lady ada 8f1c25c8ae fix SH110x mode, the SH1107 is actually column not row mode BUT the SD1107 module we use is vertical orientation (confusing!) so row/col are NOT swapped. we will have to fix the SH1107 driver to match. this fix required for SH1106 (which uses the same page mode commands but ISNT rotated) 2021-06-06 18:25:40 -04:00

Jeff Epler 88d07ef35b displayio: further ensure just one start_terminal call
@cwalther determined that for boards with 2 displays (monster m4sk),
start_terminal would be called for each one, leaking supervisor heap
entries.

Determine, by comparing addresses, whether the display being acted on
is the first display (number zero) and do (or do not) call start_terminal.

stop_terminal can safely be called multiple times, so there's no need
to guard against calling it more than once.

Slight behavioral change: The terminal size would follow the displays[0]
size, not the displays[1] size

Jeff Epler b1592564b2 displayio: Fix matrixportal crash
An RGBMatrix has no bus and no bus_free method.  It is always possible
to refresh the display.

This was not a problem before, but the fix I suggested (#3449) added
a call to core_bus_free when a FramebufferDisplay was being refreshed.
This was not caught during testing.

This is a band-aid fix and it brings to light a second problem in which
a SharpDisplay + FrameBuffer will not have a 'bus' object, and yet does
operate using a shared SPI bus.  This kind of display will need a
"bus-free" like function to be added, or it can have problems like
#3309.

warriorofwire 206d0e598a Add vectorio: for drawing shapes
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.

Jeff Epler 7f744a2369 Supervisor: move most of systick to the supervisor
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
