Executive Summary
Our project involves interfacing with six LED matrices and audio input. The goal is to take the audio input, perform a frequency domain analysis, and then display the frequency spectrum onto the LED matrices as a spectrometer.

Installation Instructions
GitHub
The project is located on GitHub here: https://github.com/grinstba/LEDMatrix
Hardware
Here are the links for the specific hardware we used for this project.
We borrowed a six panel LED Matrix, power supply, pocket beagle, and pocket scroller cape from Dr. Yoder.

Installation
Go to https://falcon-player.gitbooks.io/falcon-player-manual/content/chapter_three_installation/downloading_the_falcon_player.html and follow the instruction to download the latest falcon player image and then flash it to one of your SD cards. Make sure to download the Beagle Bone image and not the Raspberry Pi image. Also, we were not running the falcon player off of eMMC.
Once falcon player is installed, boot up your Beagle Bone and ssh into it with the following credentials:
- username: fpp
- password: falcon
Once connected to the Beagle Bone, go ahead and clone our GitHub project from https://github.com/grinstba/LEDMatrix.
Once the projected has cloned, run the install.sh script to install the needed packages for the project to run.
User Instructions
Many of the following images and directions come from Mark A. Yoder's documentation found here
In order to light up an entire 32x64 LED panel white (Red, Green, and Blue all on), you will need at least a 5V 4A power supply. Each panel has a single power connection and a data in and data out connection. The data in connections control how the panel operates and the data out connections allow you to daisy chain the panels together to created a large display. The image below shows the connection.
Highlights
Here is where you brag about what your project can do.
Include a YouTube demo the audio description.
Theory of Operation
Give a high level overview of the structure of your software. Are you using GStreamer? Show a diagram of the pipeline. Are you running multiple tasks? Show what they do and how they interact.
Work Breakdown
Date | Milestone | Notes |
---|---|---|
10/26/2019 | Controll LED matrix with Falcon Player | Brock primarily downloaded and installed Falcon Player to the pocket beagle. Blake primarily setup the LED matrix with the power supply and configured Falcon Player to control the LEDs. |
10/29/2019 | Gain root access to the Falcon Player | Brock primarily gained root access to the pocket beagle and allowed the pocket beagle to connect to the internet through a host computer |
11/4/2019 | Control the LED matrix via a script running on the pocket beagle | Blake and Brock worked together to figure out how to control the LED matrix with a python script |
11/12/2019 | Have the audio spectrometer fully working | |
11/16/2019 | Add some flashy features to the spectrometer display | |
11/18/2019 | Final documentation |
