M5 CoreInk NTP Clock

[hpsaturn]

Hi everyone, I wrote a example that extend the clock to a NTP clock (using a time service to sync it) and other features, the idea is improve it and add more features.

Features

• eInk display refresh without any blink
• shutdown with RTC implementation
• run time is only 2 sec each minute
• NTP sync beep confirmation
• added implementation for ENVII hat (disabled for default)
• detecting USB charging (toggle partial update/full refresh in battery mode)
• Clock features on Left/Right wheel button
