摘　　要：主要介绍了由AVR单片机为核心的四相八拍步进电机的驱动设计，并用电路图、数据表格和子程序的方式说明了四相八拍步进电机的硬件驱动原理和驱动软件的设计实现。采用了35BYJ46型四相八拍步电动机，通过对AVR单片机Atmega8的I／O口编程实现对步进电机的环形分配器驱动编码，采用了达林顿管电路ULN2003驱动设计，通过程序改变步进电机的方向和速度，实现了对步进电机的稳定、可靠控制。A method based on AVR microcontroUer, drivering the four phase4eight clap stepping motor was introduced. Through the form of circuit diagram, data table and subroutine, the working principle and software design ideas were described. The four step motor in eight clap of 35BYJ46 type was used to achieve the driver design through AVR microcontroller Atmega8 I/O port for the programming of stepping motor driver code, and the annular allocator driving circuit was achieved by da linton tube circuit ULN2003. The stable and reliable control of the stepping motor was realized through programming the stepper motor directional control and speed regulation.
