So that the flash size can be changed in just one place. Also remove the
duplicate cache entry.
|
|
Updates the zephyr port to use the ZEPHYR_BASE environment variable only to
locate the zephyr cmake package, allowing cmake to cache the variable.
|
|
The minimum required cmake version has been 3.13.1 since zephyr 1.14.0.
|
|
Converts DT_FLASH_AREA usages in the zephyr port to new device tree macros
introduced in zephyr 2.3.
Tested with littlefs on the reel_board.
|
|
Updates the zephyr port to use the new timeout api introduced in zephyr
2.3.
|
|
Updates the zephyr port to use refactored device structures introduced in
zephyr 2.3.
|
|
Zephyr renamed CONFIG_FLOAT to CONFIG_FPU to better reflect its semantics
of enabling the hardware floating point unit (FPU) rather than enabling
toolchain-level floating point support (i.e., software floating point for
FPU-less socs).
|
|
Zephyr deprecated and then removed its stack_analyze function because it
was unsafe. Use the new zephyr thread analyzer instead and rename the
MicroPython function to zephyr.thread_analyze() to be more consistent with
the implementation.
Tested on mimxrt1050_evk.
The output now looks like this:
>>> zephyr.thread_analyze()
Thread analyze:
80004ff4 : unused 400 usage 112 / 512 (21 %)
rx_workq : unused 1320 usage 180 / 1500 (12 %)
tx_workq : unused 992 usage 208 / 1200 (17 %)
net_mgmt : unused 656 usage 112 / 768 (14 %)
sysworkq : unused 564 usage 460 / 1024 (44 %)
idle : unused 256 usage 64 / 320 (20 %)
main : unused 2952 usage 1784 / 4736 (37 %)

Do not use the traditional C heap in order to save memory, because the
traditional C heap is unused in MicroPython.

This patch adds quickref documentation for the change in commit
afd0701bf7a9dcb50c5ab46b0ae88b303fec6ed3. This commit added the ability to
disable the REPL and hence use UART0 for serial communication on the
esp8266, but was not previously documented anywhere.
The text is largely taken from the commit message, with generic information
on using the UART duplicated from the Wipy quickref document.

For example, to run the BLE multitests entirely with the unix port:
env MICROPY_MICROPYTHON=../ports/unix/micropython-dev ./run-multitests.py \
-i micropython,MICROPYBTUSB=01 \
-i micropython,MICROPYBTUSB=02:02 \
multi_bluetooth/ble_*.py
|
|
This allows running (for example):
env MICROPYBTUSB=2-2 ./micropython-dev ../../examples/bluetooth/ble_temperature_central.py
|
|
|
|
This is for the NimBLE bindings, to make sure the default GATT service
appears and that the esp32 initialises NimBLE correctly (it now matches
stm32).

Fixes issue #6107.

Long ago, prior to 0ef01d0a75b8b2f48a72f0041e048a390b9e75b6, fixed and
ordered maps were the same setting with the "table_is_fixed_array" member
of mp_map_t. But these settings are actually independent, and it is
possible to have is_fixed=1, is_ordered=0 (although this can currently
only be done by tools/cc1). So update the comments to reflect this.
|
|
The resulting dict is now marked as read-only (is_fixed=1) to enforce the
fact that changes to this dict will not be reflected in the class instance.
This commit reduces code size by about 20 bytes, and should be more
efficient because it creates a direct copy of the dict rather than
reinserting all elements.
|
|
The behavior mirrors the instance object dict attribute where a copy of the
local attributes are provided (unless the dict is read-only, then that dict
itself is returned, as an optimisation). MicroPython does not support
modifying this dict because the changes will not be reflected in the class.
The feature is only enabled if MICROPY_CPYTHON_COMPAT is set, the same as
the instance version.

Saves about 500 bytes on unix x64 and enables CPython-conform
usage of passing a re object to these functions.
|
|
|
|
Sending more than 64 bytes to the USB CDC endpoint in HS mode will lead to
a hard crash. This commit fixes the issue, although there may be a better
fix from upstream TinyUSB in the future.
|
|
This enables warnings as errors and fixes all current errors, namely:
- reference to terms in the glossary must now be explicit (:term:)
- method overloads must not be declared as a separate method or must
use :noindex:
- 2 cases where `` should have been used instead of `

This builds docs, but only on pull requests that change a file in the
docs/ directory.

|
With this commit the code should work correctly regardless of the size of
StackType_t (it's actually 1 byte in size for the esp32's custom FreeRTOS).
Fixes issue #6072.
|
|
Fixes issue #6095.

According to Supplement to the Bluetooth Core Specification v8 Part A
1.3.1, to support BR/EDR the code should set the fifth bit (Simultaneous LE
and BR/EDR to Same Device Capable (Controller)) and fourth bit
(Simultaneous LE and BR/EDR to Same Device Capable (Host)) of the flag.
|
|
The ring buffer previously used a single unsigned byte field to save the
length, meaning that it would overflow for large characteristic value
responses.
With this commit it now use a 16-bit length instead and has code to
explicitly truncate at UINT16_MAX (although this should be impossible to
achieve in practice).
|
|
This commit makes sure that all discovery complete and read/write status
events set the status to zero on success.
The status value will be implementation-dependent on non-success cases.
|
|
|
|
Updates the tests to use non-bitmask events, event renames, as well as some
of the new completion events to improve reliability of the tests.
|
|
On btstack there's no status associated with the read result, it comes
through as a separate event. This allows you to detect read failures or
timeouts.
|
|
In most situations this is a more efficient way of going straight to the
service and characteristic you need.
|
|
Without this it's difficult to implement a state machine correctly if the
desired services are not found.
|
|
There doesn't appear to be any use for only triggering on specific events,
so it's just easier to number them sequentially. This makes them smaller
values so they take up only 1 byte in the ringbuf, only 1 byte for the
opcode in the bytecode, and makes room for more events.
Also add a couple of new event types that need to be implemented (to avoid
re-numbering later).
And rename _COMPLETE and _STATUS to _DONE for consistency.
In the future the "trigger" keyword argument can be reinstated by requiring
the user to compute the bitmask, eg:
ble.irq(handler, 1 << _IRQ_SCAN_RESULT | 1 << _IRQ_SCAN_DONE)

This commit implements an LED class with rudimentary parts of a pin C API
to support it. The LED class does not yet support setting an intensity.
This LED class is put in the machine module for the time being, until a
better place is found.
One LED is supported on TEENSY40 and MIMXRT1010_EVK boards.

Changes are:
- string0 is no longer built when building for host as the target, because
it'll be provided by the system libc and may in some cases clash with the
system one (eg on OSX).
- mp_int_t/mp_uint_t are defined in terms of intptr_t/uintptr_t to support
both 32-bit and 64-bit builds.
- Configuration values which are the default in py/mpconfig.h are removed
from mpconfigport.h to make the configuration a bit more minimal, eg as
a better starting point for new ports.

Fixes issue #6089.

Fixes #3116.
|

New releases have moved from launchpad to developer.arm.com.
|
|
These features are now supported (although machine.ADC is recommended over
pyb.ADC).
|

|
|
For now SYSCLK cannot be changed and must remain at 64MHz.
|
|
Just disallow changing the rxbuf which will be some static RAM (can't free
it and soft-reset would lose any dynamically allocated buffer).
