This is a great battery-backed real time clock (RTC) that allows your
microcontroller project to keep track of time even if it is reprogrammed,
or if the power is lost. Perfect for datalogging, clock-building,
time stamping, timers and alarms, etc. The DS1307 is the most popular
RTC - but it requires 5V power to work.
The DS1307 is simple and inexpensive but not a high precision device. It may
lose or gain up to two seconds a day. For a high-precision, temperature
compensated alternative, please check out the
`DS3231 precision RTC <https://www.adafruit.com/products/3013/>`_.
If you do not need a DS1307, or you need a 3.3V-power/logic capable RTC
please check out our affordable
`PCF8523 RTC breakout <https://www.adafruit.com/products/3295>`_.

Dependencies
=============
This driver depends on:
* `Adafruit CircuitPython <https://github.com/adafruit/circuitpython>`_
* `Bus Device <https://github.com/adafruit/Adafruit_CircuitPython_BusDevice>`_
* `Register <https://github.com/adafruit/Adafruit_CircuitPython_Register>`_
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-ds1307/>`_. To install for current user:
.. code-block:: shell
pip3 install adafruit-circuitpython-ds1307
To install system-wide (this may be required in some cases):
.. code-block:: shell
sudo pip3 install adafruit-circuitpython-ds1307
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-ds1307
Usage Notes
===========
Of course, you must import the library to use it:
.. code:: python3
import board
import adafruit_ds1307
import time
All the Adafruit RTC libraries take an instantiated and active I2C object
(from the ``board`` library) as an argument to their constructor. The way to
create an I2C object depends on the board you are using. For boards with labeled
SCL and SDA pins, you can:
.. code:: python
import board
Now, to initialize the I2C bus:
.. code:: python
i2c = board.I2C()
Once you have created the I2C interface object, you can use it to instantiate
the RTC object:
.. code:: python
rtc = adafruit_ds1307.DS1307(i2c)
To set the time, you need to set ``datetime`` to a `time.struct_time` object:
.. code:: python
rtc.datetime = time.struct_time((2017,1,9,15,6,0,0,9,-1))
After the RTC is set, you retrieve the time by reading the ``datetime``
attribute and access the standard attributes of a struct_time such as ``tm_year``,
``tm_hour`` and ``tm_min``.
.. code:: python
t = rtc.datetime
print(t)
print(t.tm_hour, t.tm_min)
