I'm new here and got a problem: My stepper motor wont work with the Romeo controller (the Romeo has an L298P controller included). When I start the sample script 'stepper_oneRevolution', the motor does turn clock- and counterclockwise, but with many interrupts and stops, it moves just not steady.
So after some experiments, i figured out, that the pins 4 and 7 doenst seem to work at all:
This would be how i expected it to work fine:
Stepper myStepper(stepsPerRevolution, 4,5,6,7);
And when i change pins 4 and 7 to some other numbers:
Stepper myStepper(stepsPerRevolution, 1,5,6,2);
it makes no difference, the motor works, but not steady.
So anybody some ideas or experience with the Romeo and stepper motors ?
