Raspberry Pi Music Player

Music Player running on Raspberry Pi with buttons for play, pause, nex/prev track, shuffle and repeat. Potentiometer for volume control and toggle switch for mute / dim. Powered by Volumio.

My addition is code to read the buttons and switches and control the standard volumio interface.

See the full video on the Element14 Comunnity

Installation

• Follow the normal install instructions for Volumio
• Enable SSH
• Configure the Official Raspberry Pi Display

Note on configuring the display: Do not change the volumio password before you install. Volumio requires that the password be volumio to install. It is hardcoreded in their install scripts.

Python & Python Modules

This turned out to be a pain, needs python version > 3.5 which introduced a bunch of issues installing. Its doable, but not straight forward or easy. I used pyenv to get the right version, then satisfied dependencies as they came up with module installation. Once you have ver > 3.5 installed then proceed.

Easiest way to do this is with pyenv. Check here for details.

Also compile openssl from source and set flags like this:

export LDFLAGS="-L/usr/local/lib/"
export LD_LIBRARY_PATH="/usr/local/lib/"
export CPPFLAGS="-I/usr/local/include -I/usr/local/include/openssl"
