Dinsmore1490 Compass

Hello,

I'm trying to use a Dismore 1490 Compass with my BS2. I'm a noob at this and
have only done a few projects. The data sheet for this compass says that its
four outputs (one for each direction) sinks 20 mA. So now i'm confused as to
how this output can register to an input pin on my BS2. Thanks!!


Phil

    Phil -

    Here is one sample program you may want to look at:

    Phil -

    My apologies. There is a driver program that comes from a separate PIC. I
    hadn't
    initially noticed that. Here is the whole web page for your perusal, however.
    http://www.frii.com/~dlc/robotics/projects/botproj.htm

    Sorry !

    Regards,

    Bruce Bates

    Hi Phil -

    This may prove to be a more helpful resource than what I posted before:
