Hardware Setup
Setup instructions for the hardware are covered in onlaj/Piano-LED-Visualizer.
It lists out all of the parts and equipment, and references a lot of other sites with useful information on how
to setup and configure the hardware. Here are some of my takeaways:
LED
For a standard 88-key piano, the distance from lowest and highest key is just 4 meters. The WS2818B LEDs
have enough LED density to align with every key, so 4 meters of that will be around 172 LEDs.
It is recommended to purchase the longer-lengthed strip and cut it down to 4 meters. Soldering two
shorter strips together is more tedious. Here is a good instructional video
on how to do that.
Finding vendors selling 4 meter long aluminum casing was also troublesome. Here is a vendor
that offers custom-length cases and lids.
Get a 5V power supply that draws 10A of current.
Raspberry Pi
The instructions for setting up the Raspberry Pi are pretty straight forward, but here are some issues that I ran into:
Installing Rasbian
To enable wifi: do not need to set country code value in wap_supplicant.conf if you have Raspbery Pi Zero
Configuring Raspbian to work with WS2128
To disable sound: if /etc/modprobe.d/alsa-base.conf is not found, try /usr/share/alsa/alsa.conf
Enabling SPI
Configuring MIDI
Missing Jack module errors: sudo apt-get install libjack-dev
Python 3 packages: libatlas-base-dev
Additional packages that might be needed
sudo apt-get install libjpeg-dev zlib1g-dev
Install/Run
Setup your virtual environment
virtualenv <path to env>
source <path to env>/bin/activate
Install project from package or source
To install from pypi:
# in raspberry pi, install the project from pypi
pip3 install pyanoled
To install from source:
# in raspberry pi, clone repository
git clone <repository>
# in project root directory, run setuptools
# note: some dependencies (like numpy) can take a long time to install this way. can install those
# dependencies through pip first before running this step
python3 setup.py develop
Run project
# console script setup as entrypoint
