Arduino Library – OneWire

OneWire Library
OneWire lets you access 1-wire devices made by Maxim/Dallas, such as temperature sensors and ibutton secure memory. For temperature sensors, the DallasTemperature library can be used in conjunction with this library.
Hardware Requirements
OneWire requires a single 4.7K pullup resistor, connected between the pin and +5 volts. Then just connect each 1-wire device to the pin and ground. Some 1-wire devices can also connect to power, or get their power from the signal wire. Please refer to the specifications for the 1-wire devices you are using.
History & Credits
Jim Studt wrote OneWire in 2007, originally based on code by Derek Yerger.
Tom Pollard added CRC code which eliminated the need for a 256 byte array (in RAM).
“RJL20” added the skip function.
Robin James rewrote the search function.
Paul Stoffregen rewrote the I/O routines for interrupt safety, replaced search with Robin James’s code, applied several small optimizations, and started calling it “version 2.0” to distinguish from the many buggy copies online.

v2.3.3 No actual code changes, just updated comments about where to request support (hint, always use forums, never private email, and only github issue for actual code issues) v2.3.2 Add support for more boards: Arduino Zero Arduino 101 / Intel Curie RedBearLab nRF51822 (untested) Add conditional search mode v2.3.1 Support for more boards v2.3 Search bug fix (Love Nystrom) |
