基于可编程逻辑阵列的SMT检测步进电机脉冲分配器的设计与实现

Design and realization of stepping motor pulse distributor that applied to SMT detection based on generic array logic

针对SMT检测定位高精度的要求,提出了步进电机运动控制方案,以AT89C55单片机为控制核心,利用可编程逻辑阵列器件GAL16V8作为环形脉冲分配器,实现步进电机的控制。给出了软硬件设计方法。

This paper puts forward the controlling scheme of stepping motor by the demand for high precision of SMT detecting orientation,which make use of generic array logic GAL16V8 as cycle pulse distributor to control stepping motor with micro control unit AT89C55 as control core.It also gives its design procedures of hardware and software.
