Referring to the topic above, I failed to drive my stepper motor with the driver. If I don't use UART, by sending pulse of 1000 ms into the pulse port, nothing happen? On and Off continuosly, what should i send in to control the rotation of stepper motor?? If I want to use arduino digital port like port 13 to send in the pulse, what kind of pulse or program should i use? Need help in urgent, Thanks.
