2017-01-23extmod/modframebuf: Clip pixels drawn by line method.Damien George

2016-12-09extmod/modframebuf: Store underlying buffer object to prevent GC free.Damien George
2016-12-08extmod/modframebuf: Make framebuf implement the buffer protocol.Damien George
So that one can easily access the underlying data of the frame buffer, eg to write the data out to a display.
2016-12-05extmod/modframebuf: Add hline, vline, rect and line methods.Damien George
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.
2016-12-01extmod/modframebuf: Optimise fill and fill_rect methods.Damien George
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.
2016-12-01extmod/modframebuf: Add back legacy FrameBuffer1 "class".Damien George
For backwards compatibility. It simple creates a frame buffer with the MVLSB format.
2016-12-01extmod/modframebuf: Make FrameBuffer handle 16bit depth.Radomir Dopieralski
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.
2016-09-22all: Remove 'name' member from mp_obj_module_t struct.Damien George
One can instead lookup __name__ in the modules dict to get the value.
2016-09-05extmod/framebuf: Add the xstep!=0 case to scroll() method.Radomir Dopieralski
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.
2016-09-04extmod/modframebuf: Include font from stmhal directory explicitly.Damien George
So that users of framebuf don't need to have stmhal directory in their path. (Eventually the font can be moved elsewhere.)
2016-09-02extmod/modframebuf: Fix fill and scroll when height not divisible by 8.Radomir Dopieralski
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.
2016-08-27extmod/modframebuf: Fix pixel accessor to return a 1-bit result.Damien George
2016-04-12extmod: Add initial framebuf module.Damien George
