I am trying to use EEPROM library from Arduino framework for my ESP8266 project (NodeMCU). I am using Atom with Platformio.

Initialization of EEPROM is attempted at void setup() in main.cpp:

EEPROM.begin(80);

The compiler throws an error at this line with:

request for member 'begin' in '0', which is of non-class type 'int'

This is strange as I just follow a simple example from GitHub.

I include <EEPROM.h> just as <Arduino.h> and many others (<ESP8266WiFi.h>, <ESP8266WebServer.h>, <ESP8266mDNS.h>). Platformio has created .pio\build\nodemcuv2\lib32c\EEPROM directory with EEPROM.cpp.o inside but compilation fails.

How can I make it work and what else should I check to find the problem?

    Instead of describing your code, show your code. Commented Aug 15, 2020 at 18:55

    Then write some code that is only a few lines and demonstrates the problem. Commented Aug 15, 2020 at 19:08

    Exactly what @Majenko said - if this is a problem then it should be easy to demonstrate in 10 lines of code. If you can't reproduce it in 10 lines of code then you have a very large clue as to what's going on. Commented Aug 15, 2020 at 20:10

    Have you tried compiling one the examples supplied with the ESP8266 Arduino BSP (after adding #include <Arduino.h> to the top, of course) - maybe the eeprom_write one? If that works, you will be able to narrow it to something else in your code. Otherwise, you've probably got a corrupt install, or wrong platformio.ini configuration. You didn't add EEPROM to the lib_deps, did you? As you should be using the espressif8266 platform provided EEPROM library. Commented Aug 16, 2020 at 12:41
