Phil Howard 517f8ae1cd global: Remove the STATIC macro. 
Reflect the changes proposed in micropython/micropython#13763.
 2024-06-03 13:44:23 +01:00
Phil Howard 47e3aed88f MicroPython: Switch to mp_obj_malloc_with_finaliser. 2024-06-03 11:40:29 +01:00
Skyler Mansfield b23a71b889 JPEGDEC: Backport width/height changes from pngdec. 
Open JPEG file or stream to read width/height before decode.
 2024-01-23 16:18:13 +00:00
Phil Howard d45daef654 MicroPython: Switch from MICROPY_EVENT_POLL_HOOK to mp_event_handle_nowait(). 
Note: Unsure if mp_event_handle_nowait() is the right answer in all cases,
but this seems to be what we want in our blocking loops.

Phil Howard 4b3e83f2ff JPEGDEC: Treat byte arrays as raw JPEG data for #435. 2023-09-29 09:18:55 +01:00
Mike Bell be943bd5a0 Fix build 2023-08-14 12:40:15 +01:00
Mike Bell f4b8bc9025 Fix Micropython build 2023-08-14 12:40:15 +01:00
Phil Howard b74b371d2b JPEGDEC: Don't pass filename through std::string. 
The result of GET_STR_DATA_LEN should be null terminated, so converting to a std::string and then using .c_str() is both redundant and need
s heap.
 2023-03-16 13:25:19 +00:00
Phil Howard bea90dfd60 JPEGDEC: Experimental 3bit/4bit palette no-dither. 2023-02-22 15:40:22 +00:00
Phil Howard 4928ceff8d Inky 7.3: Add pen type to JPEGDEC. 2023-02-20 12:29:59 +00:00
Phil Howard 9bd29e0ef2 JPEGDEC: Fix iWidthUsed skip not advancing pixel pointer. 2023-02-10 22:12:02 +00:00
Phil Howard 77a5edc83f MicroPython: Update to support new slots mp_obj_type_t. 
Follows the lead from: 662b9761b3

Update to support MP_DEFINE_CONST_OBJ_TYPE with backwards compatibility.
 2023-01-11 09:46:45 +00:00
Phil Howard 13414b5037 JPEGDEC: Clip drawing to iWidthUsed. 
Corrects clipping width using new iWidthUsed value, noticable particularly on smaller jpegs and those that aren't a multiple of the MCU sized.

Fixes #573
 2022-12-14 18:42:03 +00:00
Phil Howard 241e725464 JPEGDEC: Sync with upstream. 
Adds setUserPointer and pDraw->pUser which we now use to store a pointer to the PicoGraphics instance.
 2022-12-13 14:21:57 +00:00
Phil Howard e0a1627fba JPEGDEC/PicoGraphics: Add support for RGB888 target. 
Fixes https://github.com/pimoroni/pimoroni-pico/issues/573
 2022-12-13 14:03:30 +00:00
Phil Howard fddac54f86 JPEGDEC: Add option to disable dither on RGB332. 2022-08-11 11:46:45 +01:00
jon 50c7bd69ee Added missing switch case for new RGB888 pen type 2022-07-26 05:34:23 +01:00
Phil Howard 6c1556a429 PicoGraphics: 1bit/1bitY dither all drawing operations. 
Note: Pen now ranges from 0 (black) to 15 (white). Values between will be dithered ala Badger 2040.
 2022-07-06 11:32:56 +01:00
Phil Howard 12866a0b7b PicoGraphics/JPEGDEC: Use PicoGraphics dither. 2022-07-06 10:56:56 +01:00
Phil Howard cb5f8308a0 PicoGraphics/UC8159: 3bit bitplane pen mode. 
Add a 3bit pen mode to save 1/4th the RAM needed for the 600x448 Inky Frame.
 2022-06-30 15:25:02 +01:00
Phil Howard 7dbec2add6 JPEGDEC: Stream from filesystem. 
Avoid loading jpeg files into RAM and stream from the filesystem to handle larger files gracefully.
 2022-06-24 11:03:29 +01:00
Phil Howard e3f98d56cf PicoGraphics: UC8151 Support for Inky Pack. 2022-06-23 15:48:45 +01:00
jon 360bf4310c SH1107: Add driver and example. 
Add 1bit pen mode to PicoGraphics.

TODO:

* Rotation support
* Sizes other than 128x128 support

Phil Howard 31ade6af72 JPEGDEC: Open just before decode to avoid seek overrun. 2022-06-14 15:38:25 +01:00
Phil Howard 27d571b473 PicoGraphics: Tidy up dithering. 2022-06-14 15:06:44 +01:00
Phil Howard 6a3ba0d421 MicroPython: Shim MP_REGISTER_MODULE for >1.18 compat. 
MicroPython has changed MP_REGISTER_MODULE to use only *two* args and now runs the preprocessing stage on files before running makemoduledefs.py.

This change avoids the build exploding, since the new regex matches the last two args as a single argument and generates a malformed module defs include.

The pattern here exploits the fact that 1.18 and below do not preprocess files, so *both* MP_REGISTER_MODULE lines are included in the source, but *only* the three arg version is matched by regex.

In >1.18 the files will be processed and the three arg version removed before makemoduledefs.py processes it.

Phil Howard 2419f0ef45 PicoGraphics/JPEGDEC: RGB332 per channel fast dither. 2022-06-13 20:12:03 +01:00
Phil Howard 602d1b41dd PicoGraphics: Attempt at dither and scanline interrupts. 
Currently both unused and both very slow.

Dither may only be feasible for <=8 colour displays.

JPEGDEC will dither to 4-bit greyscale quite happily.
