In this tutorial, I am sharing Cale-IDF library that is used to let ESP32 interface e-Paper over SPI and connect at the same time to cale.es web server to derive display frame data.

The firmware is designed to manage the e-Paper and let the ESP32 enter deep sleep mode to reduce power consumption for a period that can be configured remotely from cale.es web server.

cale.es server makes it possible to manage the e-Paper screen frame remotely and let it show useful information like weather status, personal google calendar or event Bitcoin price chart.
