This reduces base GC time from 1700ms to 900ms. stmhal: Prefix includes with py/; remove need for -I../py. 2015-01-01T21:06:20+00:00 Damien George damien.p.george@gmail.com 2015-01-01T21:06:20+00:00 urn:sha1:2cf6dfa280a8149941aafc852fbaae8bdfc4999e modsys: Add sys.print_exception(exc, file=sys.stdout) function. 2014-12-08T20:25:49+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-12-06T12:29:09+00:00 urn:sha1:46c3ab20049af16e97863e90e5761fae329f872a The function is modeled after traceback.print_exception(), but unbloated, and put into existing module to save overhead on adding another module. Compliant traceback.print_exception() is intended to be implemented in micropython-lib in terms of sys.print_exception(). This change required refactoring mp_obj_print_exception() to take pfenv_t interface arguments. Addresses #751. Add support for complimentary channel output and deadtime. 2014-10-10T20:54:03+00:00 Dave Hylands dhylands@gmail.com 2014-10-10T16:56:41+00:00 urn:sha1:1c795445b31a73bcff71eac4ce56827554b4f29f This patch enables output on the complimentary channels (TIMx_CHyN). For timers 1 and 8, deadtime can also be inserted when the channels transition. For the pyboard, TIM8_CH1/CH1N and TIM8_CH2/CH2N can take advantage of this. stmhal: Use mp_uint_t where appropriate. 2014-10-05T20:51:54+00:00 Damien George damien.p.george@gmail.com 2014-10-05T20:51:54+00:00 urn:sha1:d03c6816083c8ce8a35d278ede48c4089012b055 Found these by compiling stmhal with mp_uint_t of type uint32_t instead of unsigned int. This actually makes a difference to the code, but just a curiosity. stmhal, timer: Fix timer.chanel so mode can be a keyword. 2014-10-05T16:52:45+00:00 Damien George damien.p.george@gmail.com 2014-10-04T14:25:01+00:00 urn:sha1:ba0383a8c7b2fb394a7d2bc7a67cab7fc3200263 stmhal, timer: Improve accuracy of freq computation. 2014-10-05T16:52:45+00:00 Damien George damien.p.george@gmail.com 2014-10-04T13:59:35+00:00 urn:sha1:55f68b3ce809cb6331fb500fa10331b16cbc6c13 stmhal, timer: Set freq from float; get timer source freq. 2014-10-05T16:52:44+00:00 Damien George damien.p.george@gmail.com 2014-10-04T13:36:39+00:00 urn:sha1:97ef94df83238e58fd7a084c3ca0e8af164136e0 Timers now have the following new features: - can init freq using floating point; eg tim.init(freq=0.1) - tim.source_freq() added to get freq of timer clock source - tim.freq() added to get/set freq - print(tim) now prints freq
