Phil Howard 973fade9fd MicroPython: Fix errors reporting an errno. 2025-03-28 10:31:01 +00:00
Phil Howard 3d68cf0010 MicroPython: Add MP_ERROR_TEXT() around errors. 
This is required for MicroPython error text compression which is
going to be enabled by default for RP2 builds.

We have a lot of error messages, so the potential flash gain here
is worth the effort of making this work.

Phil Howard fdfb28ebb8 Unicorns: Disable Hershey fonts to reclaim some bytes. 2025-03-28 10:31:01 +00:00
Phil Howard a25b27aca8 PicoVector: Improve transform handling. 
* Store a reference to transform, so `set_transform(Transform())` is not GC'd until it is replaced
* Transformations return the transform, allowing chaining: `transform.rotate().scale().translate()`
* A new `get_transform` method for getting the currently set transform.

Phil Howard b3d7bd497d Hershey Fonts: ifdef guard hershey features for eventual deprecation. 
Hershey fonts have all but been replaced by PicoVector's "Alright Fonts"
implementation and in many case we need this flash back!

Phil Howard 7fee95d668 PNG/JPEGDEC: Remove finalizer. 
Remove the finalizer from PNGDEC and JPEGDEC, since it was both redundant
and actively harmful.

The finalizer was just calling "close" which is unecessary since the file
is closed automatically after opening/rendering and not left open.

If a file did not exist and "open_file" bailed with ENOENT then it would
be left in an unknown state, and the finalizer calling "close" would
cause a hardlock.

Phil Howard 14388e0984 CI: Bump MicroPython to v1.24.1. 2025-03-28 10:31:01 +00:00
Phil Howard 5c19c6ab6a PicoVector: AF: Support for 16bit point count. 
Somewhere in the conversion from C++ to C we lost support for 16-bit point counts.

Raise the internal point count to 16-bit, and check for a flag in the font.

If the flag is set, treat the point count as 16-bits, otherwise fallback to 8 for back compatibility.

Phil Howard 4a3f0a435d PicoVector: Fix fonts not rendering with no transform set. 2025-03-28 10:31:01 +00:00

Phil Howard 79844c6eaa PicoVector: Fix bug in polygon iterator. 
list(Polygon) should return a list of points, but crashed with non-empty polygons.

We were advancing to the next path and then retriving an invalid point count for building the tuple.

Save the point count before advancing to the next path.

Phil Howard ba767b5217 PicoVector: Initialise pp_transform(). 
For some reason this was unset causing drawing to fail.

Reset it to a known good state in the constructor.

Fix spurious point in top-left corner causing a broken triangular
rectangle when any permutation of corners other than the bottom-left
is rounded.

Phil Howard cb6bf89a33 Hub75: Performance improvements and stacked mode. 
Inline and simplify the pixel flip for a 13.2ms -> 3.8ms speedup at 128x128 on RP2350 stock.

Drop RGB565 mode.

Add the ability to stack some panels, eg: 2x128x64 in a 128x127 configuration.

Phil Howard 8b32174fc9 PicoVector: Avoid MicroPython GC. 
Since we're not using tracked allocation, any memory we don't explicitly
hold a reference to will be assumed unused by MicroPython's GC.

Pass up the pp_nodes and pp_node_counts points (hackily) to fix this.

Phil Howard 8f87e1c75f PicoVector: Remove * 4 from pp_nodes lookup. 2025-03-28 10:31:01 +00:00

Phil Howard 074570f99c PicoVector: Revert the tile buffer to be fixed. 
Ensure that MicroPython doesn't ever place the tile buffer into PSRAM
and trash performance.

Phil Howard 24eee10895 PicoGraphics: Non-blocking Inky update for #936. 2025-03-28 10:31:01 +00:00
Phil Howard 64136cdb83 Plasma: Add support for GPIOs >=32. 
For both APA102 and WS2812 the pins used on the same PIO must be in the same range.
The GPIO base offset applies to the whole PIO and not individual state machines.

This means that for APA102 both data and clock must be in the same pin range,
ie: either 16-48 inclusive or 0-31 inclusive.
