Example usage:: rtc = pyb.RTC() rtc.datetime((2014, 5, 1, 4, 13, 0, 0, 0)) print(rtc.datetime()) Constructors ------------ .. class:: pyb.RTC() Create an RTC object. Methods ------- .. method:: rtc.datetime([datetimetuple]) Get or set the date and time of the RTC. With no arguments, this method returns an 8-tuple with the current date and time. With 1 argument (being an 8-tuple) it sets the date and time. .. only:: port_pyboard The 8-tuple has the following format: (year, month, day, weekday, hours, minutes, seconds, subseconds) ``weekday`` is 1-7 for Monday through Sunday. ``subseconds`` counts down from 255 to 0 .. only:: port_pyboard .. method:: rtc.wakeup(timeout, callback=None) Set the RTC wakeup timer to trigger repeatedly at every ``timeout`` milliseconds. This trigger can wake the pyboard from both the sleep states: :meth:`pyb.stop` and :meth:`pyb.standby`. If ``timeout`` is ``None`` then the wakeup timer is disabled. If ``callback`` is given then it is executed at every trigger of the wakeup timer. ``callback`` must take exactly one argument. .. method:: rtc.info() Get information about the startup time and reset source. - The lower 0xffff are the number of milliseconds the RTC took to start up. - Bit 0x10000 is set if a power-on reset occurred. - Bit 0x20000 is set if an external reset occurred .. method:: rtc.calibration(cal) Get or set RTC calibration. With no arguments, ``calibration()`` returns the current calibration value, which is an integer in the range [-511 : 512]. With one argument it sets the RTC calibration. The RTC Smooth Calibration mechanism addjusts the RTC clock rate by adding or subtracting the given number of ticks from the 32768 Hz clock over a 32 second period (corresponding to 2^20 clock ticks.) Each tick added will speed up the clock by 1 part in 2^20, or 0.954 ppm; likewise the RTC clock it slowed by negative values. The usable calibration range is: (-511 * 0.954) ~= -487.5 ppm up to (512 * 0.954) ~= 488.5 ppm @ 1.1.1.1 log @Import micropython version 1.5.2 into othersrc. Micropython is a python3 implementation that has been optimised for micro-controllers and small embedded systems. It also has a "unix" port. It has an MIT license. This is version 1.5.2 of micropython. MicroPython implements the entire Python 3.4 syntax (including exceptions, "with", "yield from", etc.). The following core datatypes are provided: str (including basic Unicode support), bytes, bytearray, tuple, list, dict, set, frozenset, array.array, collections.namedtuple, classes and instances. Builtin modules include sys, time, and struct. Note that only subset of Python 3.4 functionality implemented for the data types and modules. This is the standard micropython source (version v1.5.2), which has been adapted to use reachover infrastructure. At the present time, libffi (from pkgsrc) is used. Alternative locations for libffi can be set using the PKGSRC_PREFIX definition to make. In the whole scheme of things, micropython is quite small: % size bin/micropython text data bss dec hex filename 393495 1624 2208 397327 6100f bin/micropython % and runs much as expected: % bin/micropython MicroPython v1.5.2 on 2016-01-13; linux version Use Ctrl-D to exit, Ctrl-E for paste mode >>> print("hello world") hello world >>> list(5 * x + y for x in range(10) for y in [4, 2, 1]) [4, 2, 1, 9, 7, 6, 14, 12, 11, 19, 17, 16, 24, 22, 21, 29, 27, 26, 34, 32, 31, 39, 37, 36, 44, 42, 41, 49, 47, 46] >>> % python2.7 Python 2.7.10 (default, Oct 17 2015, 17:55:29) [GCC 4.8.5] on netbsd7 Type "help", "copyright", "credits" or "license" for more information. >>> print("hello world") hello world >>> list(5 * x + y for x in range(10) for y in [4, 2, 1]) [4, 2, 1, 9, 7, 6, 14, 12, 11, 19, 17, 16, 24, 22, 21, 29, 27, 26, 34, 32, 31, 39, 37, 36, 44, 42, 41, 49, 47, 46] >>> ^D % This (reachover) version runs all the tests which the gmake version does. % make t cd bin && make t cd /home/agc/local/micropython/bin/../dist/unix/../tests && env MICROPY_MICROPYTHON=/home/agc/local/micropython/bin/micropython ./run-tests pass basics/0prelim.py pass basics/andor.py pass basics/array1.py pass basics/array_add.py pass basics/array_construct.py pass basics/array_construct2.py ... pass unix/ffi_callback.py pass unix/ffi_float.py pass unix/ffi_float2.py 474 tests performed (15812 individual testcases) 474 tests passed 5 tests skipped: cmd_showbc cmd_verbose machine1 machine_mem extra_coverage % The sources are available from github: https://github.com/micropython/micropython micropython release at: https://github.com/micropython/micropython/releases Sources for 1.5.2 taken from: https://github.com/micropython/micropython/archive/v1.5.2.tar.gz Alistair Crooks agc@@netbsd.org Wed Jan 13 17:15:30 PST 2016 @ text @@
