I want to create a system that can copy eeprom data from a 24lc256, store the data to the mbed, and hold about 4 copies of the data. 256k * 4 = 1024k

Is the best way to store the data with an external FLASH IC?

You can simply copy the data from the EEPROM to a text/data file in the MBED its self,

It should be quite straight forward.

I have copied the data with the internal storage but I want a more portable solution. Or maybe I just copy the mbed design and use the same file storage IC. I assume its off the ucontroller?

Not quite sure what you really want to do,

Do you just want to read out the contents of the EEPROM, and save them as a text file,

Or - do you wish to selectively re-program EEPROM's ??

The flash IC is connected to the interface IC, and not the LPC1768 itself. There are however a bunch of libraries for different flash ICs.

I would use SD Card,

big advantage - portability of content.

selectively re-program EEPROM's. One EEPROM really. A device I am using configs its self upon startup from an eeprom @ 0xA0, the device acts as the Master on the I2C bus. I want to be able to reprogram the EEPROM after the device boots. I will have a simple UI to select which EEPROM 'file' to load, also an option to read and record the EEPROM data. I think SD card is the way to go. Cheap and portable. I was exploring IC's as an alternative.

Hi guys, maybe do you have a code that guide me to copy data to eeprom?
