CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=cross 2016-01-11T00:49:27+00:00 2016-01-11T00:49:27+00:00 Damien George damien.p.george@gmail.com 2016-01-03T15:55:55+00:00 urn:sha1:5b3f0b7f39bd67cc9182993c288f09f67a0890df The first argument to the type.make_new method is naturally a uPy type, and all uses of this argument cast it directly to a pointer to a type structure. So it makes sense to just have it a pointer to a type from the very beginning (and a const pointer at that). This patch makes such a change, and removes all unnecessary casting to/from mp_obj_t. 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. 2015-10-19T21:50:59+00:00 Damien George damien.p.george@gmail.com 2015-10-19T21:48:21+00:00 urn:sha1:2f96b1982a84b21788756d9220b5c4ead657e8f7 Looks like we can use the same Pin class for legacy pyb module and new machine module. 2015-10-11T12:18:15+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2015-10-11T09:09:43+00:00 urn:sha1:1b586f3a734c27c78080fb2173bbde17168cb9e4 2015-08-02T23:14:48+00:00 Damien George damien.p.george@gmail.com 2015-08-02T23:05:16+00:00 urn:sha1:0851751615580d02bd6f841e13651923f05fde59 Extracted GPIO clock enable logic into mp_hal_gpio_clock_enable and called from anyplace which might need to use GPIO functions on ports other than A-D.

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. 2015-01-07T23:38:50+00:00 Damien George damien.p.george@gmail.com 2015-01-07T23:38:50+00:00 urn:sha1:3b51b3e90f1d513031ad2c6b6a2a0d5d391f753d A GC in stmhal port now only scans true root pointers, not entire BSS. This reduces base GC time from 1700ms to 900ms. 2015-01-01T21:13:30+00:00 Damien George damien.p.george@gmail.com 2015-01-01T21:13:30+00:00 urn:sha1:b68d98d61cc013da2df98e5d77d7bf3598d0dd4d
