由DSP输出脉冲对步进电机进行启动、制动、相位、方向、速度、位置等控制。例如：设计程序，使步进电动机实现间断性步进（30步，间隔0.5秒）→连续正转（60步，间隔0.1秒）→停顿（2秒）→反向间断性步进（30步，间隔0.5秒）→连续反转（60步，间隔0.1秒）。-By DSP for step motor output pulse to start, brake, phase, direction, speed, position control. For example: design program, make stepping motor realize intermittent step (30 step, interval 0.5 seconds) and continuous are turning (60 step, interval 0.1 seconds)-pause (2 seconds) and step into reverse intermittent (30 step, interval 0.5 seconds) and continuous reversed (60 step, interval 0.1 seconds).
