RTC Library bug???
Posted: Sun Jun 14, 2015 4:37 amHello,
I was reading up on how to use the RTC inside the ESP8266 and looking into the eagle_soc.h file, it seems like there is a "bug" where the RTC values are in fact read from Timer2.
On line 67:
On Line 150:
On line 169:
Anyone else tried using the RTC successfully?
I suppose the system calls (system_get_rtc_time) are compiled based on this, so it's really not the RTC working and without more information about the registers of the RTC there isn't much else we can do I guess.
Anyone else noticed this before??
