problems with stepper and DC motors

Posted by Grottini Communication at September 04. 2008

Hi,
I've just bought my first KIT and I'm testing all sensor and motors. Everything working well, but problems with two motors.

DC motor:
I followed what explained in this page: http://www.makingthings.com/documentation/how-to/connect-a-dc-motor
1) connected the motor as in figure, and then give these command from MCH:

/digitalout/1/value 1
/motor/0/active 1

and then trying to set the speed, but asking for /motor/0/active the value remains always at 0.

The same with the stepper motor: after finded the couple of wires, connected a couple to Out0 and Out1 and the other to Out2 and Out3, give the commands explained here but nothing moves.

What's wrong? The board is powered from an external AC adapter.

Another question: what is the aim of digitalout.fla? Getting able single output or what?

Really sorry for my bad english, regards.

Andrea

If you set the digitalout to active, then the motor won't be able to work. This is because they share the same output line, which only one can use at a time. Don't send any digitalout messages and the motor system should be able to work as expected.
