Overview

How I got started with Pebble

• Got first batch Pebble • SDK was still “young” • I am not a designer… • Got Pebble Time from Kickstarter • Met designer in reddit • Calendar Cards was born

Calendar Cards• Show next event from

Google Calendar • Weather based on your

• Event list retrieval from main Calendar

• Next event received and shown in the face

How Timeline animation works

First approach: BitmapLayer and animation Current approach: • Load Bitmap in memory • Use gbitmap_create_as_sub_bitmap and

graphics_draw_bitmap_in_rect • Move 2 sub-bitmaps around to do scrolling • Change pixel colors to match the one selected in
