suspect-devices/circuitpython/teensy/main.c, branch v1.8.6 CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=v1.8.6 2016-10-14T05:46:34+00:00 py/vstr: Combine vstr_new_size with vstr_new since they are rarely used. 2016-10-14T05:46:34+00:00 Damien George damien.p.george@gmail.com 2016-10-14T05:46:34+00:00 urn:sha1:824f5c5a32d740acad50d23b7ab1d69660dcf3ad Now there is just one function to allocate a new vstr, namely vstr_new (in addition to vstr_init etc). The caller of this function should know what initial size to allocate for the buffer, or at least have some policy or config option, instead of leaving it to a default (as it was before). teensy: Fix execution of frozen boot.py and main.py 2016-08-22T02:31:33+00:00 Dave Hylands dhylands@gmail.com 2016-08-20T04:09:52+00:00 urn:sha1:253e1a6f6771c09db742c22a25ab53ffbd68eab2 py/runtime: mp_stack_ctrl_init() should be called immediately on startup. 2016-01-29T00:13:42+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-01-28T23:05:53+00:00 urn:sha1:d3b1f0b627ccc6705d9fe958549badb87a74ded1 Calling it from mp_init() is too late for some ports (like Unix), and leads to incomplete stack frame being captured, with following GC issues. So, now each port should call mp_stack_ctrl_init() on its own, ASAP after startup, and taking special precautions so it really was called before stack variables get allocated (because if such variable with a pointer is missed, it may lead to over-collecting (typical symptom is segfaulting)). lib/utils: Add pyexec_frozen_module to load and execute frozen module. 2015-12-26T12:32:33+00:00 Damien George damien.p.george@gmail.com 2015-12-26T12:32:33+00:00 urn:sha1:84b245f187f9711357b1fd46bebc67266bd028e5 This is a convenience function similar to pyexec_file. It should be used instead of raw mp_parse_compile_execute because the latter does not catch and report exceptions. lib/pyexec: Move header pyexec.h from stmhal directory. 2015-11-09T13:13:09+00:00 Damien George damien.p.george@gmail.com 2015-11-09T13:13:09+00:00 urn:sha1:40274fec9c0f8e1ce06f999927f550106b9aa5e8 teensy: Switch over to using frozen modules instead of memzip 2015-11-04T14:21:21+00:00 Dave Hylands dhylands@gmail.com 2015-11-01T05:55:13+00:00 urn:sha1:53ea2b5ce2f7088c871c6c264899e4eae7973859 I left memzip in for the time being, so you can choose in the Makefile whether to USE_FROZEN or USE_MEMZIP. It looks like using frozen saves about 2472 bytes (using my set of 15 python files), mostly due to overheads in the zip file format. all: Add py/mphal.h and use it in all ports. 2015-10-31T16:14:30+00:00 Damien George damien.p.george@gmail.com 2015-10-30T23:03:58+00:00 urn:sha1:731f359292c0e2630873df1a19c5baac7287024f py/mphal.h contains declarations for generic mp_hal_XXX functions, such as stdio and delay/ticks, which ports should provide definitions for. A port will also provide mphalport.h with further HAL declarations. stmhal: Make pybstdio usable by other ports, and use it. 2015-02-13T15:04:53+00:00 Damien George damien.p.george@gmail.com 2015-02-13T15:04:53+00:00 urn:sha1:0b32e50365b6e36474e183a7240ccfc8fa56830a Now all ports can use pybstdio.c to provide sys.stdin/stdout/stderr, so long as they implement mp_hal_stdin_* and mp_hal_stdout_* functions. py: Change vstr_null_terminate -> vstr_null_terminated_str, returns str. 2015-01-29T13:57:23+00:00 Damien George damien.p.george@gmail.com 2015-01-29T13:57:23+00:00 urn:sha1:827b0f747b2aa4870ef8de90cb0c3a4151e5ce71 py: Change vstr so that it doesn't null terminate buffer by default. 2015-01-28T23:43:01+00:00 Damien George damien.p.george@gmail.com 2015-01-28T23:43:01+00:00 urn:sha1:0d3cb6726ddc1bab9fdd11a0aaa259fb436da4b2 This cleans up vstr so that it's a pure "variable buffer", and the user can decide whether they need to add a terminating null byte. In most places where vstr is used, the vstr did not need to be null terminated and so this patch saves code size, a tiny bit of RAM, and makes vstr usage more efficient. When null termination is needed it must be done explicitly using vstr_null_terminate.
