Library "OW_Utilities" provides the basic one-wire search ROM and search ALARM routines  e.g. for the DS1820, the DS18S20 and the DS18B20 digital tempsensors.

The interface: var ROM_NO: array[8] of byte;


// the rom code found (if any) will be stored in this array function OW_Search_First_ROM(var Port_: byte; Bit_: byte): boolean;   
// Search for the first ROM number. Returns true of one is found. In this case the found number is in "ROM_NO".

function OW_Search_First_Alarm(var Port_: byte; Bit_: byte): boolean;   
// Search for the first ROM number of a device in alarm. Returns true of one is found. In this case the found number is in "ROM_NO".

function OW_Search_Next(var Port_: byte; Bit_: byte): boolean;
// Search for the next Rom number or the next Rom number of a device in alarm, depending on which "search_first" was used before.
// Returns true of one is found. In this case the found number is in "ROM_NO".

Library for making an USB host capable of reading and writing sectors from/to USB memory sticks (&quot;USB drives&quot; or &quot;pen drives&quot;).To read/write actual files from/to the USB memory stick you need still e.g. a Fat16 or Fat32 library (see example).
