Hello
I am using BMA253 and I am accually able to read the orientation interrupt status on BMA253.
Can you help me understand what the φ(phi) is in the 4.7.7 Orientation recognition, Figure 9, of the BMA253 data sheet (bst-bma253-ds000.pdf).
Image of the Figure 9 is also attached.(image.png)
Is there documents on BMA253 orientation to get a better understanding of it or should I just stick with the BMA253 data sheet.
And from the orient<2:0> in 0x0C(INT_STATUS_3) can you distinguish six different sensor orientations shown in Table 25 in page 110 of BMA253 datasheet, 9.2 Sensing axes orientation?
Image of the Table 25 is also attached.(image2.png)

I found this post, and I think I can find my answer in FAE_CA1's reply in that post.
He showed us the below pdf file.

Thanks anyways
