Extra EEPROM

Hi,

I recently got a catalog from MOUSER Electronics and saw a bunch of EEPROMs in it. Very cheap, by the way.

I wonder if I can use them as an extra memory for my BASIC Stamp. Any ideas how???

Thanks.

    Well, if you want them for data-logging or other data as may be required then get I2C EEPROMs, BS2p units have I2CIN, I2COUT commands.· You can use I2C with BS2-IC, but there is a little more to it, as you have to program it to manage SDL & SCL.· Go to the Parallax site and look in the Nuts & VOlts archives (#s 79, 85, 115.)

    You can't use these EEPROMs to make for more program memory.

    This question pops up about every 2 days in the forum. Two popular choices are an I2C EEPROM such as the 24LC128 (16KB) . This is an 8 pin DIP and connection to a Basic Stamp is very simple with 2 pins (connected with two 4.7K pullup resistors), +5V and Ground. Refer to Nuts and Volts Column #115 (in the Parallax Documentation section) for sample programs www.parallax.com/detail.asp?product_id=602-00013

    If you need more than 32KB of storage, then CF/SD memory card with a serial interface is popular http://forums.parallax.com/showthread.php?p=589803

    Well, I want example code for how to load data into these EEPROMs.

    Thanks again.
