Programming
LED Strip Example
Set --shield adafruit_neopixel_grid_bff when you invoke west build. For example:
# From the root of the zephyr repository
west build -b adafruit_qt_py_rp2040 --shield adafruit_neopixel_grid_bff samples/drivers/led/led_strip
LED Display Matrix Example
Warning
When using this example, all of the LEDs will be set to their maximum brightness. Having all of the LEDs on at once can cause the PCB to overheat or draw too much current from any on-board voltage regulators. Adafruit does provide solder pads for your own power supply on the underside of the BFF for this reason. It is not required, but is strongly recommended if all of the LEDs are fully on for any significant amount of time.
Set --shield adafruit_neopixel_grid_bff_display when you invoke west build. For example:
# From the root of the zephyr repository
west build -b adafruit_qt_py_rp2040 --shield adafruit_neopixel_grid_bff_display samples/drivers/display
