821b59d439 stm32/timer: Use enum for indexing keyword arg in pyb_timer_init_helper. 2018-07-17 13:22:42 +10:00

c3c914f4dd esp8266,esp32: Implement high-res timers using new tick_hz argument.
machine.Timer now takes a new argument in its constructor (or init method):
tick_hz which specified the units for the period argument.  The period of
the timer in seconds is: period/tick_hz.

For backwards compatibility tick_hz defaults to 1000.  If the user wants to
specify the period (numerator) in microseconds then tick_hz can be set to
1000000.  The user can also specify a period of an arbitrary number of
cycles of an arbitrary frequency using these two arguments.

An additional freq argument has been added to allow frequencies to be
specified directly in Hertz.  This supports floating point values when
available.

components/esp32/test/test_tsens.c.  Temperature doesn't represent any
particular unit, isn't calibrated and will vary from device to device.

e94d644a81 py/runtime: Use mp_obj_new_int_from_ll when return int is not small.
There's no need to call mp_obj_new_int() which will just fail the check for
small int and call mp_obj_new_int_from_ll() anyway.

Thanks to @Jongy for prompting this change.

2a3979bcb3 stm32/fatfs_port: Fix bug when MICROPY_HW_ENABLE_RTC not enabled.
Prior to this patch, get_fattime() was calling a HAL RTC function with the
HW instance pointer as null because rtc_init_start() was never called.

Also marked it as a weak function, to allow a board to override it.

e2e22e3d7e py/objgenerator: Implement __name__ with normal fun attr accessor code.
With the recent change b488a4a848, a
generating function now has the same layout in memory as a normal bytecode
function, and so can reuse the latter's attribute accessor code to
implement __name__.

ee40d1704f mpy-cross: Make build independent of extmod directory.
mpy-cross doesn't depend on any code in the extmod directory so completely
exclude it from the build (extmod may still be scanned for qstrs but that
is controlled by py/py.mk).  This speeds up the build a little, and
improves abstraction of this component.

Also, make -I$(BUILD) take precedence over -I$(TOP) in case there are stray
files in the root directory that would be picked up.

4cd853fbd2 py/objmodule: Make mp_obj_module_get_globals an inline function.
Because this function is simple it saves code size to have it inlined.
Being an auxiliary helper function (and only used in the py/ core) the
argument should always be an mp_obj_module_t*, so there's no need for the
assert (and having it would require including assert.h in obj.h).

d9cdb880ff py/objdict: Make mp_obj_dict_get_map an inline function.
It's a very simple function and saves code, and improves efficiency, by
being inline.  Note that this is an auxiliary helper function and so
doesn't need mp_check_self -- that's used for functions that can be
accessed directly from Python code (eg from a method table).

a6ea6b08bc py: Simplify some cases of accessing the map of module and type dict.
mp_obj_module_get_globals() returns a mp_obj_dict_t*, and type->locals_dict
is a mp_obj_dict_t*, so access the map entry of the dict directly instead
of needing to cast this mp_obj_dict_t* up to an object and then calling the
mp_obj_dict_get_map() helper function.

106e594580 windows: Make printing of debugging info work out of the box.
Printing debugging info by defining MICROPY_DEBUG_VERBOSE expects
a definition of the DEBUG_printf function which is readily available
in printf.c so include that file in the build. Before this patch
one would have to manually provide such definition which is tedious.

For the msvc port disable MICROPY_USE_INTERNAL_PRINTF though: the
linker provides no (easy) way to replace printf with the custom
version as defined in printf.c.

8ad30fa433 lib/utils/printf: Make DEBUG_printf implementation more accessible.
The definition of DEBUG_printf doesn't depend on
MICROPY_USE_INTERNAL_PRINTF so move it out of that preprocessor
block and compile it conditionally just depending on the
MICROPY_DEBUG_PRINTERS macro. This allows a port to use DEBUG_printf
while providing it's own printf definition.

