A MagTag ESP32-S2 clock also displays weather and more #MagTag #ESP32

This project uses an Adafruit MagTag as a large font clock with date and weather. It displays in English or Russian (streaming UTF), full text word wrap for weather alerts, plays volume adjustable sinewave RTTTL ringtones, polyphonic Westminster chimes on the hour, and auto updates firmware Over The Air. There is menu selectable °F or °C, 12 or 24 hour time, Russian or English. It remembers settings, and has a WiFi console for easy connection (no SSID or Password in source), etc. And the only part is the MagTag.

The goal was easy to read, large numbers and simple layout. Succeeded on at least one of those. Icons can sometimes be confusing. I added lots of features to see what I could fit in. My philosophy is to always “stand on the shoulders of giants” instead of “re-inventing the wheel.” I use several available libraries but where I could not find one, I wrote the code. ezTime and OpenWeatherMap.org were easy choices. Writing code to properly text wrap and modifying fonts was, well, fun. I am putting most of the documentation within the code itself as to how things were done, and will but some here as well. I fully expect that if anyone gets anything out of my efforts they will be cut-and-pasting into their own design.

Graphics were done with the Adafruit_GFX library for Arduino.
