Either there is still a serious language barrier here or you're not getting what we're trying to say... In either case, I wish I spoke whatever language you speak so we could get this all straightened out a lot faster...

I use this display NOW , and scroll a simple text , but a long text , what is writing in a 24FC512 menory . It has pins 1,2,3,4 and 7 to ground .
And is it working the way you want it to work?

What doing this ?
Shouldn't have to use 2 different 'codes' for reading and writing to an I2C eeprom. PBP handles the Read/Write bit (bit0 in the 'code') for you. Should only need to use $A0 when addressing a standard 24xxxxx serial eeprom.

I use a long text....with caps.letters only (you can see this in my programe)
Are you storing the entire string, along with the temperature data in the eeprom or just the temperature?

Look back in message , I must to use only this formula , only one .
That may be so, but to store a temperature, with a whole part and a fractional part, along with any other characters, you are going to need more than one byte of storage and will need more than one I2CWRITE command...
