Reading and Writing of external EEPROM
Posted: Mon Oct 09, 2017 12:31 am
Greetings,
I have this DS3231 RTC module sitting around, for the longest time I thought it uses the onboard 24C32 chip for time keeping purposes but apparently its not and the EEPROM, although very small ~30kbit=4kb, can be used freely.
However I'm having a real hard time finding any sort of tutorial or library with examples that works on the ESP32, even tried making it up as I go but being really bad at coding from scratch I frankly have zero clue on how to accomplish this. Does anyone know how to work with such EEPROMs with the ESP32?
