soma_fm_pi_radio's Introduction

Soma FM Radio

Soma FM is an internet radio station with an eclectic choice of stations.
This project turns your Raspberry Pi into a dedicated Soma FM radio.
The project requires an LCD Display with RGB Backlight and Touch Buttons.

Demo:

see the file: soma_fm_pi_radio_demo.mp4

Preparation:

Obtain a Raspberry Pi 3B+ and slap on Raspbian. I used Buster.
Install the GFX Hat library:

curl -sS https://get.pimoroni.com/gfxhat | bash

There's a chance the GFX Hat library is out of date. If you get an error running the gfx hat examples, e.g. contrast-scanner.py:

File “contrast-scanner.py”, line 60, in
lcd.contrast(0)
AttributeError: ‘module’ object has no attribute ‘contrast’

This is a (hacky) fix (for python3), which grabs the latest files and uses them instead of what was installed:

cd /usr/local/lib/python3.7/dist-packages
sudo mkdir old
sudo mv gfxhat old
sudo git clone https://github.com/pimoroni/gfx-hat
sudo cp -r gfx-hat/library/gfxhat gfxhat

Pimoroni have been alerted, the thread is here: https://forums.pimoroni.com/t/gfx-hat-contrast-problems/11610

Install the VLC libary

sudo pip3 install python-vlc

run main.py to start using it. Mappings of commands to buttons are therein.
There are commands to play channels, play/pause them and shutdown the pi in this file too.
