I want to chain in SPI several LPS22HB pressure sensors. I would like to realize a daisy chain or a serial SPI chain.

A daisy chain seems to be complicated because i can not configure the SPI chain in 4 wired at power up.Or, I would like to connect a specific CS on each LPS22HB and connect SCL / SDI / SDO together on the same SPI bus of the MCU. But I do not underst...

Resolved! Pressure of sensor LPS22HB always equal to 0.0

I use a STEVAL-IDB008V2 and connect sensor LPS22HB to it. By I2C bus , my program communicate with the sensor and it receve interrupt for end of pressure acquisition. The problem is that the pressure read is always equal to 0.0.

Do these IIS2DLPC XYZ output values look correct?

Hello, I apologize in advance for my long post, and ignorance when it comes to interpreting this linear accelerometer data. The only one I have used in the past gave me euler angles, and I had no problem calculating tilt from them. I am trying to per...
