• TINI - Tiny Internet Interface - Very cool little fellows these, Java VM, TCP/IP, 1-Wire, ethernet, serial, CAN, etc. all on a 72 pin SIMM form factor. I'm finding my way around it and posting anything I think might be useful here.

    Building TINI Binaries
     Once you have compiled Java classes from their source, they need to be converted to TINI's binary format before they can be used. Dallas provide two utilities for creating binaries - TINIConvertor and BuildDependancy.
    These are well documented in the files Building_Applications.txt and BuildDependency_README.txt included in the TINI distribution.

    Basically TINIConvertor is used to build the TINI binary and can be used directly if your program does not depend on any classes that are not included in the standard TINI API.

    Make sure that tini.jar from the TINI SDK is in your class path and then the syntax is:
    java TINIConvertor -f -o -d /path/to/tini.db If your program depends on classes that do not make up part of the TINI API, such as OneWire containers then BuildDependency must be used. This builds in extra dependencies before calling TINIConvertor to build the binary.

    Again with tini.jar in the classpath, the syntax is:
    java BuildDependency -f -o -d /path/to/tini.db -add -x -p
    Where dependency list is a colon seperated list of dependencies to include, e.g. OneWireContainer04;OneWireContainer21 Here are a few shell scripts to keep the typing to a minimum…

    However, a far better way of automating the build process of TINI applications is to use TiniAnt, which is an extention to Apache Ant the cross platform build tool. TiniAnt adds a new task type, to ant that really takes the pain out of building large TINI projects with complex dependencies.

    1-Wire Example Code

    The source for some sample servlets using the 1-Wire API to control and monitor several devices can be downloaded below. These work fine on TINI in conjunction with TINIHttpServer, but note that the code has not been optimised for TINI's JVM. They will also work on other platforms that support Java and 1-Wire such as a PC equipped with a DS9097U serial to 1-wire adapter and running a suitable servlet container such as Jakarta Tomcat.


    To build the servlets into TINIHttpServer, the build.properties file in the source distribution must be modified. Specifically, alter the servlet.src property to reflct the locations of the servlet source and the onewire.deps property to include any dependencies. I found it easier to alter onewire.deps to a colon separated list of dependencies rather than using THS_ALL ro THS_MIN as this gives more control as to what is compiled in.

    Systronix do a nice line in TINI accessories, and also a bunch of other cool embedded Java stuff. The 8x1 Wire I/O board is a good for getting started with 1-Wire as it has four DS2406s to give 8 bidirectional I/O ports. It also has a push switches, LEDs and a buzzer jumpered to the I/O ports.

    The source for a little quick and dirty program to test the 2406s on the Systronix board is here
