This can be enforced by pre-commit, but correct it separately to make it easier to review.
2020-05-10vectorio: clean up after group removalwarriorofwire
VectorShape tells the Group to redraw whatever it left behind when it is removed now.
2020-05-10vectorio: respect display transpose and mirror.warriorofwire
VectorShape now just uses the Group's and Display's absolute transforms.
2020-05-09vectorio: switch per-shape transform to Displaywarriorofwire
Rather than maintain a transform per-shape, we'll just use whatever settings are on the Display. Currently only transpose is done.
2020-05-09Add vectorio: for drawing shapeswarriorofwire
vectorio builds on m4 express feather Concrete shapes are composed into a VectorShape which is put into a displayio Group for display. VectorShape provides transpose and x/y positioning for shape implementations. Included Shapes: * Circle - A radius; Circle is positioned at its axis in the VectorShape. - You can freely modify the radius to grow and shrink the circle in-place. * Polygon - An ordered list of points. - Beteween each successive point an edge is inferred. A final edge closing the shape is inferred between the last point and the first point. - You can modify the points in a Polygon. The points' coordinate system is relative to (0, 0) so if you'd like a top-center justified 10x20 rectangle you can do points [(-5, 0), (5, 0), (5, 20), (0, 20)] and your VectorShape x and y properties will position the rectangle relative to its top center point * Rectangle A width and a height.

This isn't perfect and needs a bit more testing.
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.
2020-04-17Rename Protomatter -> RGBMatrixJeff Epler
This is a quick rename, it changes the user-facing names but not the internal names of things.
2020-04-17Rename _protomatter -> protomatterJeff Epler
I originally believed that there would be a wrapper library around it, like with _pixelbuf; but this proves not to be the case, as there's too little for the library to do.

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

2020-03-25Add polarity and phase to FourWire.Scott Shawcroft
It was fixed as 0/0 even though it used to get it from the current SPI state. This makes it more explicit with kwargs. Thanks to magpie_lark and kmatocha on the Adafruit Support forum for finding the issue: https://forums.adafruit.com/viewtopic.php?f=60&t=162515

2019-11-26Fix ePaper so it works after a GC.Scott Shawcroft
We weren't correctly collecting the start and stop sequences. As a result, the GC would free the space and allocate other info there. Thanks to JacobT on Discord for the bug report!
2019-11-18Supervisor: move most of systick to the supervisorJeff Epler
This code is shared by most parts, except where not all the #ifdefs inside the tick function were present in all ports. This mostly would have broken gamepad tick support on non-samd ports. The "ms32" and "ms64" variants of the tick functions are introduced because there is no 64-bit atomic read. Disabling interrupts avoids a low probability bug where milliseconds could be off by ~49.5 days once every ~49.5 days (2^32 ms). Avoiding disabling interrupts when only the low 32 bits are needed is a minor optimization. Testing performed: on metro m4 express, USB still works and time.monotonic_ns() still counts up
