suspect-devices/circuitpython/py/nlr.h, branch 0.8.4CircuitPython - a Python implementation for teaching coding with microcontrollershttps://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=0.8.42016-11-21T22:11:52+00:00This introduces an alternative hardware API called nativeio structured around different functions that are typically accelerated by native hardware. Its not meant to reflect the structure of the hardware.2016-11-21T22:11:52+00:00Scott Shawcroftscott@chickadee.tech2016-11-03T22:50:59+00:00urn:sha1:ccbb5e84f980e252f7380d96fcc5c417a8a64523
Docs are here: http://tannewt-micropython.readthedocs.io/en/microcontroller/
It differs from upstream's machine in the following ways:
* Python API is identical across ports due to code structure. (Lives in shared-bindings)
* Focuses on abstracting common functionality (AnalogIn) and not representing structure (ADC).
* Documentation lives with code making it easy to ensure they match.
* Pin is split into references (board.D13 and microcontroller.pin.PA17) and functionality (DigitalInOut).
* All nativeio classes claim underlying hardware resources when inited on construction, support Context Managers (aka with statements) and have deinit methods which release the claimed hardware.
* All constructors take pin references rather than peripheral ids. Its up to the implementation to find hardware or throw and exception.
py/nlrsetjmp: Update to take into account new location of nlr_top.2016-06-28T10:28:52+00:00Damien Georgedamien.p.george@gmail.com2016-05-30T18:27:26+00:00urn:sha1:94238d4ae5851802db75aa49d4b68bca6f99d6a8
It's now accessed via the MP_STATE_THREAD macro.
py: Wrap all obj-ptr conversions in MP_OBJ_TO_PTR/MP_OBJ_FROM_PTR.2015-11-29T14:25:35+00:00Damien Georgedamien.p.george@gmail.com2015-11-27T17:01:44+00:00urn:sha1:999cedb90ff0827cdb9dfe0e4faa6ebc1739d271
This allows the mp_obj_t type to be configured to something other than a
pointer-sized primitive type.
This patch also includes additional changes to allow the code to compile
when sizeof(mp_uint_t) != sizeof(void*), such as using size_t instead of
mp_uint_t, and various casts.
py: Guard against redef of nlr_push with DEBUG + MICROPY_NLR_SETJMP.2015-03-03T14:34:40+00:00stijnstinos@zoho.com2015-03-03T10:15:06+00:00urn:sha1:803264bb17a1dca212e427750fde2cdac98b36f0nlr: Add even more optional debugging logging.2015-02-15T17:28:18+00:00Paul Sokolovskypfalcon@users.sourceforge.net2015-02-15T17:28:18+00:00urn:sha1:3077fbff262fd64b5e71c8f7a4e33e0c0c949ca5
Has to be enabled by manual editing, but at least it's there, as debugging
NLR issues may be weird.
nlr: If DEBUG, guard against recursive nlr_push().2015-02-15T17:23:52+00:00Paul Sokolovskypfalcon@users.sourceforge.net2015-02-15T17:23:52+00:00urn:sha1:e89cc13e5c4fa05d7f14dabedf3ac21a2dd57084
Pushing same NLR record twice would lead to "infinite loop" in nlr_jump
(but more realistically, it will crash as soon as NLR record on stack is
overwritten).
py: Put all global state together in state structures.2015-01-07T20:33:00+00:00Damien Georgedamien.p.george@gmail.com2015-01-01T23:30:53+00:00urn:sha1:b4b10fd350852e321624d74983cca286091b55a1
This patch consolidates all global variables in py/ core into one place,
in a global structure. Root pointers are all located together to make
GC tracing easier and more efficient.
py: Move global variable nlr_top to one place, in a .c file.2015-01-01T21:47:58+00:00Damien Georgedamien.p.george@gmail.com2015-01-01T21:47:58+00:00urn:sha1:8a2347723eba9899a12799021b4e47bd1fa20282
This reduces dependency on assembler, and allows to consolidate global
variables in the future.
py: Move to guarded includes, everywhere in py/ core.2015-01-01T20:32:09+00:00Damien Georgedamien.p.george@gmail.com2015-01-01T20:27:54+00:00urn:sha1:51dfcb4bb7613ed164952712d9a5235a7b833cde
Addresses issue #1022.
