Paul Sokolovsky eac22e29a5 all: Consistently update signatures of .make_new and .call methods.
Otherwise, they serve reoccurring source of copy-paste mistakes and
breaking nanbox build.

Damien George 304cfda8c4 py/stream: Move ad-hoc ioctl constants to stream.h and rename them.
The constants MP_IOCTL_POLL_xxx, which were stmhal-specific, are moved
from stmhal/pybioctl.h (now deleted) to py/stream.h.  And they are renamed
to MP_STREAM_POLL_xxx to be consistent with other such constants.

All uses of these constants have been updated.

Krzysztof Blazewicz 7604de3fc2 stmhal/can: clear FIFO flags in IRQ handler
HAL Driver before v1.4.2 had a bug which caused clearing all pending
flags in MSR, TSR, RF0R and RF1R instead of only the requested one.

This is why micropython got away without explicitly clearing flags
in IRQ handler.

Paul Sokolovsky 07209f8592 all: Rename mp_obj_type_t::stream_p to protocol.
It's now used for more than just stream protocol (e.g. pin protocol), so
don't use false names.

Damien George 5ab98d5c41 stmhal: Convert to use internal errno symbols; enable uerrno module. 2016-05-10 23:30:39 +01:00
Henrik Sölver c4587e2426 stmhal/can: Allow to get existing CAN obj if constructed without args.
Initialisation of CAN objects should now behave as other peripheral
objects.

Fixes issue #2001.

Damien George 5b3f0b7f39 py: Change first arg of type.make_new from mp_obj_t to mp_obj_type_t*.
The first argument to the type.make_new method is naturally a uPy type,
and all uses of this argument cast it directly to a pointer to a type
structure.  So it makes sense to just have it a pointer to a type from
the very beginning (and a const pointer at that).  This patch makes
such a change, and removes all unnecessary casting to/from mp_obj_t.

Dave Curtis 32b3549cce stmhal: Add symbolic #defines for interrupt levels in irq.h. 2015-11-01 23:23:39 +00:00
Damien George 731f359292 all: Add py/mphal.h and use it in all ports.
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.

Damien George 1775b65e07 stmhal: Remove PYBVxx defines and use config vars for UART/CAN names.
Now all stmhal-based boards can name their peripherals (if they want) to
any string.

Damien George 7f9d1d6ab9 py: Overhaul and simplify printf/pfenv mechanism.
Previous to this patch the printing mechanism was a bit of a tangled
mess.  This patch attempts to consolidate printing into one interface.

All (non-debug) printing now uses the mp_print* family of functions,
mainly mp_printf.  All these functions take an mp_print_t structure as
their first argument, and this structure defines the printing backend
through the "print_strn" function of said structure.

Printing from the uPy core can reach the platform-defined print code via
two paths: either through mp_sys_stdout_obj (defined pert port) in
conjunction with mp_stream_write; or through the mp_plat_print structure
which uses the MP_PLAT_PRINT_STRN macro to define how string are printed
on the platform.  The former is only used when MICROPY_PY_IO is defined.

With this new scheme printing is generally more efficient (less layers
to go through, less arguments to pass), and, given an mp_print_t*
structure, one can call mp_print_str for efficiency instead of
mp_printf("%s", ...).  Code size is also reduced by around 200 bytes on
Thumb2 archs.

Damien George 05005f679e py: Remove mp_obj_str_builder and use vstr instead.
With this patch str/bytes construction is streamlined.  Always use a
vstr to build a str/bytes object.  If the size is known beforehand then
use vstr_init_len to allocate only required memory.  Otherwise use
vstr_init and the vstr will grow as needed.  Then use
mp_obj_new_str_from_vstr to create a str/bytes object using the vstr
memory.

Saves code ROM: 68 bytes on stmhal, 108 bytes on bare-arm, and 336 bytes
on unix x64.

Paul Sokolovsky f4a6a577ab stream: Convert .ioctl() to take fixed number of args.
This is more efficient, as allows to use register calling convention.
If needed, a structure pointer can be passed as argument to pass more
data.
