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. stmhal: Add rtc.init() method to force RTC to re-initialise. 2015-12-04T12:05:05+00:00 Damien George damien.p.george@gmail.com 2015-12-04T12:05:05+00:00 urn:sha1:f7697ff393fa60e2b9adea31960ca17afc1d2ab7 stmhal: Implement delayed RTC initialization with LSI fallback. 2015-11-23T23:23:07+00:00 T S tsp@esg-workstation.com 2015-11-07T11:03:12+00:00 urn:sha1:86aa16bea61da8a8d156a7a928902a0bf4c85b73 If RTC is already running at boot then it's left alone. Otherwise, RTC is started at boot but startup function returns straight away. RTC startup is then finished the first time it is used. Fallback to LSI if LSE fails to start in a certain time. Also included: MICROPY_HW_CLK_LAST_FREQ hold pyb.freq() parameters in RTC backup reg MICROPY_HW_RTC_USE_US option to present datetime sub-seconds in microseconds MICROPY_HW_RTC_USE_CALOUT option to enable RTC calibration output CLK_LAST_FREQ and RTC_USE_CALOUT are enabled for PYBv1.0. stmhal: Fix RTC code to work on the F7 2015-11-07T17:42:26+00:00 Dave Hylands dhylands@gmail.com 2015-11-07T17:42:26+00:00 urn:sha1:57e00ef26236264bc54ad32442df5854aa0df27b stmhal/rtc: LSx oscillator is only initialized upon initial power up. 2015-11-06T22:00:34+00:00 T S tsp@esg-workstation.com 2015-11-01T13:31:44+00:00 urn:sha1:8f7ff854b0e341aa49d198a93fea7e83dd4cc71c Initial power up also includes VBAT. If LSE is configured but fails to start, LSI is used until next full power cycle. Also handles STM32F7xx variant. stmhal: Add symbolic #defines for interrupt levels in irq.h. 2015-11-01T23:23:39+00:00 Dave Curtis davecurtis@sonic.net 2015-10-31T17:44:20+00:00 urn:sha1:32b3549cce7a965d92a81db02c7adc973f08d74c stmhal: f7: Fix recent RTC change to build on F7. 2015-10-30T23:40:00+00:00 Dave Hylands dhylands@gmail.com 2015-10-30T22:15:25+00:00 urn:sha1:165734522ee48f4452125d9c56b1a9e41d24f630 stmhal: Make RTC init skip startup if LTE is already enabled and ready. 2015-10-30T13:13:42+00:00 Peter Hinch peter@hinch.me.uk 2015-10-27T10:55:47+00:00 urn:sha1:38196344691ad32b7f80bb44489c069ceaecb1ec This prevents the loss of RTC time when exiting from standby mode, since the RTC is paused while it is being re-inited and this loses about 120ms. Thanks to @chuckbook for the patch.
