Copyright (c) 2007, Jim Studt (original old version - many contributors since)
 
The latest version of this library may be found at:
http://www.pjrc.com/teensy/td_libs_OneWire.html
 
Version 2.1:
Arduino 1.0 compatibility, Paul Stoffregen
Improve temperature example, Paul Stoffregen
DS250x_PROM example, Guillermo Lovato
PIC32 (chipKit) compatibility, Jason Dangel, dangel.jason AT gmail.com
Improvements from Glenn Trewitt:
- crc16() now works
- check_crc16() does all of calculation/checking work.
- Added read_bytes() and write_bytes(), to reduce tedious loops.
- Added ds2408 example.
Delete very old, out-of-date readme file (info is here)
 
Version 2.0: Modifications by Paul Stoffregen, January 2010:
http://www.pjrc.com/teensy/td_libs_OneWire.html
Search fix from Robin James
http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1238032295/27#27
Use direct optimized I/O in all cases
Disable interrupts during timing critical sections
(this solves many random communication errors)
Disable interrupts during read-modify-write I/O
Reduce RAM consumption by eliminating unnecessary
variables and trimming many to 8 bits
Optimize both crc8 - table version moved to flash
 
Modified to work with larger numbers of devices - avoids loop.
Tested in Arduino 11 alpha with 12 sensors.
26 Sept 2008 -- Robin James
http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1238032295/27#27
 
Updated to work with arduino-0008 and to include skip() as of
2007/07/06. --RJL20
 
Modified to calculate the 8-bit CRC directly, avoiding the need for
the 256-byte lookup table to be loaded in RAM. Tested in arduino-0010

DS250x add-only programmable memory reader w/SKIP ROM.
The DS250x is a 512/1024bit add-only PROM(you can add data but cannot change the old one) that's used mainly for device identification purposes
like serial number, mfgr data, unique identifiers, etc. It uses the Maxim 1-wire bus.
This sketch will use the SKIP ROM function that skips the 1-Wire search phase since we only have one device connected in the bus on digital pin 6.
If more than one device is connected to the bus, it will fail.
Sketch will not verify if device connected is from the DS250x family since the skip rom function effectively skips the family-id byte readout.
thus it is possible to run this sketch with any Maxim OneWire device in which case the command CRC will most likely fail.
Sketch will only read the first page of memory(32bits) starting from the lower address(0000h), if more than 1 device is present, then use the sketch with search functions.
Remember to put a 4.7K pullup resistor between pin 6 and +Vcc
To change the range or ammount of data to read, simply change the data array size, LSB/MSB addresses and for loop iterations
This example code is in the public domain and is provided AS-IS.
