基于ARM9和QT的步进电机驱动控制系统设计与实现

摘要

This paper designs a S3C2440 microprocessor and the driving chip TA8435H control of the stepper motor drive system, and the Linux application Qt design and development of embedded control system and human-machine interface, through the touch screen to the stepper motor speed, direction, subdivision mode of control, the transfer process of QT applications is given, the transplantation process the cross compiler, the system interface is simple and intuitive, easy to operate, convenient.The motor control, so that it can be better applied to the field of industrial control.%本文设计了由S3C2440微处理器和驱动芯片TA8435H控制的步进电机驱动系统，并通过Linux 下应用Qt 设计开发嵌入式控制系统人机界面的方法，通过触摸屏对步进电机转速、方向、细分模式等进行控制，最后给出了QT应用程序的移植过程，移植过程采用交叉编译，系统界面直观简洁，易于操作，极大地方便了对电机的控制，使其更好地应用于工业控制领域。
