The Raw 1-Wire library provides access to the ROM's very basic 1-Wire functionality. It allows applications to iterate through devices on the 1-Wire bus using ow_first() and ow_next() functions, get the currently selected device's ID, and communicate with devices using the ow_byte() function.
The 1-Wire sample application searches the 1-Wire bus for a device. If a 2502 is found, its memory is displayed.
