LPS25HB Register description

8.17 TEMP_OUT_H (2Ch)

Temperature output value (MSB)

The temperature output value is a 16-bit data that contains the measured temperature. It is

composed by TEMP_OUT_H (2Ch) and TEMP_OUT_L (2Bh). The value is expressed as

2’s complement.

8.18 FIFO_CTRL (2Eh)

FIFO control

FIFO Mean mode:

The FIFO can be used for implementing a HW moving average on the

pressure measurements. The number of samples of the moving average can be 2, 4, 8, 16

or 32 samples by selecting the FIFO Mean mode sample size as per Table 23. Different

configurations are not allowed.
