This is supposed to be a python script powering an audio book player using the Rasperry Pi, three push buttons, two rotary encoders (with push buttons) and a 128x64 pixel OLED display.
Requires python3 and the libvlc bindings for it, namely python-vlc.
Also requires the Adafruit_SSD1306 python library.
And some other stuff I forgot about.
Using the audio jack with some speakers or headphones might yield a very low volume by default. Setting ALSA's volume to 100% helps:
amixer set PCM -- 100%
Also, the Rasperry will, by default, send audio through HDMI if there is a device connected there. However, during development, it can be helpful to force the audio through the audio jack, for example when the Pi is hooked up to a TV for coding purposes, but sound is supposed to come out of speakers connected to the audio jack. For that, these amixer commands can be used:
amixer cset numid=3 0
amixer cset numid=3 1
amixer cset numid=3 2
Where 0 is auto, 1 is jack and 2 is hdmi.
Don't use rc.local to auto-start whispery, it will lead to issues. Instead, you can use crontab with the regular user (pi):
crontab -e
@reboot /home/pi/workspace/whispery/whispery.py &
