PWM控制电机,编辑控制方式。在这个DEMO里建了一个函数F_Pwm(int a,int b) 用于PWM设置，传入两个参数第一个用于频率设置，第二个用于占空比设置。另外还开了外部中断可进行频率和占空比的步进，从而达到调整速度的目的-PWM motor control, edit control mode. In this DEMO was built inside a function F_Pwm (int a, int b) for the PWM settings, with two arguments the first one for the frequency setting, the second set for the duty cycle. It also opened the external interrupt can be the stepping frequency and duty cycle to achieve the purpose of adjusting the speed of
