I've written a few C functions for dealing with external page write eeprom. I have these functions: WriteEepFirstByte(address, data) // sets up address, sends data, increments static address counter, leaves /CS low WriteEepNextByte(data) // sends data, increments static address counter, does page write if incremented to new page, leaves /CS low WriteEepLastByte(data) // sends data, does page write, releases /CS WriteEepOnlyByte(address, data) // writes the specified byte to the specified address.
