Also known as L2CAP "connection oriented channels". This provides a
socket-like data transfer mechanism for BLE.
Currently only implemented for NimBLE on STM32 / Unix.

This requires that the event handlers are called from non-interrupt context
(i.e. the MicroPython scheduler).
This will allow the BLE stack (e.g. NimBLE) to run from the scheduler
rather than an IRQ like PENDSV, and therefore be able to invoke Python
callbacks directly/synchronously. This allows writing Python BLE handlers
for events that require immediate response such as _IRQ_READ_REQUEST (which
was previous a hard IRQ) and future events relating to pairing/bonding.

So that g++ is not needed to build a non-coverage unix variant.

Support building .cpp files and linking them into the micropython
executable in a way similar to how it is done for .c files. The main
incentive here is to enable user C modules to use C++ files (which are put
in SRC_MOD_CXX by py.mk) since the core itself does not utilize C++.
However, to verify build functionality a unix overage test is added. The
esp32 port already has CXXFLAGS so just add the user modules' flags to it.
For the unix port use a copy of the CFLAGS but strip the ones which are not
usable for C++.

This commit adds support for using Bluetooth on the unix port via a H4
serial interface (distinct from a USB dongle), with both BTstack and NimBLE
Bluetooth stacks.
Note that MICROPY_PY_BLUETOOTH is now disabled for the coverage variant.
Prior to this commit Bluetooth was anyway not being built on Travis because
libusb was not detected. But now that bluetooth works in H4 mode it will
be built, and will lead to a large decrease in coverage because Bluetooth
tests cannot be run on Travis.
|

|
|
Previously the interaction between the different layers of the Bluetooth
stack was different on each port and each stack. This commit defines
common interfaces between them and implements them for cyw43, btstack,
nimble, stm32, unix.
|
|
Changes are:
- The default manifest.py is moved to the variants directory (it's in
"boards" in other ports).
- The coverage variant now uses a custom manifest in its variant directory
to add frzmpy/frzstr.
- The frzmpy/frzstr tests are moved to variants/coverage/.

No functionality change is intended with this commit, it just consolidates
the separate implementations of GC helper code to the lib/utils/ directory
as a general set of helper functions useful for any port. This reduces
duplication of code, and makes it easier for future ports or embedders to
get the GC implementation correct.
Ports should now link against gchelper_native.c and either gchelper_m0.s or
gchelper_m3.s (currently only Cortex-M is supported but other architectures
can follow), or use the fallback gchelper_generic.c which will work on
x86/x64/ARM.
The gc_helper_get_sp function from gchelper_m3.s is not really GC related
and was only used by cc3200, so it has been moved to that port and renamed
to cortex_m3_get_sp.

But only when bluetooth is enabled, i.e. if building the dev or coverage
variants, and we have libusb available.
Update travis to match, i.e. specify the variant when doing
`make submodules`.
|
|
And MICROPY_PY_URANDOM_EXTRA_FUNCS is enabled on "dev" so tha the Bluetooth
examples all run.
|
|
This commit adds full support to the unix port for Bluetooth using the
common extmod/modbluetooth Python bindings. This uses the libusb HCI
transport, which supports many common USB BT adaptors.
|
|
Add -Wdouble-promotion and -Wfloat-conversion for most ports to ban out
implicit floating point conversions, and add extra Travis builds using
MICROPY_FLOAT_IMPL_FLOAT to uncover warnings which weren't found
previously. For the unix port -Wsign-comparison is added as well but only
there since only clang supports this but gcc doesn't.
|
|
This was fixed previously in 31fc81d3b8bb227109777eed02d0021e564fb523 but
regressed in 4af79e76943312bf71be395a71fa80ab39e7c2c2.
Fixes #5885.

Based on eg 1e6fd9f2b4072873f5d6846b19b2ef0ccc5e4e52, it's understood that
the intention for unix builds is that regular builds disable assert, but
the coverage build should set -O0 and enable asserts.
It looks like this didn't work (even before variants were introduced, eg at
v1.11) -- coverage always built with -Os and -DNDEBUG.
This commit makes it possible for variants to have finer-grained control
over COPT flags, and enables assert() and -O0 on coverage builds.
Other variants already match the defaults so they have been updated.
|
|
The implementation in extmod/vfs_posix_file.c is now equivalent to that in
ports/unix/file.c, so remove the latter and use the former instead.
|
|
|
|
The install target is current broken when PROG is used to override the
default executable name. This fixes it by removing the redundant TARGET
variable and uses PROG directly instead.
The install and uninstall targets are also moved to the common unix
Makefile so that all variants can be installed in the same way.
|
|
To eliminate confusion about what targets to use when building.
|
|
When CFLAGS_EXTRA/LDFLAGS_EXTRA (or anything) is set on the command line of
a make invocation then it will completely override any setting or appending
of these variables in the makefile(s). This means builds like the coverage
variant will have their mpconfigvariant.mk settings overridden. Fix this
by using CFLAGS/LDFLAGS exclusively in the makefile(s), reserving the
CFLAGS_EXTRA/LDFLAGS_EXTRA variables for external command-line use only.
|
|
Invoking "make" will still build the standard "micropython" executable, but
other variants are now build using, eg, "make VARIANT=minimal". This
follows how bare-metal ports specify a particular board, and allows running
any make target (eg clean, test) with any variant.
Convenience targets (eg "make coverage") are provided to retain the old
behaviour, at least for now.
See issue #3043.

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.
|
|
These classes are enabled via the config options MICROPY_VFS_LFS1 and
MICROPY_VFS_LFS2, which are disabled by default.
|

|
|
Removes symlinks in modules directory, all frozen code is now specified by
manifest.py.

|
|
For example, on Android, pthread functions are part of libc, so LIBPTHREAD
should be empty.
|
|
Avoids polluting the source tree, allows to build for different (sub)archs
without intermediate cleaning.

"coverage" build uses different BUILD directory comparing to the normal
build. Previously, any build picked up libaxtls.a from normal build's
directory, but that was fixed recently. So, for each build, we must
build axtls explicitly.
This fixes Travis build in particular.
|
|
|
|
|
|
This build sets CFLAGS_EXTRA itself, but preserve user's value as passed
on make command line/etc.
|
|
Unix naming is historical, before current conventions were established.
All other ports however have it as "modusocket.c", so rename for
consistency and to avoid confusion.
|
|
Also renames "stmhal" to "stm32" in documentation and everywhere else.
|
|
This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
