Motion / acceleration sensor (wake-up?)

SARA AFF
#1

I believe the sara device is equiped with a motion and acceleration sensor. Is there any documentation on how to read any of the information?

And is it possible to let the device sleep for a longer time and let it wake-up on motion?

Hi,

We made an example for the LSM303AGR on the ONE suport page.

Hi Jan,

The example give’s nice readings of the XYZ. When I flip the board the Z becomes negative (below the threshold) but no interupt is triggering the “board flipped” message :confused:.

Does the SARA board need other initialization?

Kind regards,
Arno

Dear Arno,

Sorry for the late reply.

You need to change this pin:
#define ACC_INT_PIN 4 SODAQ ONE
to
#define ACC_INT_PIN ACCEL_INT1 SODAQ SARA AFF (D19)
