Therefore, we have to adjust delta in RTC memory before going into deepsleep to get almost correct time after waking up.

Let's write the last state of system_get_rtc_time() in RTC mem and use it to check for overflow. This commit require running pyb_rtc_get_us_since_2000() at least once within 7 hours to avoid overflow. 2016-06-01T10:33:04+00:00 Damien George damien.p.george@gmail.com 2016-06-01T10:33:04+00:00 urn:sha1:752e952096815adc2e418967e4b056680924a584 So that RTC.memory() returns b'' on power up if it was never set.

Use the RTC to configure the alarm to wake the device. Basic use is the following: import machine # configure RTC's ALARM0 to wake device from deep sleep rtc = machine.RTC() rtc.irq(trigger=rtc.ALARM0, wake=machine.DEEPSLEEP) # do other things # ... # set ALARM0's alarm to wake after 10 seconds rtc.alarm(rtc.ALARM0, 10000) # enter deep-sleep state (system is reset upon waking) machine.deepsleep() To detect if the system woke from a deep sleep use: if machine.reset_cause() == machine.DEEPSLEEP_RESET: print('woke from deep sleep') 2016-03-04T14:49:01+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-02-08T19:43:37+00:00 urn:sha1:a4c8ef9d16d45c58bbfc0aba451e4c197c552f0f Initialize RTC period coefficients, etc. if RTC RAM doesn't contain valid values. time.time() then will return number of seconds since power-on, unless set to different timebase. This reuses MEM_MAGIC for the purpose beyond its initial purpose (but the whole modpybrtc.c need to be eventually reworked completely anyway). 2016-02-12T21:20:52+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-02-12T21:20:52+00:00 urn:sha1:a2e39a756c45b388f61fae02b20602f8cc0e5f1d 2016-02-08T19:39:33+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-02-08T19:35:36+00:00 urn:sha1:814b1ae3a9fbe5779ad24f481331e3567dce86bb 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. 2015-06-22T22:03:17+00:00 Damien George damien.p.george@gmail.com 2015-06-22T22:03:17+00:00 urn:sha1:de8b585ab7436db3acac3a6a32b50a594729fea9 This is the standard way of doing things, one should construct a peripheral object (even if it's a singleton).
