    Re: Large number of flickering/ghost inputs on Master Cards

    Hello Jack

    Back from hols, just managed a few look ins whilst away. You are certainly welcome to see my setup, though I can explain it here and post piccies if you still need it. The MIP is wired as:-

    All power feed lines are run separately from othe cables
    All input/output breakout boards are connected via ribbon cables
    All input/outputs wires from the components to the breakout boards are loosely bundled together.
    All cables/wires are kept to the minimum ie the OC boards are mounted on the back of the MIP frame

    By all means try the new PIC for the expansion board. Unless OC are aware of other issues that are unknown generally, this will only cure the problem mentioned very early in the thread. That is sometimes was a mismatch between logical/physical state of switches when first powering up. This manifested itself by incorrectly showing the value of some switches at startup, however, when a switch in the affected bank changed state, then the software correctly read all switches in that bank and corrected the reported state.

    This gave rise to duplicate switches going high/low, when the values were finally synchronised. This anomaly only happened once, thereafter the logical/physical switches remain in sync.

    Regards

    David

    Re: Large number of flickering/ghost inputs on Master Cards

    Hi David,

    Thank you for your response. I assume the PIC chip will arrive within the next week.

    I think one thing I could try is reducing cable length, that is something I have not looked into at all yet. I would be very appreciative if you could post some pictures of your setup.

    Cheers,

    Jack

    Re: Large number of flickering/ghost inputs on Master Cards

    Hi Jack

    I cannot easily get a photo of the rear of the MIP wiring. However, I attach an earlier photo which show the principles, which have not changed. The photo does not show the ribbon cable connectors. Additionally, since the photo was taken an additional two mastercards have been stacked on top of the existing one, together with additional breakout boards also stacked on existing.
    There is no specific separation for inputs/outputs when the wires run to the actual components, however power lines are routed separately

    Re: Large number of flickering/ghost inputs on Master Cards

    Hi David,

    What you have posted there is actually very similar to the way I currently have mine wired up, hopefully I will get a picture to you tomorrow. The new PIC chip has arrived and I have installed it. No flickering so far, but I have only wired a very small portion of the cockpit up at the moment.

    Jack,
    if you now have it wired similar to Davids , that's a Very nice Reference that builders should strive for. Im sure you will have success if it all ends up like his.
