你好,
我在高分辨率模式下将数据速率(ODR)设置为400Hz,并启用LIS2SH12的FIFO流模式。
对于3分钟的测量测试,我除了接收每个轴的72000(400 * 60 * 3)数据,但是我只收到大约68220个数据,其数据速率约为379Hz(约5%容差)。
我还测试了另外两个LIS2DH12样品,一个是378Hz,另一个是399Hz。
因此,我认为数据速率具有容忍度。
我的问题是:
1由于数据表仅提供
“典型”值,任何应用笔记都描述了数据速率的容差?
2是否可以通过寄存器设置校准数据速率?
非常感谢你。

Hello,
I set the data rate (ODR) to 400Hz in high resolu
tion mode with fifo stream mode enable of LIS2SH12.
For 3 minutes measurement test, I excepted to receive 72000 (400 * 60 * 3) data for each axis, however I only received around 68220 number of data, which the data rate is around 379Hz (~5% tolerance).
I also tested with two other LIS2DH12 samples, one is 378Hz, and the other one is 399Hz.
Therefore I suppose the data rate has tolerance with it.
Myy question are:
1 Since the data sheet only provide the
'typical' value, any application note describe the tolerance of data rate?
2 Is it possible to calibrate the data rate with register setting?
Thank you very much.
