eeprom

Hi,

I have a problem handling in eeprom AT24c1024

While handling a vlaue less than 127 of a byte
There is no problem in handling reading and writing.

While handling a value more than 127 of a byte
The response while reading eeprom is FF.

Can some one suggest me what could be the problem..

Thank you...

Re: eeprom

may be the variable you are using is char
so by default it is signed char(-128 to +127)

so change it to unsigned char(0 to 255)
