Thread: Can I replace ARbotix with Arduino Mega 2560?

  1. Can I replace ARbotix with Arduino Mega 2560?

    This is my second ARbotix board which works fine for some days then it will become impossible to upload the code because of the content mismatch error. I just want to get rid of Arbotix-M. Can I replace it with ARduino MEga 2560?

    I'm making the PhantomR

    Your helpful suggestions will be appreciated.

    The answer is yes... With certain caveats.

    That is their default libraries are hard coded to bypass the Serial object... I have a version of the library up at github...
    https://github.com/kurte/bioloidserial which is setup to handle on different Serial objects, like Serial1 on Arduino mega.

    You then need to wire it up to work half duplex... I have done this in the past connecting up the RX/TX pins of one of the Serial ports to each other and to the Data pin of an Bioloid connector and also needed to connect up a common ground...

    Note this does not provide the Arduino any protection from anything going wrong on the TTL data line. The AX12 manual shows their prefered hookup.... But I never had problems with hurting an Arduino...
