hello, i have an arduino mini pro that i wish to add more flash memory to it. i was planing to use this EEPROM from ebay
http://www.ebay.com/itm/EEPROM-Shield-With-512K-For-Arduino-compatible-/170842959678?pt=LH_DefaultDomain_0&hash=item27c708af3e
does anyone know how to connect it to the arduino mini pro board?
also, is 256k bit = 32 kbyte? what i the conversion? thank you
also, is 256k bit = 32 kbyte? what i the conversion? thank you
yes as there are still 8 bits in one byte
i wish to add more flash memory to it.
i was planing to use this EEPROM
Which?
Just to be sure, the EEPROM does not allow you to extend the Arduino's flash memory, so you aren't going to be able to run larger programs.
It provides 32kB of external memory on the I2C bus. The connector at top right of the EBAY illustration is labelled SCL SDA VCC GND. SCL and SDA are the two signals for I2C.
The DIP switches labelled 1, 2 and 3 are connected to the address lines on the EEPROM and you would set these all to OFF unless you buy more of those devices in which case the switches allow you to select distinct I2C addresses for the extra EEPROMs.
I don't recognize the type of jack they've used - perhaps someone else here can put a name to it - but you would need the matching plug and then just wire the Arduino to the EEPROM board.

Thanks for the replies, flash memory and EEPROM is different? What I want to do is to be able to upload a larger sketch into my pro mini. How can I achieve this?

Replace the Pro Mini with an Arduino with a bigger flash capacity.
Adding EEPROM storage does not address the problem since your code is stored in the internal flash memory. If you are only looking for a small gain, consider whether you can optimise your sketch and/or libraries it uses to reduce the code size, or do away with the bootloader to free up a little flash storage.
You could write an interpreter that runs on the Arduino and read lines of code from an SD card.
// there exist sketches like this, I do not recall the name now
running code from an SD ....hm ok will check it out =) thanks!

Are you thinking of Bitlash?
