我找到的一篇51控制步进电机的工程有简单的源代码，可以给那些想设计步进电机驱动的人一些帮助。-I found a 51 stepper motor control project has a simple source code, can give those who want to design stepper motor-driven to help people.

采用正弦/ 余弦细分方案,通过嵌入cos/ sin 表格于FPGA 中,合理控制步进电机两相绕组的电流,实现斩波恒流均匀细分驱动,减小了步距角、提高了步进分辨率,最高细分达到256 。-Using sine/cosine segment program, by embedding cos/sin table in the FPGA, the reasonable control of two-phase stepper motor winding current to achieve const
