CircuitPython library for the Rohm BD3491FS Audio Processor


This driver depends on:

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install adafruit-circuitpython-bd3491fs

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

sudo pip3 install adafruit-circuitpython-bd3491fs

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .venv
source .venv/bin/activate
pip3 install adafruit-circuitpython-bd3491fs

Usage Example

import board
import adafruit_bd3491fs
import busio

i2c = busio.I2C(board.SCL, board.SDA)
bd3491fs = adafruit_bd3491fs.BD3491FS(i2c)

bd3491fs.active_input = adafruit_bd3491fs.Input.A
bd3491fs.input_gain = adafruit_bd3491fs.Level.LEVEL_20DB
bd3491fs.channel_1_attenuation = 0
bd3491fs.channel_2_attenuation = 0
