    now i'm just waiting for a complete kit from dejan....

    got an idea... is it possible to blend a picture over the feed from the cam? could be very usefull so that you could draw guidelines that shows where the car would go, could imagine this would be very helpfull on parking lots where the spaces are just painted and there is nothing to messure distance against

    Hi Robby,

    Just starting to put together my carputer and this is awesome !

    I have an 8 sensor (4 front + 4 rear) parking assist unit in my car and it seems to be a similar model to your first system in the first post of this thread going by the case markings. It is a wired display and similar to the following unit on ebay 8-sensor parking display.

    My question is...
    If I do a scope trace of the signals it uses, could you do a custom PIC for me which does the full front+rear in the one interface ?

    Will this one work with PDC

    The parking sensory avaialble here locally have 6 wire connection the the display unit. 2 wires carry power and ground and I am not sure what the rest of the 4 wires carry. The display unit is LED type and has almost same chips and construction given in the first few posts except the RF module. Any clue if this can work with PDC. I am attaching the picture of the controller board and the three main ic's are:
    IC3: NXP HEF4052BT
    IC4: ON Semi 14013BG
    IC5: TI TL084C

    The display unit is based on Atmel AT 89C2051

    Could someone please clarify how front & rear PDC is done.
    - Do i need 2x 4 sensor kits, or 1x 8 sensor?
    - Do i need 2x the USB-PDC boards, or one?
    TIA HoSS

    You are right.
    You need:
    2x USB PDC kit with diferent version of PIC
    2x 4sensor kits one you must have connected by wire

    Sorry I can't provide you only PIC. Why? Because I have only 2 and Robby will not be back until december and then I can't sell my boards, which I have at home...

    Best regards, _Dejan_

    My understanding is 2 x USB PDC boards (one has a slightly different PIC software). Each board runs 4 sensors.

    ** Edit ** Dejan beat me to it !
