It's no longer needed because this macro is now processed after
preprocessing the source code via cpp (in the qstr extraction stage), which
means unused MP_REGISTER_MODULE's are filtered out by the preprocessor.

And add spaces after commas so it is consistently formatted.

This replaces occurences of
foo_t *foo = m_new_obj(foo_t);
foo->base.type = &foo_type;
with
foo_t *foo = mp_obj_malloc(foo_t, &foo_type);
Excludes any places where base is a sub-field or when new0/memset is used.

This achieves a substantial performance improvement when rendering glyphs
to color displays, the benefit increasing proportional to the number of
pixels in the glyph.
|
|
These args are already bounds checked and clipped, and using unsigned ints
can be more efficient. It also eliminates possible issues and compiler
warnings with shifting of signed integers.

This is run with uncrustify 0.70.1, and black 19.10b0.

So they can be built as dynamic native modules, as well as existing static
native modules.

This format is used in 2-color LED matrices and in e-ink displays like
SSD1606.

Header files that are considered internal to the py core and should not
normally be included directly are:
py/nlr.h - internal nlr configuration and declarations
py/bc0.h - contains bytecode macro definitions
py/runtime0.h - contains basic runtime enums
Instead, the top-level header files to include are one of:
py/obj.h - includes runtime0.h and defines everything to use the
mp_obj_t type
py/runtime.h - includes mpstate.h and hence nlr.h, obj.h, runtime0.h,
and defines everything to use the general runtime support functions
Additional, specific headers (eg py/objlist.h) can be included if needed.

Also renames "stmhal" to "stm32" in documentation and everywhere else.

Thanks to @kamikaze, aka Oleg Korsak, for the original idea and patch.

Since the stride is specified in pixels, in a 4-bit horizontal format it
has to always be even, otherwise the computation is wrong and we can
write outside of the buffer sometimes.
|

|
|
Happened with 32-bit gcc 4.8.4.
|
|
MONO_xxx is much easier to read if you're not familiar with the code.
MVLSB is deprecated but kept for backwards compatibility, for the time
being.
This patch also updates the associated docs and tests.
|
|
MHLSB and MHMSB formats are added to the framebuf module, which have 8
adjacent horizontal pixels represented in a single byte.
|
|
|
|
|
|
|
|
|
|
So that one can easily access the underlying data of the frame buffer, eg
to write the data out to a display.
|
|
These are basic drawing primitives. They work in a generic way on all
framebuf formats by calling the underlying setpixel or fill_rect C-level
primitives.
|
|
Fill is a very common operation (eg to clear the screen) and it is worth
optimising it, by providing a specialised fill_rect function for each
framebuffer format.
This patch improved the speed of fill by 10 times for a 16-bit display
with 160*128 pixels.
|
|
For backwards compatibility. It simple creates a frame buffer with the
MVLSB format.
|
|
Rename FrameBuffer1 into FrameBuffer and make it handle different bit
depths via a method table that has getpixel and setpixel. Currently
supported formats are MVLSB (monochrome, vertical, LSB) and RGB565.
Also add blit() and fill_rect() methods.
|
|
One can instead lookup __name__ in the modules dict to get the value.
|
|
Adds horizontal scrolling. Right now, I'm just leaving the margins
created by the scrolling as they were -- so they will repeat the
edge of the framebuf. This is fast, and the user can always fill
the margins themselves.
|
|
So that users of framebuf don't need to have stmhal directory in their
path. (Eventually the font can be moved elsewhere.)
|
|
There was a bug in `framebuf1_fill` function, that makes it leave a few
lines unfilled at the bottom if the height is not divisible by 8.
A similar bug is fixed in the scroll method.
