Schedule Format

The Rasberry Pi Pico will retrieve your schedule from a web server, the screen can display up to 7 subjects, if more are defined "..." will be displayed instead, if the day dosen't contain any subject a "free" screen will be displayed. Example Schedule:

{
  ...
  "weekly_schedule": {
    "0": [
      {
        "time": "08",
        "subject": "Hello World!"
      }
    ],
    "1": [
      ...
    ],
    "2": [
      ...
    ],
    "3": [
      ...
    ],
    "4": [
