SPI Filesystem on 64K EEPROM???

Other Hardware Storage
1

Hello I am trying to connect the following EEPROM to an arduino uno, my intention is to be able to load a file to the EEPROM via USB and have the arduino load parameters from the file on startup. I have wired the EEPROM according to this tutorial. Is there a library I can use to make this work?

Thanks Rob

I cannot find a specific library for this chip but maybe someone else's SPI EEPROM library will work with little or no modifications.

Thanks Riva, is there an EEPROM library that you are familiar with?

Have a look at this page: http://arduino.cc/en/Tutorial/SPIEEPROM
The SPI commands listed there are the same as those for your chip so the code should for you as well.

Thanks for the link, when I copy and paste the code from the tutorial and try to compile it I get the following error

510×626 52.3 KB

Change each occurrence of
Serial.print('\n',BYTE);

to

Serial.println("");

Awesome thanks Pete, I was able to get it to work after altering the code as you specified. So with this I have proven to myself that I can interface with the external EEPROM through the copy and paste of a program. The project needs to be able to accept a small config file loaded by the user, and I believe this would require storage which is separate from the Atmega328P to prevent any alterations to the data stored on the internal EEPROM after the device is calibrated, Thus why I am trying to setup this external EEPROM. Before going any further is this the correct method or is there a much simpler way that I am un aware of?
