Otherwise, button presses might not be noticed.

vectorio: fix up Rectangle

2020-05-10T23:21:07+00:00

* Fix drawing 1 pixel too large * Need to pad dirty area to ensure removed shapes are fully removed

vectorio: clean up after group removal

2020-05-10T22:36:23+00:00

VectorShape tells the Group to redraw whatever it left behind when it is removed now.

vectorio: respect display transpose and mirror.

2020-05-10T21:18:13+00:00

VectorShape now just uses the Group's and Display's absolute transforms.

vectorio: switch per-shape transform to Display

2020-05-10T05:15:51+00:00

Rather than maintain a transform per-shape, we'll just use whatever settings are on the Display. Currently only transpose is done.

Add vectorio: for drawing shapes

2020-05-09T22:38:22+00:00

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.

aesio: add basic AES encryption and decryption

2020-05-06T09:40:06+00:00

This adds initial support for an AES module named aesio. This implementation supports only a subset of AES modes, namely ECB, CBC, and CTR modes. Example usage: ``` >>> import aesio >>> >>> key = b'Sixteen byte key' >>> cipher = aesio.AES(key, aesio.MODE_ECB) >>> output = bytearray(16) >>> cipher.encrypt_into(b'Circuit Python!!', output) >>> output bytearray(b'E\x14\x85\x18\x9a\x9c\r\x95>\xa7kV\xa2`\x8b\n') >>> ``` This key is 16-bytes, so it uses AES128. If your key is 24- or 32- bytes long, it will switch to AES192 or AES256 respectively. This has been tested with many of the official NIST test vectors, such as those used in `pycryptodome` at https://github.com/Legrandin/pycryptodome/tree/39626a5b01ce5c1cf51d022be166ad0aea722177/lib/Crypto/SelfTest/Cipher/test_vectors/AES CTR has not been tested as NIST does not provide test vectors for it.
