Hi,

I need a sync pulse every minute at start of minute, aligned with UTC time 
(let's not discuss what UTC time really is :-)). Any quick assessment whether 
uBlox TIMEPULSE out can do this?


It does not seem to be a problem to generate a pulse every minute based on 
UBX-CFG-TP5, but how can this be aligned with a minute. Is the only solution to 
query time eg every top of second to see if minute has started?


I can parse this out of the GPS data even by polling but this seems ... not 
elegant.


A few 10s of millsecond after exact start of minute would be fine. Thoughts? 
Target CPU is very limited, say ATmega328. Or none at all if it can be avoided.
