SoftwareSerial resets arduino pro mini

[Blue_Eyes]

You are overwriting the array here:

    byte inc[7];
    bool xmp = false;
    for(int i=0;i<=7;i++)
    {
      inc[i] = zb.read();
    }

I think you want:

    byte inc[7];
    bool xmp = false;
    for(int i=0;i<7;i++)
    {
      inc[i] = zb.read();
    }
