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

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.
