单片机编程，直流电机单极性双闭环PWM控制程序-microcontroller programming, Motor Unipolar double-loop PWM control procedures

MPC82G516单片机使用内部硬件PWM方式128细分、256细分方式驱动步进电机的程序，电路简单，成本极底，两路PWM就可以控制一只单极性的步进电机了。-MPC82G516 microcontroller using an internal hardware PWM mode 128 segments, 256 sub-way drive stepper motor program, the circuit is simple, cost very end, two PWM can cont

通过PIC16F73单极性做PWM控制作逆变器(By PIC16F73 unipolar, PWM control is used as inverter)
