Overview

Onewire uses SkipROM (broadcast) addressing to configure and run all DS18x2x temperature sensors on the 1-Wire bus conected to the LPUART2 interface. Next it waits for all sensors to finish the conversion. After that is searchs for individual sensors on the bus and communicates with them using conventional MatchROM (unicast) adressing mode, reads and and prints the mesured temperatures on the serial terimnal connected to the LPUART1 interface.

Starting conversion on many sensors at the same time requires much power so it may not work in parasite power bus configuration.
