This removes the limit on data coming in from a BLE.gattc_read() request,
or a notify with payload (coming in to a central). In both cases the data
coming in to the BLE callback is now limited only by the available data in
the ringbuf, whereas before it was capped at (default hard coded) 20 bytes.
Instead of enqueue_irq() inspecting the ringbuf to decide whether to
schedule the IRQ callback (if ringbuf is empty), maintain a flag that knows
if the callback is on the schedule queue or not. This saves about 150
bytes of code (for stm32 builds), and simplifies all uses of enqueue_irq()
and schedule_ringbuf().
qstrs in this file are always included in all builds, even if not used
anywhere. So remove those that are never needed, and make USB names
conditional on having USB enabled.
With the memcpy() call placed last it avoids the effects of registers
clobbering. It's definitely effective in non-inlined functions, but even
here it is still making a small difference. For example, on stm32, this
saves an extra `ldr` instruction to load `o->vstr` after the memcpy()
returns.
The string length being longer than the allowed qstr length can happen in
many locations, for example in the parser with very long variable names.
Without an explicit check that the length is within range (as done in this
patch) the code would exhibit crashes and strange behaviour with truncated
strings.
And return -MP_EIO if calling storage_read_block/storage_write_block fails.
This lines up with the return type and value (negative for error) of the
calls to MICROPY_HW_BDEV_READBLOCKS (and WRITEBLOCKS, and BDEV2 versions).
The pyb.Flash() class can now be used to construct objects which reference
sections of the flash storage, starting at a certain offset and going for a
certain length. Such objects also support the extended block protocol.
The signature for the constructor is: pyb.Flash(start=-1, len=-1).
This commit refactors and generalises the boot-mount routine on stm32 so
that it can mount filesystems of arbitrary type. That is, it no longer
assumes that the filesystem is FAT. It does this by using mp_vfs_mount()
which does auto-detection of the filesystem type.
The address, adv payload and uuid fields of the event are pre-allocated by
modbluetooth, and reused in the IRQ handler. Simplify this and move all
storage into the `mp_obj_bluetooth_ble_t` instance.
This now allows users to hold on to a reference to these instances without
crashes, although they may be overwritten by future events. If they want
to hold onto the values longer term they need to copy them.
Using mp_hal_delay_ms allows the scheduler to run, which might result in
another transmit operation happening, which would bypass the sleep (and
fail). Use mp_hal_delay_us instead.
The compile-time configuration value MICROPY_HW_RTC_USER_MEM_MAX can now be
used to define the amount of memory set aside for RTC.memory(). If this
value is configured to zero then the RTC.memory functionality is not
included in the build.
Remove existing scan result events from the ringbuf if the ringbuf is full
and we're trying to enqueue any other event. This is needed so that events
such as SCAN_COMPLETE are always put on the ringbuf.
The IDF heap is more fragmented with IDF 4 and mbedtls cannot allocate
enough RAM with 16+16kiB for both in and out buffers, so reduce output
buffer size.
Fixes issue #5303.
This commit removes the Makefile-level MICROPY_FATFS config and moves the
MICROPY_VFS_FAT config to the Makefile level to replace it. It also moves
the include of the oofatfs source files in the build from each port to a
central place in extmod/extmod.mk.
For a port to enabled VFS FAT support it should now set MICROPY_VFS_FAT=1
at the level of the Makefile. This will include the relevant oofatfs files
in the build and set MICROPY_VFS_FAT=1 at the C (preprocessor) level.
defindex.html (used by topindex.html) is deprecated, but topindex.html was
already identical other than setting the title, so just inherit directly
from layout.html.
