FXOS8700CQ - Time-aligned accelerometer/magnetometer measurements

Question asked by Jeffrey Monaco on Sep 6, 2014

Hi all,

 

I am using the FXOS8700CQ six axis sensor, and can read the (x,y,z) accelerometer measurements and (x,y,z) magnetometer measurements without issue from their dedicated registers.

 

The data sheet also references complementary/companion registers that hold accelerometer readings that are time-aligned with the magnetometer values. However, if I query these registers (at 0x39 et seq), the values are always zero.

 

Any pointers on procedures or special setup steps that need to be taken to get meaningful values from these registers?

 

Thanks
