Enable title bar on all builds
* Tweak scroll area position so last line is complete and top is
  under the title bar.
* Pick Blinka size based on the font to minimize unused space in
  title bar. Related to #2791
* Update the title bar after terminal is started. Fixes #6078

Wi-Fi autoconnect and title bar status
This adds support for CIRCUITPY_WIFI_SSID and CIRCUITPY_WIFI_PASSWORD
in `/.env`. When both are defined, CircuitPython will attempt to
connect to the network even when user code isn't running. If the
user code attempts to a network with the same SSID, it will return
immediately. Connecting to another SSID will disconnect from the
auto-connected network. If the user code initiates the connection,
then it will be shutdown after user code exits. (Should match <8
behavior.)

This PR also reworks the default displayio terminal. It now supports
a title bar TileGrid in addition to the (newly renamed) scroll area.
The default title bar is the top row of the display and is positioned
to the right of the Blinka logo when it is enabled. The scroll area
is now below the Blinka logo.

The Wi-Fi auto-connect code now uses the title bar to show its
state including the IP address when connected. It does this through
the "standard" OSC control sequence `ESC ] 0 ; <s> ESC \` where <s>
is the title bar string. This is commonly supported by terminals
so it should work over USB and UART as well.

Radomir Dopieralski 93ea1bd9bd Add a flag for removing the Blinka logo from the REPL
There may be several reasons why we might want to remove the logo form
the REPL: a fork of CircuitPython that doesn't have the right to use the
logo, an especially small display that needs all the room it has to be
useful, displays that are especially vulnerable to burn-in, maybe even
the smaller chips where we want to save as much flash memory as
possible.

Initial broadcom port for Raspberry Pi
This targets the 64-bit CPU Raspberry Pis. The BCM2711 on the Pi 4
and the BCM2837 on the Pi 3 and Zero 2W. There are 64-bit fixes
outside of the ports directory for it.

There are a couple other cleanups that were incidental:
* Use const mcu_pin_obj_t instead of omitting the const. The structs
  themselves are const because they are in ROM.
* Use PTR <-> OBJ conversions in more places. They were found when
  mp_obj_t was set to an integer type rather than pointer.
* Optimize submodule checkout because the Pi submodules are heavy
  and unnecessary for the vast majority of builds.

Add ability to disable BLE workflow
Call `supervisor.disable_ble_workflow()` and the BLE workflow will
be disabled until the chip is reset.

This also includes a couple fixes:
1. Terminals can now be deinit by setting the tilegrid to NULL. This
  prevents using the tilegrid before display is init.
2. Fix BLE serial send amount when sending more than a single packet.

Radomir Dopieralski 121c6bcc9b Replace displaio.Group.children with a python list
This is a first go at it, done by naive replacing of all array
operations with corresponding operations on the list. Note that
there is a lot of unnecessary type conversions, here. Also, list_pop
has been copied, because it's decalerd STATIC in py/objlist.h

Radomir Dopieralski 6e0ce23f3e displaio: don't store group children native object
Since we want to expose the list of group's children to the user,
we should only have the original objects in it, without any other
additional data, and compute the native object as needed.

Christian Walther 2ba9805f84 Use movable allocation system for terminal tilegrid.
Moving memory is now done by the infrastructure and neither necessary nor correct here anymore.
2020-11-28 17:54:34 +01:00
Christian Walther c7404a3ff8 Add movable allocation system.
This allows calls to `allocate_memory()` while the VM is running, it will then allocate from the GC heap (unless there is a suitable hole among the supervisor allocations), and when the VM exits and the GC heap is freed, the allocation will be moved to the bottom of the former GC heap and transformed into a proper supervisor allocation. Existing movable allocations will also be moved to defragment the supervisor heap and ensure that the next VM run gets as much memory as possible for the GC heap.

By itself this breaks terminalio because it violates the assumption that supervisor_display_move_memory() still has access to an undisturbed heap to copy the tilegrid from. It will work in many cases, but if you're unlucky you will get garbled terminal contents after exiting from the vm run that created the display. This will be fixed in the following commit, which is separate to simplify review.

Jeff Epler 331aa6e59f displayio: When the display is tall, move blinka above the text
This makes a more useful display on the portrait magtag, allowing 21
characters across instead of just 18.  There are 20 full rows of text,
instead of 21.  The total number of characters increases slightly from 378
to 420.

For comparison, the Commodore VIC 20 had 22 rows of 23 characters for a
total of 506 characters. :-P

Turn off terminalio for ja and ko
The font is missing many characters and the build needs the space.
We can optimize font storage when we get a good font.

The serial output will work as usual.

Add support for grayscale displays that are < 8 bit depth.

Lastly, it adds I2CDisplay as a display bus to talk over I2C. Particularly
useful for the SSD1306.

Add partial display update support.
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.

Rework the pixel computation to use areas
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.

Set the terminal tilegrid NULL after free
Without this, a double free can occur when a display (and terminal)
is released and then a crash occurs. Upon a second release,
different memory is released (sometimes the heap). When this is
followed by an allocation for the flash cache, the cache can
overwrite the active heap causing crashes.

A variety of displayio improvements
This changes a number of things in displayio:
* Introduces BuiltinFont and Glyph so the built in font can be used by libraries. For boards with
  a font it is available as board.TERMINAL_FONT. Fixes #1172
* Remove _load_row from Bitmap in favor of bitmap[] access. Index can be x/y tuple or overall index. Fixes #1191
* Add width and height properties to Bitmap.
* Add insert and [] access to Group. Fixes #1518
* Add index param to pop on Group.
* Terminal no longer takes unicode character info. It takes a BuiltinFont instead.
* Fix Terminal's handling of [###D vt100 commands used when up arrowing into repl history.
* Add x and y positions to Group plus scale as well.
* Add bitmap accessor for BuiltinFont
