@ BigWumpus

Yes you are right. I saw (datasheet) that Page Write mode allows up to 32
bytes per writing cycle.
Now let's see how to 'cheat' the 24c64 !

@ Melanie

Thanks for the code.
Unfortunatly I receive a compiling error on line:
I2CWrite SDA,SCL,EEP,Address,[STR(CounterA)] = Bad Expression
I tried some small chances but no success.
I'm sorry I'm not a Pro and I still need your help.
Thanks
