Hi all,
How would you go about generating approx 1Hz signal with minimum number of external (to picaxe) components? I understand, I can use RTC for this - there are many with configurable freq outputs and integrated 32....kHz crystals these days. However, since I do not have backup power, I don't have any good use for the rest of the RTC functionality and tiny (the only suitable) versions are not very cheap.
Intuitively a picaxe comparator with resistor+capacitor could be one thinking direction, but I must confess my analog electronics design skills are not much .
Thank you for your time,
Edmunds
