TrueGray-PNG
Description
!!!Requires Firmware 2.0 (note:flickers on newest BETA4, working on fix). !!!
developer.getpebble.com/2
Pebble smartwatch app using Pulse-Width-Modulation and Framebuffer tricks to render grayscale PNGs to Pebble E-Paper Black and White display.
Uses uPNG for native PNG support with 2-bit Grayscale. Example of images here: github.com/pebble-hacks/pebble-truegray-png/tree/master/resources
Useful in games for 1 extra color (gray), can avoid the uPNG code and just create and use a 2-bit framebuffer for rendering.
Notice: Constantly updating the screen, so it does consume more power than usual. ie. Not to be used for watchfaces.
