2021-03-18displayio: area: add displayio_area_canonJeff Epler
This routine will be used to simplify code that deals with ranges of bitmap coordinates.
2021-03-18displayio: area: add displayo_area_copy_coords, displayio_area_emptyJeff Epler
.. and simplify the implmentation of displayio_area_union This _slightly_ changes the behavior of displayio_area_union: Formerly, if one of the areas was empty, its coordinates were still used in the min/max calculations. Now, if one of the areas is empty, the result gets the other area's coords In particular, taking the union of the empty area with coords (0,0,0,0) with the non-empty area (x1,y1,x2,y2) would give the area (0,0,x2,y2) before, and (x1,y1,x2,y2) after the change.

2020-07-20framebufferio: Handle auto refresh flag at resetJeff Epler
if we don't set the flag via accessor fn the tick enable might become wrong
2020-04-17RGBMatrix: finish renaming from ProtomatterJeff Epler
This gets all the purely internal references. Some uses of protomatter/Protomatter/PROTOMATTER remain, as they are references to symbols in the Protomatter C library itself.
2020-04-14protomatter: release the protomatter object during release_displays()Jeff Epler
2020-04-14fix build for non-displayio & non-protomatter targetsJeff Epler
2020-04-14protomatter: more memory allocation fixesJeff Epler
- bump supervisor alloc count by 4 (we actually use 5) - move reconstruct to after gc heap is reset - destroy protomatter object entirely if not used by a FramebufferDisplay - ensure previous supervisor allocations are released - zero out pointers so GC can collect them

2019-08-22Refresh ePaper displays once code.py is done runningScott Shawcroft
2019-08-22Rework refresh API and factor common display stuff outScott Shawcroft
NOT TESTED! Just compiles Fixes #1691

2019-08-22EPaper displays work mostly.Scott Shawcroft
2019-08-14Fix I2CDisplay lifecycle and splash lifecycle.Scott Shawcroft
Fixes https://github.com/adafruit/Adafruit_CircuitPython_DisplayIO_SSD1306/issues/2
2019-07-25Add knobs for SSD1322 and two fixes.Scott Shawcroft
* Fix terminal clear after first successful code.py run. * Fix transmitting too many bytes for column constraint with single byte bounds.
2019-07-19Add support for grayscale displays that are < 8 bit depth.Scott Shawcroft
This also improves Palette so it stores the original RGB888 colors. Lastly, it adds I2CDisplay as a display bus to talk over I2C. Particularly useful for the SSD1306. Fixes #1828. Fixes #1956
2019-06-12Add partial display update support.Scott Shawcroft
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.

2019-05-22Make point 2 in areas exclusive and simplify full_coverage.Scott Shawcroft
2019-05-21Rework the pixel computation to use areasScott Shawcroft
This changes the displayio pixel computation from per-pixel to per-area. This is precursor work to updating portions of the screen (#1169). It should provide mild speedups because bounds checks are done once per area rather than once per pixel. Filling by area also allows TileGrid to maintain a row-associative fill pattern even when the display's refresh is orthogonal to it.

2019-04-05Fix crash when getting board.SPI outside the VMScott Shawcroft
If one of the default pins was already in use it would crash. The internal API has been refined to allow us to get the value without causing an init of the singleton. Fixes #1753

display. Clarify code. Handle multiple displays better.

2019-02-01Add support for display rotation and raw commandsScott Shawcroft
Display rotation is relative to the scan order of the display. The scan order can be found by scrolling the display with command 0x37 `display_bus.send(0x37, struct.pack(">H", i % 128))` Fixes #1504
