  • Hello,

    I'm trying to wire up and 24C02A EEPROM and read-write data on it.
    I'm using this datasheet : http://pdf.datasheetcatalog.com/datasheets/90/80419_DS.pdf

    I'm using SMT32F4 Discovery.

    I have vired as this

    EEPROM VCC -> Board 5V
    EEPROM CSS -> Board Ground
    EEPROM SCL -> Board SCL (B8)
    EEPROM SDA -> Board SDA (B9)

    Then I'm using this code;

    I2C1.setup({scl:B8,sda:B9});
    var eeprom=require("AT24").connect(I2C2, 8, 256, 1);
    console.log(eeprom.read(0x64,"Merhaba Dunya"));
    

    But I'm getting this error :

    
    Uncaught Error: I2C device not responding
     at line 1 col 50
    ...writeTo(this.i(a),this.a(a));return this.i2c.readFrom(this.i...
                                   ^
    in function "read" called from line 1 col 42
    console.log(eeprom.read(0,"Merhaba Dunya"));
                                              ^
    
    

    What I'm doing wrong?
