2020-09-08Fix decompression of unicode values above 2047Jeff Epler
Two problems: The lead byte for 3-byte sequences was wrong, and one mid-byte was not even filled in due to a missing "++"! Apparently this was broken ever since the first "Compress as unicode, not bytes" commit, but I believed I'd "tested" it by running on the Pinyin translation. This rendered at least the Korean and Japanese translations completely illegible, affecting 5.0 and all later releases.

2020-04-17RGBMatrix: finish renaming from ProtomatterJeff Epler
This gets all the purely internal references. Some uses of protomatter/Protomatter/PROTOMATTER remain, as they are references to symbols in the Protomatter C library itself.

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.

2019-12-10supervisor: external_flash: don't call m_free when it's badJeff Epler
It's extremely dubious that we have these handles that we think are to GC'd memory at a time when the gc pool may not be initialized. Hopefully, they WERE valid GC memory and are undisturbed by the teardown of the interpreter that can lead to this state. In this case, don't try to m_free them, the memory will become free when the GC heap is reinitialized. Closes: #2338 (together with previous commit)

translation: Compress as unicode, not bytes
2019-12-02translation: Compress as unicode, not bytesJeff Epler
By treating each unicode code-point as a single entity for huffman compression, the overall compression rate can be somewhat improved without changing the algorithm. On the decompression side, when compressed values above 127 are encountered, they need to be converted from a 16-bit Unicode code point into a UTF-8 byte sequence. Doing this returns approximately 1.5kB of flash storage with the zh_Latn_pinyin translation. (292 -> 1768 bytes remaining in my build of trinket_m0) Other "more ASCII" translations benefit less, and in fact zh_Latn_pinyin is no longer the most constrained translation! (de_DE 1156 -> 1384 bytes free in flash, I didn't check others before pushing for CI) English is slightly pessimized, 2840 -> 2788 bytes, probably mostly because the "values" array was changed from uint8_t to uint16_t, which is strictly not required for an all-ASCII translation. This could probably be avoided in this case, but as English is not the most constrained translation it doesn't really matter. Testing performed: built for feather nRF52840 express and trinket m0 in English and zh_Latn_pinyin; ran and verified the localized messages such as Àn xià rènhé jiàn jìnrù REPL. Shǐyòng CTRL-D chóngxīn jiāzài. and Press any key to enter the REPL. Use CTRL-D to reload. were properly displayed.
