2021-01-26rgbmatrix: Eliminate some duplicated height-calculating codeJeff Epler
This was hard to write, so let's have it written in 2 places instead of 4.
2021-01-26RGBMatrix: Additional tile tweaksJeff Epler
* Introduce explicit serpentine: bool argument instead of using negative numbers (thanks, ghost of @tannewt sitting on one shoulder) * Fix several calculations of height Testing performed (matrixportal): * set up a serpentine 64x64 virtual display with 2 64x32 tiles * tried all 4 rotations * looked at output of REPL

EVE: change fixed-point integer arguments to floating point
2021-01-25Merge pull request #3936 from gamblor21/busdevice_fixesScott Shawcroft
Changing adafruit_bus_device to duck typing
2021-01-22Change from fixed-point integer arguments to floating point in EVE API functionsJames Bowman
Changed calls: PointSize(), LineWidth(), VertexTranslateX() and VertexTranslateY() Units for all the above are now pixels, not fixed-point integers. This matches OpenGL. Docstrings updated accordingly

2021-01-20Add initial RP2040 supportScott Shawcroft
The RP2040 is new microcontroller from Raspberry Pi that features two Cortex M0s and eight PIO state machines that are good for crunching lots of data. It has 264k RAM and a built in UF2 bootloader too. Datasheet: https://pico.raspberrypi.org/files/rp2040_datasheet.pdf

2020-12-17OnDiskBitmap: Correct handling of "0 color palette" imagesJeff Epler
Microsoft documentation says: > If biCompression equals BI_RGB and the bitmap uses 8 bpp or less, the bitmap has a color table immediatelly following the BITMAPINFOHEADER structure. The color table consists of an array of RGBQUAD values. The size of the array is given by the biClrUsed member. If biClrUsed is zero, the array contains the maximum number of colors for the given bitdepth; that is, 2^biBitCount colors. Formerly, we treated 0 colors as "no image palette" during construction, but then during common_hal_displayio_ondiskbitmap_get_pixel indexed into the palette anyway. This could have unpredictable results. On a pygamer, it gave an image that was blue and black. On magtag, it gave a crash.
2020-12-16displayio: ColorConverter: fix logic errors about transparent pixelsJeff Epler
The transparent_color field was never initialized. I _think_ this means its value was always set to 0, or the blackest of blacks. Instead, initialize it to the sentinel value, newly given the name NO_TRANSPARENT_COLOR. This exposed a second problem: The test for whether there was an existing transparent color was wrong (backwards). I am guessing that this was not found due to the first bug; since the converter had a transparent color, the correct test would have led to always getting the error "Only one color can be transparent at a time". Closes #3723

2020-11-28Fix align32_size().Christian Walther
It not only caused crashes with requests larger than 64K (can happen with RGBMatrix), but also generated a lot longer code than necessary.
2020-11-28Use movable allocation system for RGBMatrix allocations.Christian Walther
Hybrid allocation is now part of the infrastructure. Moving memory contents would not be necessary because displayio can recreate them, but does not hurt.
2020-11-28Use movable allocation system for Sharp display framebuffer.Christian Walther
Hybrid allocation is now part of the infrastructure. Moving memory contents would not be necessary because displayio can recreate them, but does not hurt.
2020-11-28Add movable allocation system.Christian Walther
This allows calls to `allocate_memory()` while the VM is running, it will then allocate from the GC heap (unless there is a suitable hole among the supervisor allocations), and when the VM exits and the GC heap is freed, the allocation will be moved to the bottom of the former GC heap and transformed into a proper supervisor allocation. Existing movable allocations will also be moved to defragment the supervisor heap and ensure that the next VM run gets as much memory as possible for the GC heap. By itself this breaks terminalio because it violates the assumption that supervisor_display_move_memory() still has access to an undisturbed heap to copy the tilegrid from. It will work in many cases, but if you're unlucky you will get garbled terminal contents after exiting from the vm run that created the display. This will be fixed in the following commit, which is separate to simplify review.

* Initialize the EPaper display on the MagTag at start. * Tweak the display send to take a const buffer. * Correct Luma math * Multiply the blue component, not add. * Add all of the components together before dividing. This reduces the impact of truncated division.
