仅仅使用L298驱动芯片，主控为51单片机，在keil中调试测过，专门驱动步进电机的！不是直流电机。-Just use the L298 driver chip, the master microcontroller 51, in keil debugging measured before, specifically to drive stepper motor! Not a DC motor.

一个简单的步进电机测试程序，用L297,和L298芯片带动步进电机-A simple stepper motor test program, with the L297, and L298-chip stepper motor drive

运用L298驱动直流电机，代码中包含有正转、反转、停止等程序。-DC motor driver using L298, the code contains a forward, reverse, stop and other procedures.
