I have now made my own first module, please see https://github.com/kagjerde/MMM-Avinor for details.

I am looking for list of flights from any airport in Norway.

Avinor has an API example: https://flydata.avinor.no/XmlFeed.asp?TimeFrom=1&TimeTo=1&airport=KRS&direction=D

API info:
https://avinor.no/konsern/tjenester/flydata/flydata-i-xml-format

I am not a programmer, but uses the Avinor app quite frequently, and it would be cool if MM can display the flight status.
