I do not set the low power mode of the LIS3DH sensor properly.

I am using the ST LIS3DH sensor, and would like to try the low power operation mode, but the results I see on the display are not what I expected, since at rest, instead of seeing values of + -1g, I see values of + -3g, with a full scale of 2g.And I ...

Resolved! Hello, I'm currently testing the IIS3DWB accelerometer. The Datasheet says that the Timestamp tick resolution ist 25 us. All my measurements show, that the real resolution is 12.5 us. Is this correct?

This actually makes sense because the ODR is 26,667 kHz which means that between two samples are 37.5 us this would make three 12.5 us ticks. 25 us wouldn't make much sense.

Question regarding implementation of LIS3DSH Standard C library.

Hi,I was taking a look at the STMems Standard C Library for the LIS3DSH. The implementation of the function lis3dsh_status_get looks a bit weird as there are 2 calls to the lis3dsh_write_reg functions.int32_t lis3dsh_status_get(stmdev_ctx_t *ctx, lis...

Resolved! Using INT2 on LIS3DSH for DRDY signal

Hi,I'm using a STM32F4 board which has a LIS3DSH. This board has PE0 connected to the INT1 of the LIS3DSH and PA0 connected to the user Button B1. Due to this, I won't be able to use interrupts to sample and interrupt for button press. I'm trying to...
