See issue #1814.

Update the help() implementations in the cc3200, stmhal and teensy
ports to use the pyhelp_print_obj function.

- add template rule that converts a specified source file into a qstring file
- add special rule for generating a central header that contains all
extracted/autogenerated strings - defined by QSTR_DEFS_COLLECTED
variable. Each platform appends a list of sources that may contain
qstrings into a new build variable: SRC_QSTR. Any autogenerated
prerequisities are should be appened to SRC_QSTR_AUTO_DEPS variable.
- remove most qstrings from py/qstrdefs, keep only qstrings that
contain special characters - these cannot be easily detected in the
sources without additional annotations
- remove most manual qstrdefs, use qstrdef autogen for: py, cc3200,
stmhal, teensy, unix, windows, pic16bit:
- remove all micropython generic qstrdefs except for the special strings that contain special characters (e.g. /,+,<,> etc.)
- remove all port specific qstrdefs except for special strings
- append sources for qstr generation in platform makefiles (SRC_QSTR)

The config variable MICROPY_MODULE_FROZEN is now made of two separate
parts: MICROPY_MODULE_FROZEN_STR and MICROPY_MODULE_FROZEN_MPY. This
allows to have none, either or both of frozen strings and frozen mpy
files (aka frozen bytecode).

tools/pydfu.py is now the recommended way of deploying a DFU file. Old
behaviour of dfu-util can be obtained by passing USE_PYDFU=0 when invoking
make.
The main README.md file has been updated to reflect this change.

TODO: Probably merge into vfs_fat_diskio.
|
|
|
|
|
|
Move definition of mp_builtin_open_obj to a separate module, then file.c
becomes more or less compartmentalized FatFs file class, which can be used
together with file class implementations for other (V)FSes.
|
|
|
|
This allows FROZEN_DIR=some-directory to be specified on the make
command line, which will then add all of the files contained within
the indicated frozen directory as frozen files in the image.
There is no change in flash/ram usage if not using the feature.
This is especially useful on smaller MCUs (like the 401) which only
has 64K flash file system.

|
Adds 924 bytes of code, but means that no more hacks and work-arounds are
needed due to large constants becoming negative.

This file contains various MicroPython-specific helper functions, so isn't
good fit for lib/libc/.
|
|
|

py/mphal.h contains declarations for generic mp_hal_XXX functions, such
as stdio and delay/ticks, which ports should provide definitions for. A
port will also provide mphalport.h with further HAL declarations.

Scenario: module1 depends on some common file from lib/, so specifies it
in its SRC_MOD, and the same situation with module2, then common file
from lib/ eventually ends up listed twice in $(OBJ), which leads to link
errors.
Make is equipped to deal with such situation easily, quoting the manual:
"The value of $^ omits duplicate prerequisites, while $+ retains them and
preserves their order." So, just use $^ consistently in all link targets.

Generally, ports should inherit INC from py.mk, append to it, not
overwrite it. TODO: Likely should do the same for other vars too.

This fix adds PIDs 9801 and 9802 to the pybcdc.inf file.
When in CDC only mode, it presents itself as a Communcations
device rather than as a composite device. Presenting as a
composite device with only the CDC interface seems to confuse
windows.
To test and make sure that the correct pybcdc.inf was being used,
I used USBDeview from http://www.nirsoft.net/utils/usb_devices_view.html
to uninstall any old pyboard drivers (Use Control-F and search
for pyboard). I found running USBDeview as administrator worked best.
Installing the driver in CDC+MSC mode first is recommended (since the
pybcdc.inf file in on the internal flash drive). Then when you switch
modes everything seems to work properly.
I used https://github.com/dhylands/upy-examples/blob/master/boot_switch.py
to easily switch the pyboard between the various USB modes for testing.

This needs to land afte #1407 lands, since #1407 is where
the CMSIS_MCU was defined.

|
This causes unnecessary constants to no longer be generated.
Some constants (like UART_BRR) are different between the F4 and F7

Thanks to Dave Hylands for the patch.

This is so that the DMA can be shared by multiple peripherals.

Each board now needs an mpconfigboard.mk file which defines AF_FILE and
LD_FILE.
Also moved stm32f405.ld to boards/ directory to keep things organised.

|
This can get PYBv1.0 stop current down to around 290uA.
|
|
This helps make files reusable across other ports.
|
|
|
|
|
|
The unused files are from the ST demos for different USB classes and are
not needed for the stmhal port.

Addresses issue #1081.
