EPClock

ESP8226 Arduino based ePaper clock, using NTP and showing the weather.

Using a Waveshare 4.3" UART module and an ESP8226 R1 Mini from Jaycar Australia, which is a D1 Mini in the Arduino program.

The ESP8266 doesn't really have enough RAM to be able to parse the XML available from the Autralian Bureau of Meteorology, so the bom_xml.py script does that and spits out some simplified json I've put that json on my home web server, and set the script to run hourly.

Required Libraries

Timezone: https://github.com/JChristensen/Timezone

NTPClient: https://github.com/arduino-libraries/NTPClient

Connections

  • WakeUp -> D7
  • Reset - D8
  • DOUT -> D5
  • DIN -> D6

Creating Images for each digit

Use Images/create_images.py edit for font choice! The current images are in FreeMono.

Weather Icons

I have derived some from the Australian Bureau of Meteorology, Feel free to use those, or make some better ones!
