emulate ds1990 ibutton

Hi,
Is it be possible to make copy of a working ibitton on a controller? so i will not need the iButton.

1 wire slave emulation

If so, what is the need for an iButton module?
If u r using a serial No. iButton, this will be an ID check system. Why do you need to replace the module? Why do you need this module in your embedded system? :?: :?:

sadat007,

this is a free ds1990 emulator project using 89c2051 mcu.

i am interested in any 1-wire slave emulation too. i’m trying to develop something similar to http://home.hetnet.nl/~thomas_7/1Wire/1-WireIOPort.html any help with ideas/code examples will be great!

Simple i want to make duplicate/copy so if original gone then i will have another, second it may help to break copy protection if i have one original.
