I2C Smart Card memory

[pedja089]

Try to scan all addresses.
Something like this

FOR i = 0 TO 255
    Adr VAR BYTE/WORD depending on memory size expected
    ADR=10
    I2CWRITE datapin,clock,i,Adr,[123]
    PAUSE 10
    TestByte=0
    I2CREAD datapin,clock,i,Adr,[TestByte]
    IF TestByte=123 THEN
        Write 0,i
        END
    ENDIF
NEXT i

And after few seconds read eeprom of PIC, Or you can use serout to show address on PC, etc...
I guess it should be $A0.
Can you post picture of smart card, so someone can recognize it and find internal schematic?
