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
SDA	ISM330DHCX I2C SDA
SCL	ISM330DHCX I2C SCL
DO	ISM330DHCX I2C address selection. Pull down by default.
CS	ISM330DHCX Force I2C mode by setting it to high level.
I1	ISM330DHCX Interrupt out
I2	ISM330DHCX Second interrupt out

In order to use interrupts you need to connect a separate wire from the shield to a GPIO pin on your microcontroller board. See st,ism330dhcx for documentation on how to adjust the devicetree file.

Programming

Set --shield adafruit_ism330dhcx when you invoke west build. For example when running the Generic 3-Axis accelerometer polling sample:

# From the root of the zephyr repository
west build -b adafruit_qt_py_rp2040 --shield adafruit_ism330dhcx samples/sensor/accel_polling
