#74715 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

#77444 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.
