我照着库里给的历程把timer1-ch0改成timer2-ch3就可以，但是改成timer0-ch0就不行了，高级定时器配置有什么不一样吗
原带的配置：
void timer_config(void)
{
timer_oc_parameter_struct timer_ocintpara;
timer_parameter_struct timer_initpara;
/* TIMER1 configuration */
timer_initpara.prescaler = 8399;
timer_initpara.alignedmode = TIMER_COUNTER_EDGE;
timer_initpara.counterdirection = TIMER_COUNTER_UP;
timer_initpara.period = 9999;
timer_initpara.clockdivision = TIMER_CKDIV_DIV1;
timer_initpara.repetitioncounter = 0;
timer_init(TIMER1,&timer_initpara);
/* CH0 configuration in PWM mode1 */
timer_ocintpara.ocpolarity = TIMER_OC_POLARITY_HIGH;
timer_ocintpara.outputstate = TIMER_CCX_ENABLE;
timer_channel_output_config(TIMER1, TIMER_CH_0, &timer_ocintpara);
timer_channel_output_pulse_value_config(TIMER1, TIMER_CH_0, 3999);
timer_channel_output_mode_config(TIMER1, TIMER_CH_0, TIMER_OC_MODE_PWM1);
timer_channel_output_shadow_config(TIMER1, TIMER_CH_0, TIMER_OC_SHADOW_DISABLE);
}
改后的配置：
void timer_config(void)
{
timer_oc_parameter_struct timer_ocintpara;
timer_parameter_struct timer_initpara;
timer_deinit(TIMER0);
/* TIMER1 configuration */
timer_initpara.prescaler = 8399;
timer_initpara.alignedmode = TIMER_COUNTER_EDGE;
timer_initpara.counterdirection = TIMER_COUNTER_UP;
timer_initpara.period = 9999;
timer_initpara.clockdivision = TIMER_CKDIV_DIV1;
timer_initpara.repetitioncounter = 0;
timer_init(TIMER0,&timer_initpara);
/* CH0 configuration in PWM mode1 */
timer_ocintpara.ocpolarity = TIMER_OC_POLARITY_HIGH;
timer_ocintpara.outputstate = TIMER_CCX_ENABLE;
timer_channel_output_config(TIMER0, TIMER_CH_3, &timer_ocintpara);
timer_channel_output_pulse_value_config(TIMER0, TIMER_CH_3, 3999);
timer_channel_output_mode_config(TIMER0, TIMER_CH_3, TIMER_OC_MODE_TIMING);
timer_channel_output_shadow_config(TIMER0, TIMER_CH_3, TIMER_OC_SHADOW_ENABLE);
