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	TSL2591 I2C SDA
SCL	TSL2591 I2C SCL
INT	TSL2591 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 ams,tsl2591 for documentation on how to adjust the devicetree file.

Programming

Set --shield adafruit_tsl2591 when you invoke west build. For example when running the Generic Light Sensor Polling light measurement sample:

# From the root of the zephyr repository
west build -b adafruit_qt_py_rp2040 --shield adafruit_tsl2591 samples/sensor/light_polling
