    Default Looking for the Hexa Adressing on a 24lc1025

    i have a blank here
    looking for the address to use I2C programming when pin 1 and pin 2 is tied to ground and pin 3 is tied to VCC.

    i am looking for the address in HEXA please!

    i know it's $A0 for lower block and $A8 for upper block (if my memory is correct!)

    Maybe my problem comes from the 4.7k, shoud i drop them to 2.7k?

    thanks

    You should use control address $A0 for write and $A1 for read (for lower), while (for upper) $A8 for write and $A9 for read.

    Read page 84 of PBP manual for the defines that suit your application.

    Cheers
