行一些测试，数据表并没有说太多。
首先，请您确认TEMP_CFG_REG_A寄存器的用法吗？

如数据表所示，向其写入0xC0似乎无法启用温度测量，但写入0x80似乎也有效。那么请您澄清数据的解释吗？该值作为二进制补码存储在OUT_TEMP_H中，但是有一个偏移量要考虑吗？
最后，这个嵌入式传感器能否成功用于测量环境温度？我们需要校准每台设备以获得准确的结果吗？

谢谢你的帮助，纪尧姆

Hello,
I'm using the LSM303AGR, accelerometer and magnetomter, without any problems but now I would like to do some tests with the embedded temperature sensor and datasheet doesn't says much about it.
Firstly could you please confirm the usage of the register TEMP_CFG_REG_A ?

Writing 0xC0 to it, as specified by the datasheet doesn't seem to enable temperature measurements, however writing 0x80 seems to work.Then could you please clarify the interpretation of the data ? The value is stored in OUT_TEMP_H as two's complement but is there an offset to account for ?
Finally, could this embedded sensor be successfully used to measure ambiant temperature ? Would we need to calibrate each device to obtain an accurate result ?


Thanks for your help,Guillaume
