1287225SimpQuick Design Document for 1-wire bus 2287225Simp 3287225SimpIn new bus terms, 1-wire devices are attached to 1-wire buses (ow) 4287225Simpwhich are attached to a one wire bridge (owc). 5287225Simp 6287225SimpThe implementation follows the terminology used in the Maxim AN927 7287225SimpApplication note which defines the 1-wire bus as implemented for the 8287225SimpiButton product. This is considered to be the canonical definition of 9287225Simpthe 1-wire bus. This means that the 1-wire bridge will implement the 10287225Simpowll(9) interface. ow is one wire. ll is for Link Level to mirror the ISO 11287225Simpstack terminology used by AN927. The 1-wire bus is implemented in the ow(4) 12287225Simpdevice, which implements the own(9) interface (n for network, the layer 13287225Simpdescribed in the AN927). The presentation layer and above is the 14287225Simpresponsibility of the client device drivers to implement. 15287225Simp 16287225SimpClient drivers may only call the own(9) interface. The ow(4) driver 17287225Simpcalls the owll(9) interface and implements the own(9). 18287225Simp 19287225Simp$FreeBSD$ 20
