<![CDATA[M5 CoreInk NTP Clock]]>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

Thanks for this, it was very usefull to me for handling my brand new M5 CoreInk :)

It should definitely be in the Github examples from M5.
