I'm working on the ds1wm support. Just got example code from Maxim. How about
basing you modifications from that.

the bus master and slave functions are encapsulated easily. Since we
support so many different devices, the level of abstraction is very precise.

Dear owfs developers,
I'm currently exploring options of adding custom hardware-based onewire master
chip support into owfs. Could you explain which parts of the software stack of
owfs would need to be extended/altered in order to add new bus master support
