Sorry in advance if this readme is too vague, i made this project months ago and forgot all the initial setup i had to do.
if you wanna make this repo better please submit a pr and ill gladly let people collaborate!
This repo is based off the https://github.com/hzeller/rpi-rgb-led-matrix project, so youll have to already have the matrix and raspberry pi setup per their instructions, the rest is pretty easy to get going.
clone this repo into your pi
clone the submodule
git submodule init
git submodule update
make the matrix submodule
cd ./matrix
make
install some needed libraries for this project to compile
sudo apt-get install libasound2-dev
sudo apt-get install libncurses-dev
grant access to the interface youre using
sudo adduser <username> audio
then make the osc project
cd ..
make
finally were ready to run the ohsillyscope
the code uses alsa/pulseaudio to interpret an audio signal, so you have to pass which audio card it is reading from.
to find your audio interface, run
aplay -l
then use the card number that corresponds to the audio you want to capture. In my case my interface shows up as card 1 so the startup command is:
./osc "hw:1"
have fun :)
