The 1-Wire API for Java contains classes and interfaces that enable rapid development of 1-Wire applications in the Java language on a variety of platforms. All desktop 1-Wire adapters are supported on the Win32 platform through a native driver. TINI has its own native 1-Wire ports. The book is published by Addison-Wesley is available for purchase at most book retailers. The list that follows highlights the most significant additions. The classes in this package implement an entirely new architecture for SHA applications.

Besides decoupling the protocol for SHA transactions from t he user token’s support classes, the new architecture greatly simplifies the process of adding new user tokens as well as new types of transactions. Two sample transactions included with the package are a “money” debit application with both signed and unsigned account data. The use of a hardware coprocessor DSS is now optional and can be replaced by a software-simulated coprocessor.

Using XML, devices can be grouped together into clusters and can be dealt with by applications based on their purpose, not just their device type. See the documentation included with the demo applications for details on the XML 1-Wire tagging format.

The 1-Wire File Structure classes com. A demo application was added to demonstrate its use. The classes in package com. These classes are not required for Java Powered iButton development.

See the examples distributed with the iB-IDE for examples on how to use these classes. Uncompress the kit file into a directory on your development system. The development system must be able to run the javac compiler. See your JDK or equivalent for minimum system requirements. If you have a previous version of this file, make sure it is replaced or removed.

This kit supports firmware version 1. It can be found here: Install the standard drivers from here: The latest version 3. Info on rxtx can be found here: The driver has a default mode on Solaris that forces it into single bit at a time mode. Of these baud rates, the fastest baud rate observed on some Solaris machines is Each example has the following support files and directories:.

Adtasheet that this application is almost identical to the example of the same name in ds503 1-Wire kits. Humidity Find and read all 1-Wire devices that implement the HumidityContainer interface and display the current humidity. Read, write, format and display the file system on a 1-Wire memory device. This application does not implement sub-branches but has been optimized and is very fast.

SwitchDemo Get the status and set the latches on any 1-Wire switch. Thermochron DS temperature gathering demo consisting of two applications. All of the adapters can be enumerated or a particular or the default adapter can be retrieved enumerateAllAdaptersgetAdapterand getDefaultAdapter. Here is a brief list of the operations needed to access and use the 1-Wire network. Get an adapter instance 2. Get exclusive use of the 1-Wire network 3.

Find a 1-Wire device 4. End exclusive use of the 1-wire network 6. Free the port when ending application. Dstasheet these properties cannot be found then a platform dependent “Smart default” is used.

To allow for multi-thread access to the 1-Wire network, a pair of methods are provided in the adapter class to give exclusive access. It is recommended that this pair wrap any access to the 1-Wire network. This family code is used to provide the appropriate container and can also be used to limit the search of the 1-Wire Network to one or more device types.

For example the following code fragment will search for devices with 0x10 family code.

DS Datasheet, PDF – Alldatasheet

Note that there are other search methods findFirstDevice and findNextDevice that do not automatically create a container and may be quicker if speed is essential.

Also see these other methods for search options: OneWireContainer is then used by th e application to manipulate the device. The adapter will automatically provide the correct container. If the family code is unknown then the adapter will provide the super-class generic container. DS 01 1-Wire Address only. DS 02 Secure memory device. DS18S20 10 Temperature and alarm trips. DS 21 Thermochron temperature logger.

DS 27 Real-time-clock with interrupt. A memory bank is a section of memory on a 1-Wire device that has specific properties. For example the 1-Wire Network Address of a device is a read-on ly bank of 8 bytes. This technique is used to get a handle on the diverse types of memory that comprise 1-Wire devices.

There are three interfaces that the memory bank may implement. These interfaces are hierarchical:. Any 1-Wire devices that contain memory can also use the 1-Wire File system.

The following classes in the com. OWFile — Like java.

The specification for the 1-Wire file system can be found in Application Note A 1-Wire Sensor is a device that can make a reading or change the state of something physical such as a DS switch. Typically the operations of 1-Wire Sensors is memory mapped so writing to a particular location causes the state to change. Each Sensor interface is derived from a super-interface com.

OneWireSensor that contain just two methods: The read returns a byte datsaheet and the write takes a byte array. The byte array is the state of the device. So a OneWireSensor operation is:. The following is a list of the interfaces and a brief description. Note that the container list above indicates the interfaces used. This is a microprocessor in an iButton package that has a Java Virtual Machine that can run Java applets.

These applets typically perform highly secure cryptographic operations. See this web page for more information: Communicating with a device in Overdrive speed just requires that you call the setSpeed int,booleandefined in OneWireContainer.

The boolean value indicates whether or not it is okay for the device to fall back to a slower speed if communication fails. The DSPortAdapter object also has a set Speed int method, but it is not advisable to call this one directly.

Instead, allowing the container itself to be the only entity who manipulates the DSPortAdapter’s state, you can be assured that the two will not be out of sync. Also, if you’re in a situation where you have devices on the 1-Wire Net who support Overdrive and devices that don’t, it’s important to remember that regular speed communication will cause devices in Overdrive mode to revert to regular speed. The opposite situation Overdrive communication on the same network with devices in regular speed is harmless.

However this can be a slow procedure on some platforms so it should not be called indiscriminately. All of the Java source in this kit is provided so if the documentation is not clear or is non-existent, look in the source.

See this page for more information. Since its memory resources are limited, only the containers and necessary classes needed for the application are transferred to TINI. Dallas Semiconductor has selected the least restrictive license it could find to apply to the Java source code in this kit. It is based almost word for word on the Xfree86 license http: It basically says you can do anything you want with this code.

If you distribute the source then just leave the license blurb at the top of the source files.

These settings were selected by taking the recommendations for a meter and meter 1-Wire cable in Application Note The datasheet for the DSB can be found here: Find all 1-Wire devices and iButtons on all available 1-Wire xatasheet. Find and read all 1-Wire devices that implement the HumidityContainer interface and display the current humidity.
