CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=6.0.0-beta.2 2020-09-28T22:22:00+00:00 2020-09-28T22:22:00+00:00 Jeff Epler jepler@gmail.com 2020-09-26T14:44:11+00:00 urn:sha1:a4cc3ad6cb75845e0dc75ede97b8287bb1af0317 This already begins obscuring things, because now there are two sets of shared-module functions for manipulating the same structure, e.g., common_hal_canio_remote_transmission_request_get_id and common_hal_canio_message_get_id 2020-09-23T19:24:02+00:00 Scott Shawcroft scott@adafruit.com 2020-09-23T19:24:02+00:00 urn:sha1:a8558a48ed91f5279a97d4d95669a40224dc6663 makeqstrdefs: don't make _and_, _or_ poisoned substrings for QSTRs 2020-09-22T22:39:44+00:00 Jeff Epler jepler@gmail.com 2020-09-22T22:38:58+00:00 urn:sha1:28e80e47d708fe346be0ae8d430f1a86d5d3049b New contributor @mdroberts1243 encountered an interesting problem in which the argument they had named "column_underscore_and_page_addressing" simply couldn't be used; I discovered that internally this had been transformed into "column_underscore∧page_addressing", because QSTR makes _ENTITY_ stand for the same thing as &ENTITY; does in HTML. This might be nice for some things, but we don't want it here! I was unable to find a sensible way to "escape" and prevent this entity coding, so instead I ripped out support for the _and_ and _or_ escapes. 2020-09-21T21:44:26+00:00 Jeff Epler jepler@gmail.com 2020-09-21T21:42:12+00:00 urn:sha1:4869dbdc670bfa8a5f2e0a639495d03984ea0a6a This reflects our belief that the API is stable enough to avoid incompatible changes during 6.x. 2020-09-21T21:44:26+00:00 Jeff Epler jepler@gmail.com 2020-08-20T16:08:00+00:00 urn:sha1:a2e1867f69ec2d703a9651e5c36a02b0e14dfd9c Tested & working: * Send standard packets * Receive standard packets (1 FIFO, no filter) Interoperation between SAM E54 Xplained running this tree and MicroPython running on STM32F405 Feather with an external transceiver was also tested. Many other aspects of a full implementation are not yet present, such as error detection and recovery. 2020-09-21T21:44:26+00:00 Jeff Epler jepler@gmail.com 2020-09-16T16:57:09+00:00 urn:sha1:e7a213a11420ed362dfb672cd0fa6e77c032fa07 This makes it much easier to implement enums, and the printing code is shared. We might want to convert other enums to this in the future. 2020-09-21T15:03:07+00:00 Jeff Epler jepler@gmail.com 2020-09-21T15:02:27+00:00 urn:sha1:0318eb359fbeb91c6b37ed2050e57711ec2740bc Discord user Folknology encountered a problem building with Python 3.6.9, `TypeError: ord() expected a character, but string of length 0 found`. I was able to reproduce the problem using Python3.5*, and discovered that the meaning of the regular expression `"|."` had changed in 3.7. Before, ``` >>> [m.group(0) for m in re.finditer("|.", "hello")] ['', '', '', '', '', ''] ``` After: ``` >>> [m.group(0) for m in re.finditer("|.", "hello")] ['', 'h', '', 'e', '', 'l', '', 'l', '', 'o', ''] ``` Check if `words` is empty and if so use `"."` as the regular expression instead. This gives the same result on both versions: ``` ['h', 'e', 'l', 'l', 'o'] ``` and fixes the generation of the huffman dictionary. Folknology verified that this fix worked for them. * I could easily install 3.5 but not 3.6. 3.5 reproduced the same problem 2020-09-19T15:16:13+00:00 Jeff Epler jepler@gmail.com 2020-09-19T15:16:13+00:00 urn:sha1:bfbbbd6c5ce58ba1bcb57323566209902e1000b0 This construct (which I added without sufficient testing, apparently) is only supported in Python 3.7 and newer. Make it optional so that this script works on other Python versions. This means that if you have a system with non-UTF-8 encoding you will need to use Python 3.7. In particular, this affects a problem building circuitpython in github's ubuntu-18.04 virtual environment when Python 3.7 is not explicitly installed. cookie-cuttered libraries call for Python 3.6: ``` - name: Set up Python 3.6 uses: actions/setup-python@v1 with: python-version: 3.6 ``` Since CircuitPython's own build calls for 3.8, this problem was not detected. This problem was also encountered by discord user mdroberts1243. The failure I encountered was here: https://github.com/jepler/Jepler_CircuitPython_udecimal/runs/1138045020?check_suite_focus=true .. while my step of "clone and build circuitpython unix port" is unusual, I think the same problem would have affected "build assets" if that step had been reached. 2020-09-16T18:10:22+00:00 Scott Shawcroft scott@adafruit.com 2020-09-16T18:10:22+00:00 urn:sha1:750bc1e04ac6f3c5bec7cb6d5f2bdf1e84c45f47 compression: Implement @ciscorn's dictionary approach 2020-09-16T13:28:15+00:00 Jeff Epler jepler@gmail.com 2020-09-16T12:58:55+00:00 urn:sha1:a8e98cda83119b8716533ce24af6e3d691f7d2ca
