CircuitPython driver for the TLV320DAC3100 I2S DAC
|
|
|
|
|
|
Dependencies
|
|
=============
|
|
This driver depends on:
|
|
|
|
* `Adafruit CircuitPython <https://github.com/adafruit/circuitpython>`_
|
|
* `Bus Device <https://github.com/adafruit/Adafruit_CircuitPython_BusDevice>`_
|
|
|
|
Please ensure all dependencies are available on the CircuitPython filesystem.
|
|
This is easily achieved by downloading
|
|
`the Adafruit library and driver bundle <https://circuitpython.org/libraries>`_
|
|
or individual libraries can be installed using
|
|
`circup <https://github.com/adafruit/circup>`_.
|
|
|
|
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-tlv320/>`_.
|
|
To install for current user:
|
|
|
|
.. code-block:: shell
|
|
|
|
pip3 install adafruit-circuitpython-tlv320
|
|
|
|
To install system-wide (this may be required in some cases):
|
|
|
|
.. code-block:: shell
|
|
|
|
sudo pip3 install adafruit-circuitpython-tlv320
|
|
|
|
To install in a virtual environment in your current project:
|
|
|
|
.. code-block:: shell
|
|
|
|
mkdir project-name && cd project-name
|
|
python3 -m venv .venv
|
|
source .env/bin/activate
|
|
pip3 install adafruit-circuitpython-tlv320
|
|
|
|
Installing to a Connected CircuitPython Device with Circup
|
|
==========================================================
|
|
|
|
Make sure that you have ``circup`` installed in your Python environment.
|
|
Install it with the following command if necessary:
|
|
|
|
.. code-block:: shell
|
|
|
|
pip3 install circup
|
|
|
|
With ``circup`` installed and your CircuitPython device connected use the
|
|
following command to install:
|
|
|
|
.. code-block:: shell
|
|
|
|
circup install adafruit_tlv320
|
|
|
|
Or the following command to update an existing version:
|
|
|
|
.. code-block:: shell
|
|
|
|
circup update
|
|
|
|
Usage Example
|
|
=============
|
|
|
|
.. code-block:: python
|
|
|
|
import audiobusio
|
|
import audiocore
|
|
import board
|
|
|
|
import adafruit_tlv320
|
|
|
|
i2c = board.I2C()
|
|
dac = adafruit_tlv320.TLV320DAC3100(i2c)
|
|
|
|
# set mclk, sample rate & bit depth
|
|
dac.configure_clocks(mclk_freq=12000000, sample_rate=44100, bit_depth=16)
|
|
|
|
# use headphones
|
|
# helper function for default settings
|
|
dac.headphone_output = True
|
|
dac.headphone_volume = -20 # dB
|
|
# or use speaker
|
|
# helper function for default settings
|
|
# dac.speaker_output = True
|
|
# dac.speaker_volume = -15 # dB
|
|
|
|
audio = audiobusio.I2SOut(board.I2S_BCLK, board.I2S_WS, board.I2S_DIN)
|
|
|
