Overview

A Google Calendar Implementation for the InkPlate 6Color eInk display.

IMPORTANT: Before running the sketch - copy secrets.h.example to secrets.h and set wifi password etc in the secrets.h version.

It was originally based on the example calendar sketch for the InkPlate 6 Color but has been largely rewritten (aside from the display code). It has:

• Support for multiple calendars
• Support for calendars larger than RAM
• Support for all day events and (some) support for recurring events
• Support for filtering events

More details are in the ChangeLog

Details of some unit tests can be found in the test subdirectory

NOTE Need to use 7.2.1 of the inkplate boards. If using a newer board the linker throws errors around overflowing dram (nb: boards are different to libraries)

Debugging

• Can draw a calendar for a particular date by uncommenting example code in setup() in InkyCal.ino to (for example) debug weird behaviour on a particular date.

• When replicating on a computer what data we receive can do:

echo 'GET /calendar/ical/en.uk%23holiday%40group.v.calendar.google.com/public/basic.ics HTTP/1.1
Host: calendar.google.com

' | openssl s_client -quiet -connect calendar.google.com:443 2>/dev/null >/tmp/openssl.caldata
