Without this, spi.read(1, 0xff) would use 16 clock cycles,
first to send 0xff and then to receive one byte, as visible
with a logic analyzer.

This updates the print function for machine.Pin to
print out the new constants from the Hardware API defintion
rather than the legacy definitions.

It has reliability issues and sometimes fails on Travis (reason currently
unknown).

Disable by default, enable in unix port.

In current state `mp_get_stream_raise` assumes that `self_in` is an object
and always performs a pointer derefence which may cause a segfault.
This function shall throw an exception whenever `self_in` does not implement
a stream protocol, that includes qstr's and numbers.
fixes #2331

In `btree_seq()`, when `__bt_seq()` gets called with invalid
`flags` argument it will return `RET_ERROR` and it won't
initialize `val`. If field `data` of uninitialized `val`
is passed to `mp_obj_new_bytes()` it causes a segfault.

TIM3 is no longer special, or at least does not have special IRQ settings.
|
|
It turns out that TIM1 and TIM8 have their own Capture/Compare
interrupt vector. For all of the other timers, the capture/compare
interrupt vector is the same as the update vector.
So we need to add handlers for these vectors and enable them
when using capture/compare callbacks.
During testing of this, I also found that passing a channel callback
into the channel constructor would not enable interrupts properly.
I tested using:
```
>>> pyb.Timer(1, freq=4).channel(1, pyb.Timer.OC_TOGGLE, callback=lambda t: print('.', end=''))
```
I tested the above with channels 1, 4, and 8

Disabling it was an omission from early development stages.

This module uses ESP8266's SPI hardware, which allows much higher
speeds. It uses a library from
https://github.com/MetalPhreak/ESP8266_SPI_Driver

Consistently use stdint types. Fixes stmhal build.

It has reliability issues that need to be worked out.

Fixes for pedantic compiler warnings.

New API supporting stream decompression.
|
|
These additional special methods are enabled on most ports so we can test
them in this test.
|
|
The qemu-arm port is for testing, so should have features enabled.

This type was used only for the typedef of mp_obj_t, which is now defined
by the object representation. So we can now remove this unused typedef,
to simplify the mpconfigport.h file.
|
|
The machine_ptr_t type is long obsolete as the type of mp_obj_t is now
defined by the object representation, ie by MICROPY_OBJ_REPR. So just use
void* explicitly for the typedef of mp_obj_t.
If a port wants to use something different then they should define a new
object representation.

This patch does further refactoring using the new mp_raise_TypeError
and mp_raise_ValueError functions.
|
|
|
|
Only tuple, namedtuple and attrtuple use the tuple_cmp_helper function,
and they all have getiter=mp_obj_tuple_getiter, so the check here is only
to ensure that the self object is consistent. Hence use mp_check_self.
|
|
|
|
To use the actual current name.
|
|
Checks for number of args removes where guaranteed by function descriptor,
self checking is replaced with mp_check_self(). In few cases, exception
is raised instead of assert.
|
|
|
|
Indended to replace raw asserts in bunch of files. Expands to empty
if MICROPY_BUILTIN_METHOD_CHECK_SELF_ARG is defined, otehrwise by
default still to assert, though a particular port may define it to
something else.
|
|
Introduce mp_raise_msg(), mp_raise_ValueError(), mp_raise_TypeError()
instead of previous pattern nlr_raise(mp_obj_new_exception_msg(...)).
Save few bytes on each call, which are many.

Fixing Issue #2243. Main problems were:
- HAL_ADC_GetState(adcHandle) may return other bits set (not only
HAL_ADC_STATE_EOC_REG) when called - so I AND-ed it out as proposed by
mattbrejza in Issue #2243.
- ADC Pin has to be configured as GPIO_MODE_ANALOG_ADC_CONTROL not only
GPIO_MODE_ANALOG.
- Resolved ADC resolution L4 specific (Use L4 define ADC_RESOLUTION_12B).
- Changed setting of Init.EOCSelection toADC_EOC_SINGLE_CONV for L4.
- Added call to ADC_MultiModeTypeDef as this is done on a STM32Cube
generated project too.
- Clean up: Configuration of ADC is done only in ONE function not the same
is done in two functions.
Test is done on PA5 pin of STM32L4Discovery-Kit which is connected to the
DOWN button.
Thanks to mattbrejza for discovering the bug.

This patch introduces proper ADC Pin definitions in stm32l476_af.csv.

Fixes build errors such as
"../lib/utils/printf.c:43:5: error: expected parameter declarator"
|
|
It used a standard BootROM programming algo and may be useful as a
fallback.
|
|
The tool now generates code for freezing floats in obj-repr A, B or C,
with the specific representation detected at compile time using macros.
|
|
|
|
Pin(16) now works as an input.
