本文详细描述了如何在STM32F4微控制器中配置Timer13，包括时钟设置、GPIO功能配置、PWM通道初始化以及输出脉冲值和模式设置，以实现定时器的计数和PWM输出功能。

void timer13_config(void)
{
    timer_oc_parameter_struct timer_ocintpara;
    timer_parameter_struct timer_initpara；
    
    rcu_periph_clock_enable(RCU_TIMER13);
	rcu_periph_clock_enable(RCU_GPIOB);
	
    gpio_mode_set(GPIOB, GPIO_MODE_AF, GPIO_PUPD_NONE, GPIO_PIN_1);
    gpio_output_options_set(GPIOB, GPIO_OTYPE_PP, GPIO_OSPEED_MAX,GPIO_PIN_1);
    gpio_af_set(GPIOB, GPIO_AF_0, GPIO_PIN_1); 

    timer_deinit(TIMER13);

    /* TIMER1 configuration */

    timer_initpara.prescaler         = 9;

    timer_initpara.alignedmode       = TIMER_COUNTER_EDGE;
    timer_initpara.counterdirection  = TIMER_COUNTER_UP;
    timer_initpara.period            = 2700;
    timer_initpara.clockdivision     = TIMER_CKDIV_DIV1;
    timer_initpara.repetitioncounter = 0;
    timer_init(TIMER13,&timer_initpara);

    /* CH1,CH2 and CH3 configuration in PWM mode */
    timer_ocintpara.outputstate  = TIMER_CCX_ENABLE;
    timer_ocintpara.outputnstate = TIMER_CCXN_DISABLE;
    timer_ocintpara.ocpolarity   = TIMER_OC_POLARITY_HIGH;
    timer_ocintpara.ocnpolarity  = TIMER_OCN_POLARITY_HIGH;
    timer_ocintpara.ocidlestate  = TIMER_OC_IDLE_STATE_LOW;
    timer_ocintpara.ocnidlestate = TIMER_OCN_IDLE_STATE_LOW;

    timer_channel_output_config(TIMER13,TIMER_CH_0,&timer_ocintpara);

    timer_channel_output_pulse_value_config(TIMER13,TIMER_CH_0,1350);
    timer_channel_output_mode_config(TIMER13,TIMER_CH_0,TIMER_OC_MODE_PWM0);
    timer_channel_output_shadow_config(TIMER13,TIMER_CH_0,TIMER_OC_SHADOW_DISABLE);
	
	
    timer_primary_output_config(TIMER13, ENABLE);

    timer_enable(TIMER13);
    }
