Hi

Has nobody used the sensor using SPI interface? I have a power up issue, if CS is left floating till processor drive it to zero it seems device start as i2C and micro Dout is shorted to ground.

    If you control the LPS22HB via SPI, you should fix CS to GND in your special case via a pull-down of e.g. 10k, so that CS cannot float.
