Im facing some issues to figure out sequence of my bipolar(specifically) and unipolar stepper motor. However , I've managed to get Dual H Bridge but couldn't find out the example/documentation for the one i got.
I want to drive my bipolar stepper motor via dual h bridge using parallel port and unipolar via IC UN2003.
You're expert guidennce for pulse sequence and wiring identification will be truly appriciable. Thanks!!
