Network Time Protocol (NTP) helper for CircuitPython.

Dependencies

This driver depends on:

• Adafruit CircuitPython <https://github.com/adafruit/circuitpython>_

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle <https://github.com/adafruit/Adafruit_CircuitPython_Bundle>_.

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI <https://pypi.org/project/adafruit-circuitpython-ntp/>_. To install for current user:

.. code-block:: shell

pip3 install adafruit-circuitpython-ntp

To install system-wide (this may be required in some cases):

.. code-block:: shell

sudo pip3 install adafruit-circuitpython-ntp

To install in a virtual environment in your current project:

.. code-block:: shell

mkdir project-name && cd project-name
python3 -m venv .venv
source .venv/bin/activate
pip3 install adafruit-circuitpython-ntp

Usage Example

.. code-block:: python

import adafruit_connection_manager
import adafruit_ntp
import os
import time
import wifi

wifi_ssid = os.getenv("CIRCUITPY_WIFI_SSID")
wifi_password = os.getenv("CIRCUITPY_WIFI_PASSWORD")
wifi.radio.connect(wifi_ssid, wifi_password)

pool = adafruit_connection_manager.get_radio_socketpool(wifi.radio)
ntp = adafruit_ntp.NTP(pool, tz_offset=0, cache_seconds=3600)

while True:
    print(ntp.datetime)
    time.sleep(1)