1751f5ac7b drivers/sdcard: Do not release CS during the middle of read operations.
It seems that some cards do not tolerate releasing the card (by setting CS
high) after issuing CMD17 (and 18) and raising it again before reading
data. Somehow this causes the 0xfe data start marker not being read and
SDCard.readinto() is spinning forever (or until this byte is in the data).

This seems to fix weird behviour of SDCard.readblocks() returning different
data, also solved hanging os.mount() for my case with a 16GB Infineon card.

This stackexchange answer gives more context:

14ab81e87a esp32: Reduce latency for handling of scheduled Python callbacks.
Prior to this patch there was a large latency for executing scheduled
callbacks when when Python code is sleeping: at the heart of the
implementation of sleep_ms() is a call to vTaskDelay(1), which always
sleeps for one 100Hz tick, before performing another call to
MICROPY_EVENT_POLL_HOOK.

This patch fixes this issue by using FreeRTOS Task Notifications to signal
the main thread that a new callback is pending.

bccf9d3dcf esp8266: Let machine.WDT trigger the software WDT if obj is not fed.
This patch allows scripts to have more control over the software WDT.  If
an instance of machine.WDT is created then the underlying OS is prevented
from feeding the software WDT, and it is up to the user script to feed it
instead via WDT.feed().  The timeout for this WDT is currently fixed and
will be between 1.6 and 3.2 seconds.

b6e5f82ba5 esp8266/modesp: Run ets_loop_iter before/after doing flash erase/write.
A flash erase/write takes a while and during that time tasks may be
scheduled via an IRQ.  To prevent overflow of the task queue (and loss of
tasks) call ets_loop_iter() before and after slow flash operations.

Note: if a task is posted to a full queue while a flash operation is in
progress then this leads to a fault when trying to print out the error
message that the queue is full.  This patch doesn't try to fix this
particular issue, it just prevents it from happening in the first place.

b488a4a848 py/objgenerator: Eliminate need for mp_obj_gen_wrap wrapper instances.
For generating functions there is no need to wrap the bytecode function in
a generator wrapper instance.  Instead the type of the bytecode function
can be changed to mp_type_gen_wrap.  This reduces code size and saves a
block of GC heap RAM for each generator.

d800ed1877 esp8266/esp8266_common.ld: Put mp_keyboard_interrupt in iRAM.
This function may be called from a UART IRQ, which may interrupt the system
when it is erasing/reading/writing flash.  In such a case all code
executing from the IRQ must be in iRAM (because the SPI flash is busy), so
put mp_keyboard_interrupt in iRAM so ctrl-C can be caught during flash
access.

This patch also takes get_fattime out of iRAM and puts it in iROM to make
space for mp_keyboard_interrupt.  There's no real need to have get_fattime
in iRAM because it calls other functions in iROM.

Fixes issue #3897.

d8dc918deb py/compile: Handle return/break/continue correctly in async with.
Before this patch the context manager's __aexit__() method would not be
executed if a return/break/continue statement was used to exit an async
with block.  async with now has the same semantics as normal with.

The fix here applies purely to the compiler, and does not modify the
runtime at all. It might (eventually) be better to define new bytecode(s)
to handle async with (and maybe other async constructs) in a cleaner, more
efficient way.

One minor drawback with addressing this issue purely in the compiler is
that it wasn't possible to get 100% CPython semantics.  The thing that is
different here to CPython is that the __aexit__ method is not looked up in
the context manager until it is needed, which is after the body of the
async with statement has executed.  So if a context manager doesn't have
__aexit__ then CPython raises an exception before the async with is
executed, whereas uPy will raise it after it is executed.  Note that
__aenter__ is looked up at the beginning in uPy because it needs to be
called straightaway, so if the context manager isn't a context manager then
it'll still raise an exception at the same location as CPython.  The only
difference is if the context manager has the __aenter__ method but not the
__aexit__ method, then in that case uPy has different behaviour.  But this
is a very minor, and acceptable, difference.
