Tutorial - Air Ride Suspension
Hardware

So far, the only sensors we have data for are the Dakota Digital sensors.

http://www.dakotadigital.com/index.c...rod/prd124.htm

Code:
150psi, 1/8-27 NPT

PSI		R typical	R max		R min
0		10		13		5
14.5		31		35		27
29		52		56		48
43.5		70		74		66
58		88		92		84
72.5		106		111		101
87		124		129		119
101.5		140		150		130
116		155		170		145
130.5		170		185		155
145		184		214		154

Maximum 435 psi for 2 seconds only.
Operating Temperature:  -13F - +212F (to +248F max. 1 hour) on
connecting thread.



Then, all you need to do is hook the air ride sensor up like so, knowing that the body of the sensor is grounded.

As far as software, Nick will be along shortly to do that bit.

To Use above code

Insert this into your logic area (between "<logic>...</logic>". You obviously need to replace the analogue id with the id you declare in the io section "<io>...</io>". And you must reference the above code in a seperate function file in the "<require></require>" area.

**Note: The "..." in the following code mean that there can/will be other non-related items between the code sections. Fusion Control Centre Uber Edition doesn't care about the order. It only cares about heirarchy. Meaning "<iochannel>...</iochannel>" must occur between the opening "<io>" and closing "</io>" tags. If it is not in there, FCC will skip right over it, and that input channel will never be created.

Code:
...
<require>
...
    <!-- Begin Function Instances -->
    <function file="content\config\AirRidePressureSensorModule" id="AirPressureSensor"></function>
    <!-- End Function Instances -->
...
</require>
...

...
<io>
...
  <!-- Begin Analogue Input Instances -->
      <iochannel id="RF Air" port="0" brain="TucciBrain2" type="analogue_input">
        <options history="10" auto_average="true"></options>
      </iochannel>
      <iochannel id="LR Air" port="1" brain="TucciBrain2" type="analogue_input">
        <options history="10" auto_average="true"></options>
      </iochannel>
      <iochannel id="LF Air" port="2" brain="TucciBrain2" type="analogue_input">
        <options history="10" auto_average="true"></options>
      </iochannel>
      <iochannel id="RR Air" port="3" brain="TucciBrain2" type="analogue_input">
        <options history="10" auto_average="true"></options>
      </iochannel>
  <!-- End Analogue Input Instances -->
...
  </io>
...

...
<logic>
...
  <!-- Begin Variable Declarations -->
    <all_variables>
      <variable name="Variable_LeftFrontAir">50.0</variable>
      <variable name="Variable_LeftRearAir">50.0</variable>
      <variable name="Variable_RightFrontAir">50.0</variable>
      <variable name="Variable_RightRearAir">50.0</variable>

2k1toaster,
In what program does this have to be written in?
and
I see that this is an XML, Will I need to open this in a webpage? can I incorporate it to Streetdeck some how?
Where is the <io></IO> section?

You can write this is any program that supports either xml (Dreamweaver, Word, Free XML Editors scattered around google), or in any plain text editor (Notepad and free ones too, just save the file as *.xml not *.txt).

You do not need or have to open it in a web browser. You can if you want to view the xml if you have no editor (which if you run windows you do, Start-->Programs-->Accessories-->NotePad).

This code is only understandable by Fusion Control Centre Uber Edition (FCC). Currently, the latest release of Uber is MDX (Managed DirectX) and downloadable as shown here: http://www.mp3car.com/vbulletin/docu...rsion-mdx.html

To incorporate into StreetDeck, currently you must embed FCC into Streetdeck as an external program. I have been working on a COM object (I promise I have been, but it is slow going now because of how Vista changed COM objects) which will allow the Fusion Brain to be controlled via a plugin (DigitalMod I believe is the SD term). This COM functionality is not available yet, but I hope it will be before summer. Until then, embedding the program works well. You may have to run SD in "testmode" to enable usage while moving.

I don't have the car with me to test this. I'll get the car back in about 2 weeks.
