Reproducer code was to play a 22.05kHz sample and repeatedly print `os.listdir('')` 2019-05-14T22:15:23+00:00 Scott Shawcroft scott@tannewt.org 2019-05-14T22:15:23+00:00 urn:sha1:b7b55e0c0a0187f4d248d9b52cd972af5d928336 Fixes #1694 2018-12-06T22:24:20+00:00 Scott Shawcroft scott@tannewt.org 2018-12-06T22:24:20+00:00 urn:sha1:6ef863997186e1893cdf19c0e04d0a8a3f33ad9d This creates a common safe mode mechanic that ports can share. As a result, the nRF52 now has safe mode support as well. The common safe mode adds a 700ms delay at startup where a reset during that window will cause a reset into safe mode. This window is designated by a yellow status pixel and flashing the single led three times. A couple NeoPixel fixes are included for the nRF52 as well. Fixes #1034. Fixes #990. Fixes #615. 2018-12-05T07:26:04+00:00 Scott Shawcroft scott@tannewt.org 2018-10-23T00:57:28+00:00 urn:sha1:7ad2e6ace34a6d417ec1b84472fa409d5451137b The backtrace cannot be given because it relies on the validity of the qstr data structures on the heap which may have been corrupted. In fact, it still can crash hard when the bytecode itself is overwritten. To fix, we'd need a way to skip gathering the backtrace completely. This also increases the default stack size on M4s so it can accomodate the stack needed by ASF4s nvm API. 2018-08-17T00:40:57+00:00 Scott Shawcroft scott@tannewt.org 2018-08-16T01:32:37+00:00 urn:sha1:de5a9d72dcdaacdd5048195cd5bab007f4b2baef This saves code space in builds which use link-time optimization. The optimization drops the untranslated strings and replaces them with a compressed_string_t struct. It can then be decompressed to a c string. Builds without LTO work as well but include both untranslated strings and compressed strings. This work could be expanded to include QSTRs and loaded strings if a compress method is added to C. Its tracked in #531. 2018-08-09T20:29:30+00:00 Scott Shawcroft scott@tannewt.org 2018-08-09T01:24:49+00:00 urn:sha1:96ebf5bc3fb455162286b9bc31e763f3c4f1c457 * Fix finding translations with escaped characters. * Add back \r to translations since its needed by screen. 2017-10-25T05:31:16+00:00 Scott Shawcroft scott.shawcroft@gmail.com 2017-10-25T05:31:16+00:00 urn:sha1:73c15dcf8b1b927757a595a867334b38355ddb8f This is prep for merging in the NRF5 pull request. 2017-10-04T01:37:50+00:00 Damien George damien.p.george@gmail.com 2017-10-04T01:37:50+00:00 urn:sha1:a3dc1b1957d2c96d7c60c2c629c95077b03488a1 Header files that are considered internal to the py core and should not normally be included directly are: py/nlr.h - internal nlr configuration and declarations py/bc0.h - contains bytecode macro definitions py/runtime0.h - contains basic runtime enums Instead, the top-level header files to include are one of: py/obj.h - includes runtime0.h and defines everything to use the mp_obj_t type py/runtime.h - includes mpstate.h and hence nlr.h, obj.h, runtime0.h, and defines everything to use the general runtime support functions Additional, specific headers (eg py/objlist.h) can be included if needed. 2017-09-04T04:16:27+00:00 Damien George damien.p.george@gmail.com 2017-09-04T04:16:27+00:00 urn:sha1:d4b75f6b6822885e331c69a74e56e23af40a6264 IEEE floating point is specified such that a comparison of NaN with itself returns false, and Python respects these semantics. This patch makes uPy also have these semantics. The fix has a minor impact on the speed of the object-equality fast-path, but that seems to be unavoidable and it's much more important to have correct behaviour (especially in this case where the wrong answer for nan==nan is silently returned).
