摘要
方案基于51单片机,通过驱动芯片ULN2003A,以软件模拟PWM的方法实现对步进电机式汽车仪表机芯的细分驱动,从而使步进电机式汽车仪表机芯的细分能在常见的51单片机上得以实现.方案详细介绍了电路的组成、工作原理及编程思想.
The project based on 51 MCU applied ULN2003A to subdivision drive dashboard stepping mo- tor,employing software simulation of PWM. The subdivision driver of dashboard stepping motor can be accomplished on the common 51 MCU. The project introduces in detail the frame work of circuits,work- ing principle and its programming.
