2021-01-14update uzlib to v2.9.5Jeff Epler
uzlib isn't actually used in any firmwares, but is built into the "unix" port used for testing. The main benefit of the update is to fix problems encountered on Windows, as the old ref of uzlib had filenames with embedded colons; this has been fixed upstream. uzlib seems to have been reabsed since the version that we took; this doesn't really matter to us.

2020-11-10protomatter: Update to upstream tag 1.0.10Jeff Epler
Among other things this fixes a problem with blanking the display and Closes #3664.

this is compile-tested on stm32f405 feather matrixportal nrf52840 feather but not actually tested-tested.
2020-10-03Update protomatterJeff Epler
This brings in the following, and updates us to the 1.0.4 release tag: Submodule lib/protomatter 2a1ba8fa4..5f07ec618: > Bumping version for release > Merge pull request #21 from makermelissa/master > Merge pull request #20 from makermelissa/master > Merge pull request #18 from jepler/fix-cpy-3184 > Merge pull request #14 from hierophect/cpy-timer-allocator We previously had the _changes_ of jepler/fix-cpy-3184 and hierophect/cpy-timer-allocator but not their merge commits. The only other changes in protomatter were one formatting change in the core, plus several Arduino sketches. So this should make no practical difference for CPy.

2020-09-01rgbmatrix: recover gracefully from allocation errorsJeff Epler
e.g., allocating a 192x32x6bpp matrix would be enough to trigger this reliably on a Metro M4 Express using the "memory hogging" layout. Allocating 64x32x6bpp could trigger it, but somewhat unreliably. There are several things going on here: * we make the failing call with interrupts off * we were throwing an exception with interrupts off * protomatter failed badly in _PM_free when it was partially-initialized Incorporate the fix from protomatter, switch to a non-throwing malloc variant, and ensure that interrupts get turned back on. This decreases the quality of the MemoryError (it cannot report the size of the failed allocation) but allows CircuitPython to survive, rather than faulting.

2020-08-25pyexec: Handle a ctrl-c that comes in "very late"Jeff Epler
In relatively unusual circumstances, such as entering `l = 17 ** 17777` at the REPL, you could hit ctrl-c, but not get KeyboardInterrupt. This can lead to a condition where the display would stop updating (#2689).

2020-08-09Refactor utf-8 code, reduce impact on code sizeGeorge Waters
2020-08-09Fix repl support for unicodeGeorge Waters
Currently when a utf8 character that is bigger than 1 byte is typed in the repl, it isn't handled how it should be. If you try to move the cursor in any direction the text gets messed up. This fixes that.
2020-08-04libm: rem_pio2: Reduce size of static arrayJeff Epler
This array was of 32-bit values, but the entries were only ever in the 0-255 range. Convert to uint8_t. Testing performed: The result of the sum-of-sin was unchanged >>> import math; sum(math.sin(2.**i) for i in range(21)) 1.42069
2020-08-04libm: ef_rem_pio2.c: Save ROM-tables at the expense of speedJeff Epler
This function computes the remainder of a value `x` modulo pi/2, to high precision. It does this by dividing the flotaing point values into several ranges by magnitude, and applies successively slower but more accurate algorithms. The last two steps, one covering values up to around 2^7 * pi/2 (called "medium size") and a final one covering all possible float values, require big tables. By eliminating the "medium size" case, a table and some code are removed from the binary. This makes some cases take longer, but saves hundreds of bytes. It does _NOT_ affect the result, only the speed. ``` [desktop python] >>> sum(math.sin(2.**i) for i in range(21)) 1.4206898748939305 [trinket m0, before change to ef_rem_pio2.c] >>> sum(math.sin(2.**i) for i in range(21)) 1.42069 [trinket m0, after change to ef_rem_pio2.c] >>> sum(math.sin(2.**i) for i in range(21)) 1.42069 ```

2020-01-17Refine iMX RT memory layout and add three boardsScott Shawcroft
Introduces a way to place CircuitPython code and data into tightly coupled memory (TCM) which is accessible by the CPU in a single cycle. It also frees up room in the corresponding cache for intermittent data. Loading from external flash is slow! The data cache is also now enabled. Adds support for the iMX RT 1021 chip. Adds three new boards: * iMX RT 1020 EVK * iMX RT 1060 EVK * Teensy 4.0 Related to #2492, #2472 and #2477. Fixes #2475.
