Using the RTC

[jgriessen]

I found a post from a year ago where they changed this in main.c to get RTC going:

Code: Select all

main.c:    rtc_init_start(false);

Is that still required?

Testing similar to
viewtopic.php?f=12&t=3086&hilit=RTC+set ... =10#p18398

shows that main.c is OK as is now -- the RTC is counting,
and calling

Code: Select all

rtc = pyb.RTC()
rtc.init()

stops the RTC now where it was running before that command.

Perhaps the C code is hardware dependent?

As for the Python I've never initialised it on a Pyboard and never knew it had an init method. I just instantiate the RTC and, if it's not battery-backed, set it.

Yes, I'm doing that and getting results. The rtc.init() was from a while back searching through the forum posts.
