LSM303DLHC加速度计数据寄存器左对齐吗？

你好

我按如下方式配置了LSM303DLHC加速度计。
CTRL_REG1_A，带有0x77 // 400hz数据
CTRL_REG4_A与0x00 //小端
并开始从OUT___A寄存器读取数据。

但我可以找到一些东西，发现下部的半字节一直都是零
OUT___A，OUT___A，OUT___A寄存器。

那么LSM303 12bit中的数据左对齐还是我遗漏了什么？

注意：在数据表中我发现它是16位，但在某些驱动程序样本中，数据寄存器的值被组合并右移4位（我假设这是为了补偿左对齐数据）

问候

Hi

I configured the LSM303DLHC accelerometer as follows.
CTRL_REG1_A with 0x77  //400hz data
CTRL_REG4_A with 0x00 //Little endian
And started reading the data from the OUT___A registers.

But I could find something that the lower nibble was found to be zero all the time in the
OUT___A, OUT___A, OUT___A registers.

So is the data in LSM303 12bit left justified or am I missing something?

Note: In datasheet i found it is 16bit but in some driver samples the values of the data registers are combined and right shifted by 4 bits (I assume this is to compensate the left justified data)
