The super 100% rear view system!

HiJackZX1 · 12-20-2008, 11:40 AM

After debating on wether to use the FB in my install, in the end I decided not to use it to have it take over alot of functions of the car. When the car started, I had to be able to simply go and do my stuff. I guess deep down inside I wanted the FB, so I have found a new purpose for it, but I want to ask if it is doable first.

I have a complex rear system, it is controlled by a Digital Quad Proccessor, which is used for security cameras to show multiple cams on 1 screen. I know I will be breaking the law, but I have decided to x-out my side mirrors and have only cameras. Currently when I turn the car on, I have a monostable switch that turns the DQP from it default 4 screen view, to a 3 screen view, which shows left and right sides and rear. Here is where the FB comes in. When I go to turn left and use my turn signal, I would like the FB to tell the DQP to go to camera 2, which is the left camera. Once I shut off the turn signal, the DQP goes back to 3 screen mode. Same thing with right side. I know the FB is programmable, so will I need the PC to be on to do this? I do not really want to control it at all through the PC, if anything it will be a process that runs in the background. Please give me pointers on what I can do to acheive this, or if I need a FB at all.

From what little I know about the FB, your computer needs to be running for it to work. It isn't a programmable device in the sense that it operates independently whether your PC is on or off.

Ok thats cool.......... but what do I need to animate everything. like how would I connect the FB.

The PC would need to be on as always. But MDX can run in background and automate everything of course.

ARGGGGGGGGGGGGG but you guys arent explaining how I do it physically. I was thinking of intergrating the remote into FB because it has a option to go straight to a specific camera via a button. The DQP itself doesnt have that option, instead I have to hit one button and cycle through the screens. So the remote is the best bet. I assume that the outputs on the FB send power through them, So I would have to use relays on each button. Can the FB do a single pulse, rather then a constant signal? I ask because that is all that is needed. I guess I would connect the flasher relay from the blinker system to the inputs of the FB. Then when the FB detects the right or left pulses from the blinkers, it sends one single pulse to a relay that then switches it to left or right. Here is were I am curious also. Once the FB no longer detects a pulse from the blinkers, can it send a pulse on its own to default the DQP back into 3 screen mode?

Of course. This is one of the most basic uses of the Fusion Brain.

The how is:

Connect relay to output.... Done.

In software either do a toggle which can be configured all through the GUI of the Configurator, or you can use the pulse feature which you will have to edit the xml file manually (as of 21/12/08).

the following 2 can be used, depends on how and when you want the pulse:

Code:

<iochannel id="Digital Output 1" port="1" brain="My Fusion Brain 0" type="digital_output">
        <defaults defaultstate="off"></defaults>
        <options>
          <sequence period="1000" iterations="1">
            <value order="0" state="off"></value>
            <value order="1" state="on"></value>
          </sequence>
        </options>
      </iochannel>

      <iochannel id="Digital Output 2" port="2" brain="My Fusion Brain 0" type="digital_output">
        <defaults defaultstate="off"></defaults>
        <options>
          <relatively_timed_sequence iterations="1">
            <value time="0" state="off"></value>
            <value time="1000" state="on"></value>
          </relatively_timed_sequence>
        </options>
      </iochannel>

The first one changes the sequence every 1000ms. So immediately it turns it on. Next cycle 1000ms later, it turns it off. Repeats 1 time, so it doesnt repeat until started again.

The second one changes the output depending on the time. So at 0ms (instantly) it turns it on. Then it waits 1000ms and turns it off. Then repeats 1 time, so it doesnt repeat until started again.

OK, that kinda makes sense. Basically the trigger would be the left and right blinkers, but because they turn off and on, would that be an issue? If I am understanding, I would have the trigger be the blinker, then the software would see the pulses from the blinker and tell it to send a single pulse to the relay. Then after a certain amount of inactivity the FB will send a pulse to send the DQP to its 3 way screen.

2k1Toaster · 12-21-2008, 04:13 AM

Again, that is just software.

OK, so I guess i'll go head and buy it then. Is there someone to help me with the software aspect? Like write something up for me?

Why not get your source signal from the turn signal switch on the steering column? That won't "blink" and won't have the problem of getting confused if you have your hazards on.

I was just thinking about that. i will most likely connect it to that. On a side note, a user emailed me a device that is made to do just what i want to do with the FB. It connects 3 sources, so what i would do is connect the DQP to the rear source, that would show me all 3 screens. Then I connect left and right to the device. When i use my blinker it switches to left or right. Thing is, it is $51.00, but because its in Canada, i also have to pay $19.00 for shipping and $27.00 for a costums tax.
