DSMLINK mini-FAQ (contributions by Grant, Tom and Dave)

 

Where the heck do I find the DSMLink Palm interface user manual (a.k.a. PalmLink)?

How do I use the dsmlink ECU simulator, a.k.a. FakeECU?

How do I compile the source code?

I have the DSMLink in my car, now how do I make it faster?

How do I log/display LTFT (or other value)?

Q)    Where do I find the user manual for the DSMLink palm interface?

A)

http://206.124.12.138/dsmlink.html

 

Q)    How do I use the DSMLink ECU simulator, a.k.a. FakeECU:

A)

1)Run the following commands in your DSMLink source directory:

Source:> javac DSMLink.java

Source:> javac car/FakeECU.java

Source:> java car.FakeECU 7000

 

2)Make sure there is a sample log file called FakeECU.dat in the source directory for the simulator to use.

 

If you want to test some things out you may want the DSMLink fake ECU running at the same time as running the DSMLink Client on the same machine. The following will get the DSMLink client to run, once it is compiled. Assume you have the FakeECU running on port 7000 as the FAQ currently demonstrates.

 

3) Update the file dsmlink.prefs (in the DSMLink install directory) with the line:

//portID=COM6

//Comment out the current portID (donít forget to change this back when you want to connect to the car)

portID=7000

 

4) Launch the dsmlink client application

 

Q)    How do I compile the source code?

A)

1)      Download and install JDK 1.3.1 or higher from sun: http://java.sun.com/j2se/1.3/download.html

 

2)      If your DSMLink source is in c:\DSMLink, and your java install is the default (c:\jdk1.3.1_02) then you should add these lines to your environment batch file:

set CLASSPATH=c:\jdk1.3.1_02;c:\DSMLink;c:\jdk1.3.1_02\lib\ext\comm.jar;.

set PATH=c:\jdk1.3.1_02\bin;%PATH%

 

3)      Download and unzip java comm package from http://java.sun.com/products/javacomm/

1.      Extract comm.api from the unzipped directory to your java/lib directory

2.      Add c:\jdk1.3.1_06\lib\comm.jar (or path to your comm.jar file) to your CLASSPATH

 

3)      go to your dsmlink source directory (c:\dsmlink) and type ďjavac DSMlink.javaĒ

 

Q) I have the DSMLink in my car, now how do I make it faster?

A)

Look at Tomís Tuning Tutorial, located here:††††††††††

http://groups.yahoo.com/group/dsmlink/files/Tuning%20a%202G%20DSM%20ECU.doc

 

Q) How do I log/display LTFT (or other value)?

A)

To add things like the LTFTs, while you have DSMLink talking to the ECU (but no log currently displayed), select ECU/Stream data and add the items you want.DSMLink sends these additional selections to the ECU and the ECU will then send these in addition to the default list.The ECU saves these additional selections until you change them.You can then use data/values to choose which will be displayed.

 

Tips from Grant:

set classpath=classes;lib\commapi\comm.jar

java -Djava.library.path=lib\commapi DSMLink

 

The first line lets the java runtime see the com api and your class

files. The second line tells the java runtime where the windows

win32com.dll is located (assuming you put it in a lib folder under

commapi).

 

I put the dos commands in a batch files located in the bin directory

off the root of my DSMLink project so I don't have to re-type this

stuff:

 

dsmlink/bin - batch files

dsmlink/src - source code

dsmlink/lib - library files

dsmlink/classes - where the compiler drops the class files
