Requirements

This shield can be used with boards which provide an I2C connector, for example STEMMA QT or Qwiic connectors. The target board must define a zephyr_i2c node label. See Shields for more details.

Pin Assignments

Shield Pin	Function
SCK	LPS22 I2C SCL
SDI	LPS22 I2C SDA
SDO	LPS22 I2C address adjust
CS	LPS22 mode. Pulled high to use I2C.
INT	LPS22 interrupt out

See st,lps22hb-press for documentation on how to adjust the devicetree file.

Programming

Set --shield adafruit_lps22 when you invoke west build. For example when running the Barometric pressure and temperature sensor polling example pressure and temperature sample:

# From the root of the zephyr repository
west build -b adafruit_feather_rp2040 --shield adafruit_lps22 samples/sensor/pressure_polling
west flash
