STM8S003定时器2产生PWM

可对初学者有一定借鉴作用

//开时钟

CLK_PeripheralClockConfig(CLK_PERIPHERAL_TIMER2, ENABLE);

//赋值前先关

TIM2_DeInit();

TIM2_Cmd(DISABLE);

TIM2_TimeBaseInit(TIM2_PRESCALER_2, 1427);//1427*1us=700HZ

//PWM1 Mode configuration: Channel3,50%

TIM2_OC3Init(TIM2_OCMODE_PWM1, TIM2_OUTPUTSTATE_ENABLE,713, TIM2_OCPOLARITY_HIGH);

//捕获比较寄存器CCR1

TIM2_OC3PreloadConfig(ENABLE);

//自动装载寄存器ARR

TIM2_ARRPreloadConfig(ENABLE);

TIM2_Cmd(ENABLE);
