介绍了一种基于 Verilog- HDL描述的多功能步进电机控制芯片的可综合方案 ,该方案可方便地构成两相双极或四相单极步进电机的控制系统。外接元件极少 ,只需给定时钟、转向以及工作模式信号 ,就可使系统工作。该方案采用模块化设计 ,可扩展性好 ,为步进电机的低成本控制提供了一种新的思路和实现方法 A synthesizable solution of multi-function stepping motor control chip based on Verilog HDL is introduced, which can easily form the control system of two-phase bipolar or four-phase unipolar stepping motor. Very few external components, just given the clock, steering and operating mode signal, you can make the system work. The program uses a modular design, scalability is good for the low cost of stepper motor control provides a new way of thinking and implementation
