Thread: Steering Wheel Controls

All the digrams I used were in the AUDIO VISUAL, NAVIGATION & TELEPHONE SYSTEM section. I attached them below.

Looks similar enough... On your diagram it looks like youll just have to connect line 29 to 5v from the gameport, and lines 27 and 26 to the axis lines. After you do that just throw in any old resistor between 10 and 1000 ohms onto your axis lines with the diodes, I think I ended up using 270 ohms, then connect it to your gameport and create a 2 axis joystick in the XP control panel. After you have the joystick created goto properties for it, then click the settings tab, click calibrate follow the wizard along until you get to the axis calibration page. Click the display raw data check box and start pressing your steering wheel buttons, you should get different axis values when you do. You'll know you used the right resistor when the value when no buttons are pressed is not much greater then the values when a button is pressed. i.e. 20, 25, 30, 35 would be good values for three buttons and the no button depressed state where 20, 25, 30, 100 would mean the resistor your using is probably too big.

Will this program work with Win98?

You can't use the serial port. The signal is not digital (discrete voltage on, voltage off). Rather it is a variation in current that needs an analog to digital converter that is found in the joystick port. The only way you could use the serial port is if you first had a analog to digital converter circuit which would be far harder and more expensive to implement then just using the joystick port.

Theres no reason why it shouldn't, but I havent tested it in Win98.

CrazyOne01,

I am using something closer to 15 ft then to 6 ft. If I said 6 ft previously, I was lying .

Check the previous posts in this thread for how to test the thing. You want to look for resistance since it is the easiest to test for. Look at the diagram I posted eariler from the service manual of my car. It shows how to test the resistance of the steering wheel controls. You will need to do something similar.

According to the PAC SWI-X document, you should just need to use 1 joystick axis and connect it to the (Gray/Black) wire from your stereo and connect +5v to the (White/Green) wire. You will also need to fake the other axis so it can be detected by windows (You can't have a 1 axis joystick). To do this just connect the +5v line to the second axis line like shown here.
