Combined 36 and 72px (and now 120px) version of SmartPoi ESP8266 firmware Works well on D1 mini and OK on ESP-01
see circusscientist.com for details on how to get this to work
DOCUMENTATION: https://tomjuggler.github.io/SmartPoi-Firmware/html/ *please note that this is a very old project, based on code I did 10 years ago while learning C++. It's messy!
To upload images and control the poi please see smartpoi-js-utilities (works in a browser)
Under active development
Coming soon: "Magic Poi" for ESP32 - see http://magicpoi.circusscientist.com
