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.
|
||
|
|
|
||
|
|
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
|
||
|
|
|
||
|
|
.. 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
