So that one can easily access the underlying data of the frame buffer, eg
to write the data out to a display.
extmod/modframebuf: Add hline, vline, rect and line methods.2016-12-05T00:52:51+00:00Damien Georgedamien.p.george@gmail.com2016-12-05T00:52:51+00:00urn:sha1:374ed317c587dfc5ffcd9bdbe21aaa39d81c246b
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.
extmod/modframebuf: Optimise fill and fill_rect methods.2016-12-01T05:51:31+00:00Damien Georgedamien.p.george@gmail.com2016-12-01T05:51:31+00:00urn:sha1:a081b49d55ef409d612666d79a97e79259c8adba
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.
extmod/modframebuf: Add back legacy FrameBuffer1 "class".2016-12-01T05:43:25+00:00Damien Georgedamien.p.george@gmail.com2016-12-01T04:51:16+00:00urn:sha1:81e171b7bb38cff377ca389cd6fb179aea325998
For backwards compatibility. It simple creates a frame buffer with the
MVLSB format.
extmod/modframebuf: Make FrameBuffer handle 16bit depth.2016-12-01T05:43:25+00:00Radomir Dopieralskiopenstack@sheep.art.pl2016-08-28T15:44:36+00:00urn:sha1:225e22b2877c7731b7428db0e28d3ad7e6751e35
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.
all: Remove 'name' member from mp_obj_module_t struct.2016-09-21T14:23:16+00:00Damien Georgedamien.p.george@gmail.com2016-09-21T00:52:53+00:00urn:sha1:93c4a6a3f70e389b466fbc7a4f1ad2e1df87c93f
One can instead lookup __name__ in the modules dict to get the value.
extmod/framebuf: Add the xstep!=0 case to scroll() method.2016-09-05T02:06:56+00:00Radomir Dopieralskiopenstack@sheep.art.pl2016-09-02T14:15:37+00:00urn:sha1:778729c5977633978aef2ec302472505973a657e
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.
extmod/modframebuf: Include font from stmhal directory explicitly.2016-09-04T06:39:28+00:00Damien Georgedamien.p.george@gmail.com2016-09-04T06:39:28+00:00urn:sha1:47899a1ab8756c3850bb275f3756544da0e7b050
So that users of framebuf don't need to have stmhal directory in their
path. (Eventually the font can be moved elsewhere.)
extmod/modframebuf: Fix fill and scroll when height not divisible by 8.2016-09-02T13:58:34+00:00Radomir Dopieralskiopenstack@sheep.art.pl2016-08-28T17:13:32+00:00urn:sha1:41ec22632da8f61ca5c841e13206258048d1be5b
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.
