Lastly, it adds I2CDisplay as a display bus to talk over I2C. Particularly useful for the SSD1306. Fixes #1828. Fixes #1956 Add partial display update support. 2019-06-12T18:32:39+00:00 Scott Shawcroft scott@tannewt.org 2019-06-06T22:11:02+00:00 urn:sha1:eb21fc3e31790cee094d5c11811b55a57625340a Different operations to the display tree have different costs. Be aware of these costs when optimizing your code. * Changing tiles indices in a TileGrid will update an area covering them all. * Changing a palette will refresh every object that references it. * Moving a TileGrid will update both where it was and where it moved to. * Adding something to a Group will refresh each individual area it covers. * Removing things from a Group will refresh one area that covers all previous locations. (Not separate areas like add.) * Setting a new top level Group will refresh the entire display. Only TileGrid moves are optimized for overlap. All other overlaps cause sending of duplicate pixels. This also adds flip_x, flip_y and transpose_xy to TileGrid. They change the direction of the pixels but not the location. Fixes #1169. Fixes #1705. Fixes #1923. Make palette color ordering consistent with ColorConvertes and fix blinka. 2019-01-23T22:44:46+00:00 Scott Shawcroft scott@tannewt.org 2019-01-23T22:44:46+00:00 urn:sha1:b2f2abcb228be2bb4601a1373a307d98483ec274 Minor tweaks based on feedback 2018-09-06T21:49:49+00:00 Scott Shawcroft scott@tannewt.org 2018-09-06T21:49:49+00:00 urn:sha1:1683eb913d5bfb4265df56bf286d9971185a3a82 Introduce displayio to render graphics to displays. 2018-08-31T19:31:52+00:00 Scott Shawcroft scott@tannewt.org 2018-08-15T18:01:01+00:00 urn:sha1:6697544cdf87d0df5b761d401ad6ffe3a8d752fc It's designed to minimize RAM footprint by using Sprites to represent objects on the screen. The object model also facilitates partial screen updating which reduces the bandwidth needed to display. This is all handled in C. Python simply manipulates the objects with the ability to synchronize to frame timing.
