 # e-inkCal
+
+this small script is supposed to be run on a raspberry pi with an SPI e-ink display attached to it.
+it will then display a weekcalendar on the e-ink display, which is fetched from a calDAV resource.

+ToDo:
+
+1. catching exceptions for caldav unauthorized
+2. options:
+    -w                  show week calendar
+    -m                  show month calendar
+
+3. include birthdays from another calendar
+4. make other views, e.g. month, day, year...
