arr重装载周期，psc预分频值，频率=72000000（如果没有特意改变主频）/（arr*psc）。也就是说，这个程序里预分频值psc=0，也就是1分频，再用72000000除以arr为900就是PWM频率了

舵机的控制时,PWM周期的初始化函数是TIM3_PWM_Init(200,7200);那么让通道二的PWM的高电平的宽度是2ms,那么占空比设置函数应该是哪个A.TIM_SetCompare1(TIM3,10);B.TIM_SetCompare1(TIM3,20);C.TIM_SetCompare2(TIM3,10);D.TIM_SetCompare2(TIM3,20);的答案是什么.用刷刷题
