It is enabled on:
* SAMD51 boards with 1MB flash (SKU ending in 20A)
* Feather RP2040 DVI. Others have PIO usb host.
* All ESP32 boards.
* All nRF boards
Fixes#8676
The guard against running when flash is disabled isn't perfect and
may lead to calling the row handler anyway. We were crashing due
to mp_hal_delay_us being in flash. So, move it to RAM.
Also move the panic handler to IRAM so we get nice output when this
happens.
Turn off JTAG by default so its pins can be used by code.py.
Fixes#8987
I tested this by fetching a .txt file repeatedly using curl while
running the fancy camera demo. (100+ times without failure). I also
repeatedly loaded the filesystem view http://.../fs/#/sd/ which worked
10+ times without failure, but does take some time (multiple seconds) to
show a listing with a few dozen files.
(I suspect there's an accidentally quadratic behavior in oofatfs to stat
every file in a directory, because it repeatedly does a linear search of
the directory for the stat information of each file, but that's not an
issue for Right Now(TM))
Closes: #8980
- add tuh_event_hook_cb() in SRAM, required when updated to latest tinyusb
- bump up pico-pio-usb to latest
- bump up tinyusb to latest for new tuh_hid_receive_abort(), and all endpoint abort when
SET_CONFIGURATION
Some ports implement their own protection against this at a low level
but it doesn't hurt to add it here instead.
Based on a patch from @drath42
Closes: #8788
Once the buffer has less that an endpoint's worth, TinyUSB won't
request more from the host. When that happens, ctrl-c will no
longer be sent to the device and TinyUSB won't find the wanted
character.
Fixes#4444
Greedily grab as much RMT memory as we can. It blocks other RMT
transmit channels but we only use it temporarily anyway. The more
we can grab, the fewer interrupts are needed to keep the transmit
going.
Flickers may still happen due to file system writes but most of the
time the animation just pauses.
On ESP32, move CircuitPython to the second core. This helps NeoPixel
by moving the RMT interrupt to the second core as well.
When testing ESP32 I noticed that settings.toml writes won't apply
until after hard reset. This removes that constraint but still
requires the password to enable the web workflow.
Fixes#3835
this means that the test for FLAG_CTRL together with FLAG_STRING is
not needed. Instead, the FLAG_STRING | FLAG_CTRL row, when
encountered earlier, will automatically take precedence.
Added the ability to work with the function keys f1-f12, ctrl-left, ctrl-right, ctrl-up, ctrl-down, page down, page up, insert, delete, pause. in the format of command VT 100
This changes storage.mount() to require that a mount point exist
on the parent file system.
A bug in background tasks is also fixed where the function
parameter is cleared on pending callbacks during "reset".
Disk usage is shown on the directory listing and changes based on
the mounted file system. Writable is also loaded per-directory.
Fixes#8108. Fixes#8690. Fixes#8107.
* Disable Nagle at the end of error messages so they are sent before
the socket is closed.
* Correctly discard file contents when the PUT file is too large.
* Correctly reset file size after failure to setting it too large.
* Change diskinfo.json to be list of disks in preparation of supporting
multiple disks.
* Bump version to 3 for the above change.
* Document diskinfo.json.
Fixes#8109
This simplifies allocating outside of the VM because the VM doesn't
take up all remaining memory by default.
On ESP we delegate to the IDF for allocations. For all other ports,
we use TLSF to manage an outer "port" heap. The IDF uses TLSF
internally and we use their fork for the other ports.
This also removes the dynamic C stack sizing. It wasn't often used
and is not possible with a fixed outer heap.
Fixes#8512. Fixes#7334.
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.
These are moved:
* Display -> busdisplay.BusDisplay
* FourWire -> fourwire.FourWire
* EPaperDisplay -> epaperdisplay.EPaperDisplay
* I2CDisplay -> i2cdisplaybus.I2CDisplayBus
`paralleldisplay` is now `paralleldisplaybus` (and registered as
`paralleldisplay` too).
Bus related helpers are split out of display_core into bus_core.
It is in still displayio since it is a dependency of both
busdisplay and epaperdisplay.
Fixes#7667
