Epaper Digital watch using an ESP32 Tinypico

This is a "deepsleep" esp32 digital wristwatch.
If you need to adjust the strap size just send me a message. I build this with the rests of a Peeble dead watch.

If it's built using a [tinypico.com esp32](https://tinypico.com) then it should last up to 3 days with a 80 mA battery. Provided it connects only once per day to sync time with WiFi.

Please note that the Firmware is based on ESP-IDF and won't work with Arduino framework. For more information and previews check the following page:

Two options for the epapers, both 200x200 pixels resolution:
Waveshare 1.54
Heltec 1.54

Mind setting the right class when you compile it using ESP-IDF and also doing a:

idf.py menuconfig

And adjust display configuration to match the connected ESP3
