WDT with RTC caution!!!
Thanks to Bob,
I almost did implement RTC with WDT. and Now I want to know some caution about this process
1. I implemented 2 years-period timer with RTC. I used WDT2 with my generated interrupt.
but I worried about distortion. because of RTC, WDT2 must operate correctly. so tell me about caution that can distort WDT2.
2. can you tell me about guaranteed error related to RTC? last question, you said RTC could be almost precise. but i doubt that because of
clock accuracy, crystal characteristic or load capacitance.
3. and now I calculate current in circumstance that is between deep sleep and active. but in datasheet. only wake time(25us) existed.
but in order to calculate exact time. I must know about code execution time, deep sleep time, active time during 1s.
