摘要
介绍具有ARM7TDMI内核的微控制器ST30F772A,分析步进电机的工作原理,并提出一种有效的驱动方法。结果显示,步进电机运行效果理想。同时,该方法具有极低的运算量,非常适合运算能力相对较弱的嵌入式应用。
The authors introduce the micro-controller_ST30F772A with ARM7 TDMI core,analyze the functioning principles of stepper motor and suggest an effective method for its driving.The result reveals that the stepper motor produces the expected effects.Furthermore,this method only requires a small number of calculations,which is quite suitable for the embedded application with a relatively low calculating power.
