Method reset_search

Arduino/libraries/OneWire/OneWire.cpp:325–335

You need to use this function to start a search again from the beginning. You do not need to do it for the first search, though you could.

// You do not need to do it for the first search, though you could.
//
void OneWire::reset_search()
{
  // reset the search state
  LastDiscrepancy = 0;
  LastDeviceFlag = FALSE;
  LastFamilyDiscrepancy = 0;
  for(int i = 7; ; i--) {
    ROM_NO[i] = 0;
    if ( i == 0) break;
  }
}

// Setup the search to find the device type 'family_code' on the next call
// to search(*newAddr) if it is present.
