asm330lhh. XYZ values do not correspond to the actual location

[SPere.4]

Hi,

I using test library from ST:

https://github.com/STMicroelectronics/STMems_Standard_C_drivers/blob/master/asm330lhh_STdC/examples/asm330lhh_read_data_pollng.c

My code is based to this code.

and I can`t fugure out why Y is too small (and not shows negative values) and Z is always 0

I placed it in all projections, according to the picture:

a) Acceleration [mg]:-32.82    3.84      0.00
b) Acceleration [mg]:-997.47   15.49     0.00
c) Acceleration [mg]:1004.24   15.37     0.00
d) Acceleration [mg]:24.34     11.59     0.00 
e) Acceleration [mg]:17.08     0.06      0.00
f) Acceleration [mg]:9.64      0.00      0.00

Hi @Akellaerepelkin​ ,

I'm not sure you are reading the Y and Z axis well as the X axis... Are you using the I2C or SPI interface? And are you configure a single or a multiple reading pattern? In this second case, I would suggest you to check the correct pattern, from datasheet p.25 and 27.

By the way, can you correctly read all the other registers?
