Need to create a Mopidy extension to drive the LCD1602 display. This will be based on the Pirate Audio PiDi display. The relevant folders are located under /usr/local/lib/python3.9/disp-packages
/usr/local/lib/python3.9/disp-packages
|_/mopidy-pidi
|_/pidi_display_pil
|_/pidi_display_st7789
|_/ST7789
Configuration is via the pidi section of mopidi.conf:
...
[pidi]
enabled = true
display = st7789
rotation = 90
...
mopidy-pidi
- Defines the extension for mopidy.
- Reads and verifies entries in mopidy.conf
- Creates class PiDiFrontend that adds callbacks for various Mopidy events, like playlist_changed etc.
- Implements class PiDi that contains an instance of the display defined in mopidy.config
- Callbacks from mopidy are passed to the display object.
pidi-display-pil
This is a plugin for a Tk display. Used in the st7789 to do all the layout for the overlay and artwork. Not needed for the text display.
pidi_display_st7789
This is the display plugin for the st7789. This implements the interface required by the pidi display architecture (defined in PiDi Plugin.py) and adds a few extra arguments that can be added to the config file.
ST7789
This is the Adafruit driver for the ST7789 display. Handles all the low level stuff. Imports RP.GPIO to deal with the actual hardware.
New/Replacement modules
mopidy-txtdi

Making it work
Mopidy crib sheet
==================
Location of files: /usr/local/lib/python3.9/dist-packages/...
Stop/Start/Interactive
======================
As a service:
sudo systemctl enable mopidy
sudo systemctl stop mopidy
sudo systemctl start mopidy
sudo systemctl restart mopidy
sudo systemctl status mopidy
At a terminal:
mopidy
mopidy --help
<ctrl>-C to exit.
Config file read from ~/.config/mopidy/mopidy.conf
Debug info goes to terminal
Fix to make files easy to edit:
sudo su
find /etc/weewx -exec chmod o+w {} \;
find /var/www/html -exec chmod o+w {} \;
