While this console API improves handling on real hardware boards
(e.g. clipboard paste is much more reliable, as well as programmatic
communication), it vice-versa poses problems under QEMU, apparently
because it doesn't emulate UART interrupt handling faithfully. That
leads to inability to run the testsuite on QEMU at all. To work that
around, we have to suuport both old and new console routines, and use
the old ones under QEMU.
We want to close communication object even if there were exceptions
somewhere in the code. This is important for --device exec:/execpty:
which may otherwise leave processing running in the background.
Ideally, these should be configurable from Python (using network module),
but as that doesn't exist, we better off using Zephyr's native bootstrap
configuration facility.
The poweroff() and poweron() methods are used to do soft power control of
the display, and this patch makes these methods work the same for both I2C
and SPI interfaces.
Backport of micro:bit random module.
Plugged into the port as a general random module for all nrf51/nrf52 targets. Works both with and without Bluetooth LE stack enabled.
Behavioral change: seed() method has been removed, as the use of RNG peripheral generates true random sequences and not pseudo-random sequences.
The driver also takes care of calling the Bluetooth LE stack for random values if the stack is enabled. The reason for this is that the Bluetooth LE stack take ownership of the NRF_RNG when enabled. Tolerate to enable/disable on the fly, and will choose to use direct access to the peripheral if Bluetooth LE stack is disabled or not compiled in at all.
Driver has been included in the top Makefile, and will not be compiled in unless nrf51_hal_conf.h/nrf52_hal_conf.h defines HAL_RNG_MODULE_ENABLED (1).
* nrf: Adding Arduino Primo board support
* nrf: Adding arduino_primo to target boards table in readme.md
* nrf/boards: Activating pyb.LED module for arduino_primo board.
* nrf/boards: Removing define not needed for arduino_primo
Updating arduino_primo board mpconfigboard.h. Removing a define
that was wrongly named. Instead of renaming it, it was removed as
it was never used.
Duplicating pattern for detecting location of libm, libc and libgcc
from teensy port. Activating MICROPY_FLOAT_IMPL (FLOAT) for nrf52 targets
and adding libs into the compile. For nrf51 targets it is still set to
NONE as code grows to much (about 30k).
Some numbers on flash use if MICROPY_FLOAT_IMPL is set to
MICROPY_FLOAT_IMPL_FLOAT and math libraries are enabled (lgcc, lc, lm).

Printing "(null)" when a NULL string pointer is passed to %s is a debugging
feature and not a feature that's relied upon by the code. So it only needs
to be compiled in when debugging (such as assert) is enabled, and saves
roughy 30 bytes of code when disabled.
This patch also fixes this NULL check to not do the check if the precision
is specified as zero.
Header files that are considered internal to the py core and should not
normally be included directly are:
py/nlr.h - internal nlr configuration and declarations
py/bc0.h - contains bytecode macro definitions
py/runtime0.h - contains basic runtime enums
Instead, the top-level header files to include are one of:
py/obj.h - includes runtime0.h and defines everything to use the
mp_obj_t type
py/runtime.h - includes mpstate.h and hence nlr.h, obj.h, runtime0.h,
and defines everything to use the general runtime support functions
Additional, specific headers (eg py/objlist.h) can be included if needed.
Qstr values fit in 16-bits (and this fact is used elsewhere in the code) so
no need to use more than that for the large lookup tables. The compiler
will anyway give a warning if the qstr values don't fit in 16 bits. Saves
around 80 bytes of code space for Thumb2 archs.
Building mpy-cross: this patch adds .exe to the PROG name when building
executables for host (eg mpy-cross) on Windows. make clean now removes
mpy-cross.exe under Windows.
Building MicroPython: this patch sets MPY_CROSS to mpy-cross.exe or
mpy-cross so they can coexist and use cygwin or WSL without rebuilding
mpy-cross. The dependency in the mpy rule now uses mpy-cross.exe for
Windows and mpy-cross for Linux.
CPython docs explicitly state that the RHS of a set/frozenset binary op
must be a set to prevent user errors. It also preserves commutativity of
the ops, eg: "abc" & set() is a TypeError, and so should be set() & "abc".
This change actually decreases unix (x64) code by 160 bytes; it increases
stm32 by 4 bytes and esp8266 by 28 bytes (but previous patch already
introduced a much large saving).
A lot of set's methods (the mutable ones) are not allowed to operate on a
frozenset, and giving frozenset a separate locals dict with only the
methods that it supports allows to simplify the logic that verifies if
args are a set or a frozenset. Even though the new frozenset locals dict
is relatively large (88 bytes on 32-bit archs) there is a much bigger
saving coming from the removal of a const string for an error message,
along with the removal of some checks for set or frozenset type.
Changes in code size due to this patch are (for ports that changed at all):
unix x64: -56
unix nanbox: -304
stm32: -64
esp8266: -124
cc3200: -40
Apart from the reduced code, frozenset now has better tab-completion
because it only lists the valid methods. And the error message for
accessing an invalid method is now more detailed (it includes the
method name that wasn't found).
* atmel-samd: Support patching after updating ASF4.
This makes it possible to automatically fix newer code.
* atmel-samd: Update ASF4 to include flash APIs for SAMD51.
This is the first automatic update that has caused a few deletions
where code was previously copied instead of moved.
This is a prerequisite for #260.
This returns a complex number, following CPython behaviour. For ports that
don't have complex numbers enabled this will raise a ValueError which gives
a fail-safe for scripts that were written assuming complex numbers exist.
This adds a new configuration option to print runtime warnings and errors to
stderr. On Unix, CPython prints warnings and unhandled exceptions to stderr,
so the unix port here is configured to use this option.
The unix port already printed unhandled exceptions on the main thread to
stderr. This patch fixes unhandled exceptions on other threads and warnings
(issue #2838) not printing on stderr.
Additionally, a couple tests needed to be fixed to handle this new behavior.
This is done by also capturing stderr when running tests.
