If your embedded design uses the w1 kernel module to control the gpio pin,
owfs can use it as a generic 1-wire bus master and allow all the functions
of the DS2770 to be used.
Basically you start the program with the --w1 argument to use w1. You need
to be root to access the kernel module (and communicate via netlink).
