ESP8266 Community Forum

Hi,

I am trying to set up an external eeprom for the ESP8266. But I had some problems using the library extEEPROM. When using the example I get the error:

"eepromTest:21: error: 'twiClock400kHz' was not declared in this scope"

I don't know how to fix that. Is there a good tutorial for using external eeprom or any ideas?

Thanks and best regards,
Sebastian

That library would require some modifications for it to work with the ESP8266. Try this one https://github.com/Naguissa/uRTCLib

I know it's an old topic, but I think this may be interesting.

I'm uRTCLib creator and, seeing EEPROM functionality has been expanded and is very useful with other I2C EEPROMS than RTC's ones, I splitted the library and created one specifically for the EEPROMs. It's called uEEPROMLib and can be found here: https://github.com/Naguissa/uEEPROMLib

Shoud be available on IDE's Library Manager in few hours.
