MVLSB is deprecated but kept for backwards compatibility, for the time being. This patch also updates the associated docs and tests. extmod/modframebuf: Add support for monochrome horizontal format. 2017-03-20T05:21:47+00:00 Peter Hinch peter@hinch.me.uk 2017-02-06T10:59:44+00:00 urn:sha1:231cfc84a7cae31f93208c334fc33b08278040eb MHLSB and MHMSB formats are added to the framebuf module, which have 8 adjacent horizontal pixels represented in a single byte. extmod/modframebuf: Add GS4_HMSB format. 2017-01-25T12:19:28+00:00 Oleg Korsak kamikaze.is.waiting.you@gmail.com 2017-01-01T02:24:56+00:00 urn:sha1:fd99690f1859a46aee690355170ad13eed9f0122 extmod/modframebuf: Clip pixels drawn by line method. 2017-01-23T03:35:00+00:00 Damien George damien.p.george@gmail.com 2017-01-23T03:35:00+00:00 urn:sha1:e2d13d934a19651bb7c06c0212a1b875d8b9be1b extmod/modframebuf: optimize fill_rect subroutine call 2017-01-08T18:16:17+00:00 Oleg Korsak kamikaze.is.waiting.you@gmail.com 2017-01-07T20:03:51+00:00 urn:sha1:e45035db5c297190eee18cefa3b91b36b9f0e32b extmod/modframebuf: Store underlying buffer object to prevent GC free. 2016-12-09T01:58:45+00:00 Damien George damien.p.george@gmail.com 2016-12-09T01:58:45+00:00 urn:sha1:adf3cb50818636fdfb75e1a6a71b596565dcc90e extmod/modframebuf: Make framebuf implement the buffer protocol. 2016-12-08T04:17:47+00:00 Damien George damien.p.george@gmail.com 2016-12-08T04:17:47+00:00 urn:sha1:898d4c1217e69497c67ca2ddb66641406a03700b 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+00:00 Damien George damien.p.george@gmail.com 2016-12-05T00:52:51+00:00 urn: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+00:00 Damien George damien.p.george@gmail.com 2016-12-01T05:51:31+00:00 urn: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.
