So I use accelerometer to get acceleration data. However, I have trouble understanding data. I have been reading manual, but it does not help me:
The measured acceleration data are sent to the OUTL_X, OUTH_X .....
The complete acceleration data for the X channel is given by the concatenation OUTL_X & OUTH_X
and is expressed as a 2’s complement number.
Acceleration data are represented as 12-bit numbers (left justified).
I understand the concept of 2s complement and left justified number spread in this case, however, I am unable to understand how to arrive at appropriate acceleration values.
The table with couple examples is also provided:
acc value OUTL_X OUTH_X
0 g 0x00 0x00
343 mg 0xE0 0x15
1004 mg 0x00 0x40
-343 mg 0x20 0xEA
-1004 mg 0x00 0xC0
It would be really helpful if someone helped to figure out how do manufacturers of accelerometer arrive at these values. This is little endian.
