Espressif's Characteristics allocate memory that may be on the
supervisor heap. We need to free it when stopping BLE workflow.
Otherwise, we leak the memory and eventually safe mode.
Fixes#9599
Enable BLE where we can. Switch 4MB, non-USB board default partitioning
over to a single 2MB firmware bank. Old boards override this setting to
keep the same behavior.
This also adds alpha support for the ESP32-C2 (aka ESP8684).
Fixes#5926 and fixes#7170
We mark all protocols with their type using MP_PROTO_IMPLEMENT,
and checking in mp_get_stream{,_raise}.
This was not turning up as a problem in tests until a (new, not yet
commited) change to jpegio caused a segfault because a type implementing
a different protocol was passed in to mp_get_stream.
By using 0 (instead of MP_QSTR_protocol_stream) as the marker for
objects implementing the standard micropython stream protocol, the
number of CIRCUITPY-CHANGEs is minimized.
micropython puts the pointer-ness into the typedef; we can put the
const-ness there too.
this reduces the delta to micropython; for instance, emitinlinextensa
and emitinlinethumb now match upstream.
This 2-in-1 PR started with the goal of support the Bangle.js 2
smartwatch with *no USB*.
* Adds "secure" DFU build support with a committed private key.
* Adds 3-bit color support with one dummy bit for the JDI memory display
* Allows nrf boards to have a board_background_task() run in RUN_BACKGROUND_TASK.
This is needed because the Bangle.js 2 uses the watchdog to reset.
* Renamed port_background_task() to port_background_tick() to indicate it
runs on tick, not RUN_BACKGROUND_TASK.
* Marks serial connected when the display terminal is inited. This means
that safe mode messages show up on the display.
ACep, 7-color epaper displays also pack 3 bits in 4. So, I added that
support as well.
* Adds 3-bit ACeP color support for 7-color e-paper displays. (Not
watch related but similar due to color depth.)
* Allows a refresh sequence instead of a single int command. The 7" ACeP
display requires a data byte for refresh.
* Adds optional delay after resetting the display. The ACeP displays
need this. (Probably to load LUTs from flash.)
* Adds a cleaning phase for ACeP displays before the real refresh.
For both:
* Add dither support to Palette.
* Palette no longer converts colors when set. Instead, it caches
converted colors at each index.
* ColorConverter now caches the last converted color. It should make
conversions faster for repeated colors (not dithering.)
We adopted the file "py/ioctl.h" and the ioctl names beginning
with MP_IOCTL_POLL while micropython went with "py/stream.h" and
MP_STREAM_POLL.
Align with upstream.
Closes#6711
Originally, black_bindings found each contiguous "//|" block and sent
it to black independently. This was slower than it needed to be.
Instead, swap the comment prefix: when running black, take off
"//|" prefixes and put "##|" prefixes on all un-prefixed lines.
Then, after black is run, do the opposite operation
This more than doubles the overall speed of "pre-commit run --all",
from 3m20s to 55s CPU time on my local machine (32.5s to under 10s
"elapsed" time)
It also causes a small amount of churn in the bindings, because
black now sees enough context to know whether one 'def' follows another
or ends the 'def's in a 'class'. In the latter case, it adds an extra
newline, which becomes a "//|" line.
I'm less sure why a trailing comma was omitted before down in
rp2pio/StateMachine.c but let's roll with it.
This lets the BLE stack run through the wait period after a VM run
when it may be waiting for more writes due to an auto-reload.
User BLE functionality will have their events stopped. Scanning and
advertising is also stopped.
