esp8266 internal RTC
Posted: Thu Feb 19, 2015 4:14 pm
rtc_time2 = system_get_rtc_time();and
system_rtc_mem_read(0, &rtc_reg_val, 4)
both return 4bytes.
Now RTC's often have registers that contain a representation of the day,month, year, hour, min, and second
system_get_rtc_time looks like counter in the way that system_get_time() returns a 32bit counter.
Question:
Is the esp8266's internal RTC just a counter incremented on a quanta of instruction cycles that differs from the
system_get_time() counter in only in the fact that it keeps running during sleep?
Or is it a RTC like a Dallas DS1307 that has day,month, year, hour, min, and second?
