suspect-devices/circuitpython/py, branch 4.0.0-alpha.4 CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=4.0.0-alpha.4 2018-12-06T22:24:20+00:00 Rework safe mode and have heap overwrite trigger it. 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. Add stack validity check and raise an error when it happens. 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. UART changes: timeout in secs, write bytes, etc. 2018-12-03T17:04:32+00:00 Dan Halbert halbert@halwitz.org 2018-12-03T16:00:35+00:00 urn:sha1:80db2cec99ca5c995a0302b1d6d00ad77cfcd736 Add support for adding release info into adafruit/circuitpython-org 2018-11-30T08:30:57+00:00 Scott Shawcroft scott@tannewt.org 2018-11-29T00:58:44+00:00 urn:sha1:9d07e95351f692167a2e178b06311f17d0767df4 This also changes the build script to python with better output. Support OSError attributes 2018-11-13T21:04:44+00:00 Noralf Trønnes noralf@tronnes.org 2018-11-12T15:16:47+00:00 urn:sha1:c5aa2e93001436f6d63e3e9b7dff3c535397db1c This adds support for the OSError attributes : errno, strerror, filename and filename2. CPython only sets errno if 2 arguments has been passed in. This has not been implemented here. CPython OSError.args is capped at 2 items for backward compatibility reasons. This has not been implemented here. MICROPY_CPYTHON_COMPAT has to be enabled to get these attributes. mp_common_errno_to_str() has been extended to check mp_errno_to_str() as well. This is done to ease reuse for the strerror argument. Fix output overflow and make help translatable 2018-11-10T00:41:08+00:00 Scott Shawcroft scott@tannewt.org 2018-11-10T00:41:08+00:00 urn:sha1:355abc835ea75715b4dea38604ef64f8c4eeaa0f Build refinement to handle warnings and quiet output 2018-11-09T08:11:43+00:00 Scott Shawcroft scott@tannewt.org 2018-11-09T08:11:43+00:00 urn:sha1:168e23e466737fd25d6c7a524231781e35d1d49a Merge pull request #1167 from notro/cpython_stdlib 2018-10-24T19:57:41+00:00 Scott Shawcroft scott@tannewt.org 2018-10-24T19:57:41+00:00 urn:sha1:dc9d338612284ab42d6adb0da95ad64dcd6b4cd9 Support CPython standard library Use python3 for mpy-tool 2018-10-18T17:37:42+00:00 Scott Shawcroft scott@tannewt.org 2018-10-18T17:37:42+00:00 urn:sha1:cb0126131a08a52aa5f66ae0f705079b2ae21080 Add debug info to the generated frozen_mpy.c 2018-10-18T00:45:47+00:00 Scott Shawcroft scott@tannewt.org 2018-10-18T00:45:47+00:00 urn:sha1:4f9c8b7361db7967fa794ea4d911ef350f23061a It adds size info and uses macros for byte code to make it more readable.
