1  Development / Other Hardware Development / 2MOTOR-4NANO Gravitech Problem on: November 09, 2012, 03:59:03 pm
Does anyone know how to program this shield so that it controls a stepper motor in a 3 state system?

There is little support documentation for this shield and the nano. The examples are not working and I dont know what to try.

Hello All,

I cannot seem to get my Matlab software to control my hardware:

http://www.gravitech.us/2mwfecoadfor.html
http://www.arduino.cc/en/Main/ArduinoBoardNano

1. If I get a solid connection after loading a .pde file and installing a the Afmotor library on the nano and all I get is a large printout saying that the Arduino was successfully connected to MATLAB, but the pins are unassigned, how do I assign those darn pins?

int motorpin1(6) or something? and if so wont I delete the whole motorsrv.pde file form the board that made a connection to mat-lab even possible?

2. Do I need to alter the motorsrv.pde file that I found on the MATLAB support I/O pack in order to suit the Nano or are they fine for all boards, driveshield and steppers?

PLease EMail me or respond to this !

1. Can the Nano operate a stepper motor using this Gravitech drive shield? The support man at robotshop.com says it has never been done before is this true?

2. Does it matter which way I screw the 4-wires form the bipolar stepper into the green terminals as long as I have found the ones that are paired using a multi meter. So that I screwed the paired leads into either the (A1 & A2) or the (B1 & B2) terminals.
