The Neopixel is connected to pin P16, not P12. In order to make it work I had to change to PIO0, like the other Adafruit Feather boards with Neopixel. The original devicetree entry seems to be from boards/adafruit/qt_py_rp2040/adafruit_qt_py_rp2040.dts That board powers the Neopixel from a GPIO pin, why that GPIO line had to be hogged. This board powers the Neopixel from +3.3 Volt, why no GPIO hogging is necessary. See https://learn.adafruit.com/adafruit-feather-rp2040-pico/downloads for schematic. Tested with west build -b adafruit_feather_rp2040 samples/drivers/led/led_strip/ Signed-off-by: Jonas Berg <[email protected]>
