Hello eerybody! 
I'm triyng to build a simple project with an Arduino Uno, an ESP8266-01 and an eeprom 25lc256.
Arduino should write the eeprom memory with some data and the esp should be read trought i2c bus and build a simple http page.
at this time the arduino is writing data correctly but the esp can't read data if the atmega328 is connected.
I already try to define the arduino as i2c slave but without success.
I use the latest NodeMCU custom build.
Any ideas?
PS: I have also an OLED display attached trought i2c bus.
have a good day
