关于LIS3DH FIFO的问题

你好


我试图在FIFO模式下使用LIS3DH并启用滤波器。
在此模式下，X轴和Y轴值得到一些正常值（它们在-10和+10之间振荡）但Z轴值似乎绕过滤波器模式，Z轴给出例如-616如果我禁用FIFO和过滤器，则不是Z轴的值。

这是LIS3DH的某种限制吗？或者我在初始化时做错了什么。

在我的初始化代码中，寄存器使用以下值初始化：
CTRL_REG1 = 0x17
CTRL_REG2 = 0x88
CTRL_REG3 = 0x00
CTRL_REG4 = 0x40
CTRL_REG5 = 0x40
CTRL_REG6 = 0x00
FIFO_CTRL_REG = 0x40

谢谢

Hello


I am trying to use the LIS3DH in FIFO Mode with Filter enabled.
In this mode, the X-Axis, and Y-Axis values get some normal values (they oscillate between -10 and +10) but the Z-Axis value seems to have a bypass to the filter mode, the Z-Axis gives for example -616 witch is not the value for Z-Axis if i disable FIFO and Filter.

Is this some kind of limitation of LIS3DH? or am i making something wrong at initialization.

In my initialization code the registers are initialized with the following values:
CTRL_REG1 = 0x17
CTRL_REG2 = 0x88
CTRL_REG3 = 0x00
CTRL_REG4 = 0x40
CTRL_REG5 = 0x40
CTRL_REG6 = 0x00
FIFO_CTRL_REG = 0x40

Thank You
