Hi all, i bought the MDSMC right when i bought the prop demo board and i was looking at using it for the prop it looks like it would be great on the prop demo board, i tried to use it on my bs2 and it just got hot and didnt work (did i break it? it didnt smell shorted out). so how can i make it work on the prop, i only know how to blink LED's so far and well im learning but slowly, i REALLY dont want $24 (more like $30 with shipping) to go to waste, so are there any objects in the OBEX that work for this? will it even work with the prop?

    The PDF states Logic Supply: 2.5 - 5.5 V (pg 2 of 12).
    Check your wiring, re-check it, then check it again.
    If you stuffed it, Uncle Ken will FedEx another to you right away.

    Post Edit -- That PDF is chock full of bold, red text. Junk like, "Warning", "Important Note" and the like which, apparently, they take seriously. Curious.

    I have used this motor controller with the prop and its pretty straight forward. I did manage to fry one of the motor controllers when the ground disconnected when power was connected.

    If you're just blinking LEDs you may want to wait a little while before tackling a motor controller. I don't know that there are an objects for this (doubt it), but that's okay as it's a very simple device.

    I've attached a shell program (which has code that could form an object) that should get you going -- once you're comfortable connecting the motor controller to the Propeller.

    What do you mean by what do I mean?
    You did everything right and nothing wrong. Got it.

    Post Edit -- I'm bad and you're good. That's why it got hot and "doesn't work." Why should it be any different with a "Prop"?
