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)
```

.. _ht16k33: HT16K33 LED driver with keyscan ############################### Overview ******** This sample controls the LEDs connected to a `Holtek HT16K33`_ driver. The sample supports up to 128 LEDs connected to the rows/columns of the HT16K33. The LEDs are controlled using the following pattern: 1. turn on all connected (up to 128) LEDs one-by-one 2. blink the LEDs at 2 Hz, 1 Hz, and 0.5 Hz 3. reduce the brightness gradually from 100% to 0% 4. turn off all LEDs, restore 100% brightness, and start over The sample logs keyscan events on the console. Building and Running ******************** Build the application for the :ref:`nrf52840dk_nrf52840` board, and connect a HT16K33 LED driver at address 0x70 on the I2C-0 bus. .. zephyr-app-commands:: :zephyr-app: samples/drivers/ht16k33 :board: nrf52840dk_nrf52840 :goals: build :compact: For flashing the application, refer to the Flashing section of the :ref:`nrf52840dk_nrf52840` board documentation.
