硬复位时软件不匹配

你好Miroslav，我已经完成了IIS2DH加速器的以下配置。
///////////////////////////示例代码///////////////////// ///////////////////////////////
响应= LIS3DH_GetWHO_AM_I（安培; who_am_i）;

如果（who_am_i == IC_READ_SUCCESS）{
print（'Who AM I％x  r  n'，who_am_i）; unsigned char响应，状态;

AxesRaw_t数据;
response = LIS3DH_SetODR（LIS3DH_ODR_10Hz）;
如果（响应== 1）{
打印（ 'SET_ODR_OK  r  n'）;
}
response = LIS3DH_SetMode（LIS3DH_LOW_POWER）;
如果（响应== 1）{
打印（ 'SET_MODE_OK  r  n'）;
}
response = LIS3DH_SetFullScale（LIS3DH_FULLSCALE_2）;
如果（响应== 1）{
打印（ 'SET_FULLSCALE_OK  r  n'）;
}
response = LIS3DH_SetAxis（LIS3DH_X_ENABLE | LIS3DH_Y_ENABLE | LIS3DH_Z_ENABLE）;
如果（响应== 1）{
打印（ 'SET_AXIS_OK  r  n'）;
}
response = LIS3DH_SetFilterDataSel（MEMS_ENABLE）;
如果（响应== 1）{
print（'过滤数据选择启用 r  n'）;
}而（1）

{
response = LIS3DH_GetAccAxesRaw（＆amp; data）;
如果（响应== 1）{
data.AXIS_X = data.AXIS_X＆gt;＆gt; 8;
data.AXIS_Y = data.AXIS_Y＆gt;＆gt; 8;
data.AXIS_Z = data.AXIS_Z＆gt;＆gt; 8;
print（'x％d y％d z％d  r  n'，data.AXIS_X，data.AXIS_Y，data.AXIS_Z）;
}
}}

其他{
print（'设备读取失败 r  n'）;
} ///////////////////////////////////// ***** /////// ////////////////////////////////////////////
当我通过软复位重启thr board时，它给出了以下X，Y和Z原始数据：

x -1 y -1 z 0
x 0 y -2 z 1
x -1 y 0 z -2
x 0 y -1 z 1
x -1 y 0 z 0
x 1 y -1 z 0
x 0 y 0 z 0
x 0 y -1 z 0
x -1 y -1 z -1
x -1 y -1 z 0
x 0 y 0 z -1
x 0 y -1 z -1
x 1 y 0 z 0
x 0 y 0 z -2
x 0 y 1 z -2
x 0 y 0 z 0
x -1 y -1 z -2
x -1 y -1 z -1
x 0 y -1 z 0
硬盘重启时，跟随原始数据：
x -2 y 62 z -12
x -1 y 55 z -11
x -1 y 47 z -9
x -1 y 42 z -10
x -1 y 37 z -7
x -2 y 31 z -6
x -1 y 27 z -7
x -1 y 24 z -7
x 0 y 20 z -5
x -1 y 18 z -4
x -1 y 15 z -4
x -1 y 12 z -1
x -1 y 10 z -2
x 0 y 10 z -3
x -2 y 8 z -2
x -1 y 7 z -2
x -1 y 6 z -1
x -2 y 5 z -2
x -1 y 4 z -1
x 0 y 4 z -1
x 0 y 3 z -1
x 0 y 2 z -2
x -1 y 3 z -3
x 0 y 1 z -1
x -1 y 2 z -1
x 0 y 1 z -2
x -1 y 1 z -2
x 0 y 1 z 0
x 0 y 1 z -1
x -2 y 0 z 0
x 0 y 0 z 0
因此，在硬重启读数中，您已经看到前15-20个读数有些不可用，之后它的稳定读数几乎为零。为什么会这样？你能解决一下吗？

When I reboot thr board by soft reset it has given following X,Y and Z raw data:

x -1 y -1 z 0
x 0 y -2 z 1
x -1 y 0 z -2
x 0 y -1 z 1
x -1 y 0 z 0
x 1 y -1 z 0
x 0 y 0 z 0
x 0 y -1 z 0
x -1 y -1 z -1
x -1 y -1 z 0
x 0 y 0 z -1
x 0 y -1 z -1
x 1 y 0 z 0
x 0 y 0 z -2
x 0 y 1 z -2
x 0 y 0 z 0
x -1 y -1 z -2
x -1 y -1 z -1
x 0 y -1 z 0
And following raw data when Hard reboot the board:
x -2 y 62 z -12
x -1 y 55 z -11
x -1 y 47 z -9
x -1 y 42 z -10
x -1 y 37 z -7
x -2 y 31 z -6
x -1 y 27 z -7
x -1 y 24 z -7
x 0 y 20 z -5
x -1 y 18 z -4
x -1 y 15 z -4
x -1 y 12 z -1
x -1 y 10 z -2
x 0 y 10 z -3
x -2 y 8 z -2
x -1 y 7 z -2
x -1 y 6 z -1
x -2 y 5 z -2
x -1 y 4 z -1
x 0 y 4 z -1
x 0 y 3 z -1
x 0 y 2 z -2
x -1 y 3 z -3
x 0 y 1 z -1
x -1 y 2 z -1
x 0 y 1 z -2
x -1 y 1 z -2
x 0 y 1 z 0
x 0 y 1 z -1
x -2 y 0 z 0
x 0 y 0 z 0
So, in that hard reboot readings you have seen that first 15-20 readings are some unusaul and after that it has stable readings nearly to zero. Why this is happened? Can you please give some solution on that.
