Resin implementation for python metro display program. Shows custom info on old metro displays with hacked serial connection.

Metrotaulu Python on ResinOS

** requires update to balenaOS (resinOS follower) **

This is metro display control on the Rasperry Pi using Python with ResinOS

The serial device should be mounted to "/dev/ttyUSB0" Please see http://sooda.dy.fi/2013/3/29/omaa-tekstia-metronayttoihin/ and https://github.com/sooda/metro_station_display for more info on circuit design. And for me only working adapter was: http://www.aten.com/global/en/products/usb-&-thunderbolt/usb-converters/uc232a/

Some guides: https://resinos.io/docs/raspberry-pi/gettingstarted/

Some info: https://runnable.com/docker/python/dockerize-your-python-application

Image for the development machine: https://hub.docker.com/r/resin/raspberry-pi-python/

Systemd is somehow related to relaunch of the app: https://en.wikipedia.org/wiki/Systemd http://www.diegoacuna.me/how-to-run-a-script-as-a-service-in-raspberry-pi-raspbian-jessie/ But all you need is (in Dockerfile): ENV INITSYSTEM on

All you need to do is :

• clone this repo locally
• get .cache-«username» -file by running spotipy.util.prompt_for_user_token with computer using browser for the first time
• connect 'serial converted to USB on RPI0W with ResinOS' in cardslot
• add the resin to development machine
• sudo resin local push «devname».local -f --source .
  • debugging: ssh root@«devname».local -p22222
• enjoy the timely info on the display...
• my devname: metroresin
