LIS3DH: 12 Bit Resolution and FIFO Mode

Posted on November 30, 2017 at 11:19

Given that the LIS3DH FIFO is only 10 bit wide, is it actually possible to run the accelerometer with 12 bit resolution?

I think if the sensor is configured int Low-power mode (8-bit resolution) also only 8-bit value is stored in the FIFO (the low bytes are 0).

If FIFO is disabled and the sensor is configured into High-resolution mode the output is 12-bit.

As I anticipated, thank you.

Does this mean that similarly if I have the sensor configured into a FIFO mode with 8 bit resolution I will still achieve 8 bit resolution?
