Writing and reading to a 24LC1025

[skimask]

I am developing a weather station logging system uses a 16F877 and should write 16 bytes of daily data to a 24LC512 EEPROM. Using I2C, I have a DS1307 (which works fine) connected on the same bus as the 24LC512. However, I cannot write or read succesfully to the EEPROM at all. the 3 address pins on the 512 are grounded. After trying unsuccessfully to write & read in page mode, I went back to the "Really simple" example in the PBP handbook, which I still cant get to work - instead of reading a 6 back, I get 255

Do a search here on the site for 24LC1025. There was another person awhile back had similar problems with the larger I2C eeproms, got it working with the advice in that thread, something about splitting the address into two seperate bytes in the command line, not really sure.
