TMSetup Overview Group

The TMSetup API function must be called before any other TMEX functions except the Session layer of API calls. No other TMEX API calls will operate correctly until the 1-Wire network has been called with this function. It is intended to be called once at the beginning of an application to initialize the 1-Wire network and verify the physical integrity of the 1-Wire network. Note that execution of this function will reset all the parts on the specified 1-Wire network.
