在同步控制上，应用了“优先与抢占”的方式产生同步信号，纯硬件实现，简单可靠；使用了成熟的数字锁相环来跟踪同步信号。-A strategy of synchronization control, which combines competition coequality and priority, is mentioned in the paper and uses digital phase-lock loop to track synchronization signal

本源码是基于FPGA来控制步进电机运行上位机发出的精确步数，并能够实时跟踪步进电机行进的位置，通过UART接口与上位机进行串口通信。-The source code is based on FPGA to control the stepper motor running the host computer to send the exact number of steps, and can track the location of the stepper motor in real time
