hello sich , ya , i am talking about the PR7, code . thank you for ur explanation .
hmm , now i will like to share with you guys another difficulty i am facing now
for testing , i have connect my driver as follows :
the direction and enable pins all go to 5 v and for the pulse , i use the ccp1l , that is the one one use for pwm for dc motor . that is , i am feeding the stepper motor driver with the pulse generated through pwm .
but as i am oding that
the stepper, is not actually rotating
when i touch the motor shaft, it is just as if it want to turn but , the there is not enough power , i recharge my 12v battery and retry and the same thing
instead of the rotation , i am getting a sort of periodical inner vibrations .
plss help
