STM8S003F3 PWM的使用

这里我使用timer1，gpio PC3来举例：

GPIO_Init(GPIOC, GPIO_PIN_3, GPIO_MODE_OUT_PP_LOW_FAST);   

TIM1_DeInit(); 

TIM1_TimeBaseInit(0x01, TIM1_COUNTERMODE_UP, 10000, 0x00); 

TIM1_OC3Init(TIM1_OCMODE_PWM1, TIM1_OUTPUTSTATE_ENABLE,TIM1_OUTPUTNSTATE_DISABLE, 5000, TIM1_OCPOLARITY_LOW,TIM1_OCNPOLARITY_LOW, TIM1_OCIDLESTATE_RESET,TIM1_OCNIDLESTATE_RESET);//50%占空比 

TIM1_CCxCmd(TIM1_CHANNEL_3, ENABLE); 

TIM1_OC3PreloadConfig(ENABLE); 

TIM1_CtrlPWMOutputs(ENABLE); 

TIM1_Cmd(ENABLE);
