读LIS2DE12温度得出错误结果

我们在我们的设备中使用并设法获得合理的加速度数据，中断等。
但是，当我们尝试从指定的寄存器读取温度时，我们明显得出错误的结果。
这是我们尝试做的事情：
1.将0xC0写入TEMP_CFG_REG。
2.将0x80写入CTRL_REG4。
3.读取OUT_TEMP_L。
4.小延迟（**我们尝试使用和不使用它，没有看似影响**）。
5.读取OUT_TEMP_H并将其值视为温度。
有人可以指出我们是否在这个过程中做错了什么？
另外 - 我们需要以不同的方式对待结果吗？手册说“温度数据存储在OUT_TEMP_H内部，作为8位格式左对齐的两个补码数据”，但我不确定我理解这个含义。如果有人能举例说明可能有用的实际数字。
最后，手册没有指定结果的单位以及是否需要进行一些校准。
我们在假设单位是否正确
摄氏度，不需要校准？
提前致谢！

以下为原文




We're using in our device and manage to get reasonable acceleration data, interrupts etc.
However, when we try to read the temperature form the designated register, we clearly get wrong results.
Here is what we try to do:
1. write 0xC0 to TEMP_CFG_REG.
2. write 0x80 to CTRL_REG4.
3. read OUT_TEMP_L.
4. small delay (**we tried with and without it, with no seeming affect**).
5. reading OUT_TEMP_H and treating its value as the temperature.
Can someone point out if we're doing something wrong in the process?
Also - do we need to treat the outcome differently? the manual says 'Temperature data is stored inside OUT_TEMP_H as two’s complement data in 8-bit format left-justified', but i'm not sure I understand the meaning of this. If someone could give an example with actual numbers that might be helpful.
Finally, the manual doesn't specify the units of the result and whether it needs some calibration.
Are we correct in assuming the units are
Celsius and that no calibration is needed?

Thanks in advance!
