Arduino/ESP32 software for an e-ink calendar, intended for use with iot-calendar-server.
Forked from kristiantm/eink-family-calendar-esp32, which details the hardware specs and required libraries for this project.
Sketch for LOLIN D32 is in /lolin32.
Earlier test sketches written for Arduino Nano 33 IoT are in /nano-test-local (processes locally) and /nano-test-remote (relies on iot-calendar-server).
Once you have installed the Adafruit GFX Library, you will need to copy the IOT Symbols font from /resources into the library's Fonts folder (on macOS, ~/Documents/Arduino/libraries/Adafruit_GFX_Library/Fonts). This draws the sun and moon icons. For the text fonts, you will need to edit the sketch to use the GFX library's standard fonts, or ones of your own making. (The font I use, the wonderful Metric from Klim Type Foundry, I am not licensed to share.)
