I have no successs to make BS2px working with 24LC256. I tried to use schematics from Nuts and Volts article, but it didn't work and then two other schematics from web, but it still doesn't work. I also tried to change the resistors from 4K7 to 10K. Does anyone have working schematic and code to share? Thanks!

Your pull-ups are out of spec -- use 4.7k (typical), no stiffer than 2.2k. And if you post your code we can sort out what's happening. I've used the 24LC256 will all of our BS2-family Stamps; a demo is attached. And let the WP pin float -- pulling it low protects the chip.
