As Jan points out, the official source of 1-wire numbers is Maxim. In
general they reserve 0x00 to 0x80 and use the upper half of the family code
space for "special runs" and 3-rd party.
Some people have just chosen a number on their own -- Luis Swart took 0xFF
years ago and even proposed splitting the range for other 3rd party
developers.
Hobby Boards bought EE and EF and has "type" fields within the device to
identify different slaves.
EDS purchased and uses 7E similarly.
So if this slave is only for your own use, choose any number. If you want a
commercial product, investigate purchasing a family code.
In any case, think about the architecture. At the very least, there should
be a consistently accessed type and version field that can be read to allow
you to offer new versions and different types. i.e. OWFS will see your
family code, read the always available type field and then know which
special techniques are needed.
