stm32 pwm控制舵机转动

使用pwm驱动舵机转动至不同角度 main.c： #include "sys.h" #include "delay.h" #include "usart.h" #include "led.h" #include "pwm.h" int main(void) { u16 out_led0pwmval=1950; //u8 dir=1; u16 led0pwmval=1850; NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2); delay_init(168); //³õʼ»¯ÑÓʱº¯Êý uart_init(115200);//³õʼ»¯´®¿Ú²¨ÌØÂÊΪ115200 TIM14_PWM_Init(2000-1,840-1); //84M/84=1MhzµÄ¼ÆÊýƵÂÊ,ÖØ×°ÔØÖµ500£¬ËùÒÔPWMƵÂÊΪ 1M/500=2Khz. --90-90-=0=-0900-0== while(1) { delay_ms(10); if(led0pwmval<1900){led0pwmval++;TIM_SetCompare1(TIM14,out_led0pwmval);} else { if(led0pwmval>1900){out_led0pwmval--;TIM_SetCompare1(TIM14,out_led0pwmval);} if(1900>led0pwmval >0){out_led0pwmval--;TIM_SetCompare1(TIM14,out_led0pwmval);} if(out_led0pwmval==0){led0pwmval=1900;out_led0pwmval=1950;} //Ð޸ıȽÏÖµ£¬ÐÞ¸ÄÕ¼¿Õ±È } } } 转动角度可自行设置，知道原理便可举一反三！加油！
