Yes, the f_cpu define only controls timing calculations, which must
match the clock speed. If incorrectly configured, it won't be able to
talk on the 1wire net.

I see this in main:

// Clock is set via fuse

As long as your built it for 16MHz it should probably be
compatible (I'm
not familiar with any specific fuses the m328 might have).
Thus, f_cpu: 16000000
