# OpenPuck — Zephyr RTOS port.
#
# Migrated from the Arduino/Adafruit-nRF52/TinyUSB sketch in ../OpenPuck.
# Build (from a west workspace with this repo reachable):
#   west build -b adafruit_feather_nrf52840 OpenPuckZephyr
#
# The bare-metal RADIO peripheral is driven directly (no BLE/802.15.4), so the
# Bluetooth/IEEE802154/MPSL stacks are disabled in prj.conf and the RADIO IRQ is
# owned by this app.
