CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=v1.5.2 2015-12-09T19:43:28+00:00 2015-12-09T19:43:28+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2015-12-09T19:39:36+00:00 urn:sha1:d4a874b81e29008713e9de2dd623e62c9f2aa5dc Previously, sizeof() blindly assumed LAYOUT_NATIVE and tried to align size even for packed LAYOUT_LITTLE_ENDIAN & LAYOUT_BIG_ENDIAN. As sizeof() is implemented on a strucuture descriptor dictionary (not an structure object), resolving this required passing layout type around. 2015-12-03T22:59:08+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2015-12-03T22:58:46+00:00 urn:sha1:add6f4556ed743e150db3a52f2dcab221ff731f1 2015-11-29T14:25:35+00:00 Damien George damien.p.george@gmail.com 2015-11-27T17:01:44+00:00 urn: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. 2015-11-29T14:25:04+00:00 Damien George damien.p.george@gmail.com 2015-11-27T13:38:15+00:00 urn:sha1:cbf7674025814797f5c537d6d1c195efe58ccaaf 2015-10-27T21:21:42+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2015-10-27T21:21:28+00:00 urn:sha1:20f85feecc5ea42406f5c37194f6b831d574824e Since we now have it. 2015-10-25T22:03:24+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2015-10-25T22:02:27+00:00 urn:sha1:393d0c16799a4eda787886bc0c7fce0da3c4adb8 This is required to write structures to files, pass to FFI functions, etc. 2015-06-06T19:57:54+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2015-06-06T19:57:31+00:00 urn:sha1:1679696612007107dac55d936006b1923eda2475 Now address comes first, and args related to struct type are groupped next. Besides clear groupping, should help catch errors eagerly (e.g. forgetting to pass address will error out). Also, improve args number checking/reporting overall. 2015-04-16T14:30:16+00:00 Damien George damien.p.george@gmail.com 2015-04-09T22:56:15+00:00 urn:sha1:7f9d1d6ab923096582622b700bedb6a571518eac Previous to this patch the printing mechanism was a bit of a tangled mess. This patch attempts to consolidate printing into one interface. All (non-debug) printing now uses the mp_print* family of functions, mainly mp_printf. All these functions take an mp_print_t structure as their first argument, and this structure defines the printing backend through the "print_strn" function of said structure. Printing from the uPy core can reach the platform-defined print code via two paths: either through mp_sys_stdout_obj (defined pert port) in conjunction with mp_stream_write; or through the mp_plat_print structure which uses the MP_PLAT_PRINT_STRN macro to define how string are printed on the platform. The former is only used when MICROPY_PY_IO is defined. With this new scheme printing is generally more efficient (less layers to go through, less arguments to pass), and, given an mp_print_t* structure, one can call mp_print_str for efficiency instead of mp_printf("%s", ...). Code size is also reduced by around 200 bytes on Thumb2 archs. 2015-04-11T15:54:37+00:00 Damien George damien.p.george@gmail.com 2015-04-01T14:10:50+00:00 urn:sha1:b1bbe966c408901ae64ea8c8b468694c47d05b1a This simplifies the API for objects and reduces code size (by around 400 bytes on Thumb2, and around 2k on x86). Performance impact was measured with Pystone score, but change was barely noticeable. 2015-01-20T12:47:20+00:00 Damien George damien.p.george@gmail.com 2015-01-20T12:47:20+00:00 urn:sha1:ff8dd3f486afb0d6ff1427d8a6a8a8ed73baa660 See issue #699.
