how did you measure your resistance then? if you have a 2wire resistive circuit then you would have to use solution D (which iam trying to fully understand at the momment). if indeed you have a two wire circuit, then you would need to ground of those wires..
I am a bit confused on how exactly you are measuring your circuit so its hard to tell what exactly you should be doing.....
the wire they sent me when buying the fusion brain has three wire. It hooks to the analogue header which has three pins( input, ground, 5v) so I hooked up only the input wire to the resistive wire and the FB input header. I was wondering if I need to hook up the ground to the car from the fusion brain since I use only that one input wire to the brain?Originally Posted by Urbanmindz
Yes.. you would have to hook up the ground to the ground of the car.. they recommend connecting it to the same ground where you grounded the power source ground.
If you do not ground the middle pin, you resistive wire will have nothing to force resistance against which is why you are getting wacky numbers...
try that out
okay, i will try it out be back in 10 min, also with the resistive wire we are measuring voltage right not ohms? I use the multimeter, i put the dail on DVC (20) AND came up with those values 3.9, 0.42, 1.12. 1.75, 2.30, 3.13 are these in voltage? if so I think there right
If you have the MM setup to 20V and those are the numbers you are getting then YES you are measuring voltage and NOT Resistance. according to the other thread i would have to message resistance rather than volts because my honda has a 2wire resistive circuit.
okay still nothing, This thing has got me ****ed! Does the program have to be open in order to work? or the configuator? when the program is open, input "0" changes when I hit the different buttons but just no actions. what do you think is wrong with it?
if you created the steering wheel control XML using configurator, then you will have a blank layout in fusion control center. The steering wheel program you created in configuration must be named 'FusionConfiguration.xml' and must be placed in this location 'C:\Program Files\Fusion Control Centre Uber MDX Edition\MDX' assuming you installed everything in the default location.
The Fusion Control Center must be running in order for the communication between the device and the logic you created.
okay i did all that, same problem I dont have a blankin fusion control center. the pages has the digital out puts and analogue inputs.
there could be many reasons as to why its not working. I am just going by what i have been reading in this tutorial and from speaking from other FB users. I personally have not had a chance to get something written for the FB but will lend as much help as i can from what i understand.
We should start from the very beginning. You already have your voltages and have all the info as to the values.. When you create the logic, you have to allow for some degree of difference in the value for fluxuation involtage (but not too much so that it could be misinterpreted as another keystoke) Ex. If you have two seperate buttons and one have a voltage of 3.5 and the other has a voltage of 4.5. the login for the first button (the two numbers you put in) should be something like 3 and 4 for the first button and then 4.1 to 5 for the second button.
Once you have all your logic built and everything is setup, make sure save the file as stated in the previous post i made and also VERIFY that you have the correct input.
make sure fusion control center is running.
If that doesnt work, then i would verify all the wiring and pin inputs. make sure you havent accidentally fried your PIC (like i did lol)
Also as a side note( as was recommended to me) use a single key press as your command. just to keep it simple under you get it working.
Start from the very beginning and follow the flow of the project (steering wheel, button press, voltage,FB Input,Logic, ETC) and make certain that you have not missed anything along the way..
Ok, custom audio guy, I am thouroughly confused as to what you are doing and what your thought process is...
Some things that need to be cleared up...
MDX is the program that talks to the Fusion Brain. If MDX is not running, your FB may as well not even be plugged in. If MDX is not running nothing will happen. MDX is what interprets what the FB is doing. The configurator is not needed at all. All it does is create an XML file easily. You could write it by hand if you want. So you run the configurator to get your XML file built, then leave it alone.
Also judging on these posts, I am unsure of your electrical knowledge. If you are measuring volts on your multimeter, it is in volts. If you are measuring ohms, then you are measuring resistance. When measuring resistance the car must be off. When measuring voltage the car must be on. The Fusion Brain reads voltages. Only voltages. So when you have a resistive network like a bunch of resistive buttons, you need to convert that into voltage through a voltage divider, which is what the options of A-D are of the tutorial.
Every different direction you can press on your steering wheel is a different button. So therefore, every direction you press that changes the resistance, changes the voltage through the divider. This is now what the FB needs to read. And it will only read it if MDX is open. Otherwise the FB will read the voltage and do nothing.
I want you to take a screenshot of the virtual brain with various buttons pressed.
Also post a (1) logic node of your XML file (since they are all the same with only differences in voltages).
Also post your values mapped to what buttons they should be.
What program are you sending this to?
