I,m using a stepper motor of 400 steps per revolutiuon 0.9º step. It is the 0.9 version of this http://catalog.orientalmotor.com/item/stepping-motors/pk-series-stepping-motors/pk266-e2-0b?jumpMenu=%23
and an external driver DS1044 to control it ,which if receives a 5v On Off will make a motor Step.
So by switching on and off a pin it will move this works well so far.
what i would like is to be able to set an apropiate pwm , by using normal Analogwrite the motor moves at its maximum speed and changing from 1-254 will not produce any difference in speed, so i presume it is because the range it is already at its maximum and that it is why it does not change .
searching around i tried a few things like this :
using it and setPwmFrequency(6, x); changing to all options did not produce any change either so i still presume even slower frequency is still too fast.
any ideas or things i could try to achive a moderable pwm pulse to change speed of the motor , btw i.m using an arduino mega 2560 and if posible i,d like to use pin 8 for that.
In the past i used some stepper motors with the stepper shields , will the motors libraries be able to output that pulse ? as i remember they will affecting the motor directly using 4 output pins.
