It s typically applied in data acqu isition system. Step m otor ro tational speed contro l design based on STM 32 is introduced in this paper. Com- paring w ith tradit iona l sing lech ip, it hasm any advantages such as fast processing and perfect func ion. STM 32 m an ipulate step m oto r acco rd ing to senso r signa l and disp lay operating state. Th is article has g iven deta ils in hardw are design and softw are procedure, attach ing part o f exper mi ent descrip tion. Th is expermi ent system has proved to be stable and reliab le through practice, w hich is supposed to be great effect of expermi en t teaching.
