There is no good part that can replace it. >=20 >=20 > PIC 10F ... ? >=20 > R It may come to that but it is not that simple. Each chip needs to be progra= mmed=20 and each has to have a unique 1-wire ID. In some equipment there are 4 DS24= 09s. Furthermore it has to support most of the DS2409 functions such as smart=20 main/aux on, rom search, automatic and manual ctrl output, short circuit=20 detection... /Ruben =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D Ruben J=F6nsson AB Liros Electronic Box 9124, 200 39 Malm=F6, Sweden TEL INT +46 40142078 FAX INT +46 40947388 ruben@pp.sbbs.se =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
