FPGA 帧同步源代码 调试无错误 ALTERA 平台(Frame synchronization FPGA)

本程序设计一个基于FPGA的4相步进电机定位控制系统。由步进电机方向设定电路模块、步进电机步进移动与定位控制模块和编码输出模块构成。前两个模块完成电机旋转方向设定，激磁方式设定和定位角度的换算等工作，后一个模块用于对换算后的角度量编码输出。-This procedure to design an FPGA-based 4-phase stepper motor positioning control system. Direction set by the stepper motor circuit module, stepper motor stepper movement and positioning control module and the code output modules. The first two modules complete the motor rotation direction setting, exciting way of setting the angle and positioning of the conversion work, after a module for the point of view of the volume of converted output encoding.
