基于Verilog-HDL描述的多用途步进电机控制芯片的设计

A Solution of Stepper Motor Control Chip Based on VHDL

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 。

The paper introduced a solution of stepper motor control chip based on Verilog HDL . It could easily construct a control system of two phase bipolar or four phase unipolar stepper motor.The system can work just under the control signal of clock, direction and mode.The solution adopted several seperated modules.Such structure had perfect extendibility, and provided a practical way of low cost stepper motor control system.
