In order to bring consistency in-tree, migrate all samples to the use
the new prefix <zephyr/...>. Note that the conversion has been scripted:
```python
from pathlib import Path
import re
EXTENSIONS = ("c", "h", "cpp", "rst")
for p in Path(".").glob("samples/**/*"):
if not p.is_file() or p.suffix and p.suffix[1:] not in EXTENSIONS:
continue
content = ""
with open(p) as f:
for line in f:
m = re.match(r"^(.*)#include <(.*)>(.*)$", line)
if (m and
not m.group(2).startswith("zephyr/") and
(Path(".") / "include" / "zephyr" / m.group(2)).exists()):
content += (
m.group(1) +
"#include <zephyr/" + m.group(2) +">" +
m.group(3) + "\n"
)
else:
content += line
with open(p, "w") as f:
f.write(content)
```

.. _fade-led-sample: Fade LED ######## Overview ******** This application "fades" a LED using the :ref:`PWM API <pwm_api>`. The LED starts off increases its brightness until it is fully or nearly fully on. The brightness then decreases until the LED is off, completing on fade cycle. Each cycle takes 2.5 seconds, and the cycles repeat forever. The PWM period is taken from Devicetree. It should be fast enough to be above the flicker fusion threshold. Requirements and Wiring *********************** This sample has the same requirements and wiring considerations as the :ref:`pwm-blinky-sample`. Building and Running ******************** To build and flash this sample for the :ref:`nrf52840dk_nrf52840`: .. zephyr-app-commands:: :zephyr-app: samples/basic/fade_led :board: nrf52840dk_nrf52840 :goals: build flash :compact: Change ``nrf52840dk_nrf52840`` appropriately for other supported boards. After flashing, the sample starts fading the LED as described above. It also prints information to the board's console.
