Adafruit VCNL4040 Shield
Overview
The Adafruit VCNL4040 Proximity and Lux Sensor Shield features a Vishay VCNL4040 Proximity and Lux Sensor and two STEMMA QT connectors.
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.

In order to use interrupts you need to connect a separate wire from the
shield to a GPIO pin on your microcontroller board. See
vishay,vcnl4040 for documentation on how to adjust the
devicetree file.
Programming
Set --shield adafruit_vcnl4040 when you invoke west build. For example
when running the VCNL4040 Proximity and Ambient Light Sensor proximity and light sample:
# From the root of the zephyr repository
west build -b adafruit_qt_py_rp2040 --shield adafruit_vcnl4040 samples/sensor/vcnl4040/
