ibutton pic

Hi, anyone can teach me a circuit to read an iButton(ex. DS1990A) with PIC(ex. 16F873).. A simple project and the code writing in C Language(not in Assmbl).
Thanks

pic ibutton

What do you mean?
I have a PIC and an iButton. Then, I want to program my PIC (in C Language) so that can read the serial in the iButton. Could you teach me?
Thanks

iButton is one of 1-Wire Products from maxim.
You can check h++p://www.ibutton.com for further.
I think this button is very interesting. I want to combine it with PIC

Most of C compilers for pic have example for 1_wire or for ds1990
the simplest is Mikroelektronika
see project for Basic
**broken link removed**
and try MicroC Example
