FPGA实现步进电机控制源代码。通过脉冲信号控制，产生一定频率脉冲的信号（脉冲频率用来控制速度），经过信号隔离放大（达到驱动电机的电压）来驱动控制步进电机-FPGA Implementation of stepper motor control source code. Controlled by the pulse signal, generating a frequency pulse signal (pulse frequency is used to control speed), via a signal isolation amplifier (up to the voltage of the drive motor) to drive the stepper motor
