stm8s003 tim1 pwm输出求助

问答
是否解决:

各个大哥好，stm8s003的tim1一直发不了脉冲，程序如下：
void TIM1_init(void)
{
  TIM1_DeInit();
  TIM1_TimeBaseInit(0,TIM1_COUNTERMODE_UP,200,0);
// TIM1_CCxCmd(TIM1_CHANNEL_1, ENABLE);

  TIM1_OC1Init(TIM1_OCMODE_PWM2, TIM1_OUTPUTSTATE_DISABLE, TIM1_OUTPUTNSTATE_DISABLE, 100, TIM1_OCPOLARITY_HIGH, TIM1_OCNPOLARITY_HIGH, TIM1_OCIDLESTATE_RESET, TIM1_OCNIDLESTATE_SET);

  TIM1_ARRPreloadConfig(ENABLE);
  TIM1_OC1PreloadConfig(ENABLE);

  TIM1_CtrlPWMOutputs(ENABLE);
  TIM1_Cmd(ENABLE);
}

请问有哪里需要改动的，另外，直接写寄存器的也不行
void TIM1_init(void)
{
TIM1->PSCRH=0;//分频系数为0，定时器时钟为8M/(1+0)=8M
TIM1->PSCRL=0;

  TIM1->ARRH=0x00;
  TIM1->ARRL=0xC8;//频率调为40k

  TIM1->CCMR1 =0x78;//通道1配置成比较输出模式,PWM2模式
//  TIM1->CCER1 |=0x03;//开启通道1引脚，低电平有效
  TIM1->CCER1=0x03;
//初始化CCR1，占空比为50%；
  TIM1->CCR1H=0x00;
  TIM1->CCR1L=0x64;
  TIM1->RCR|=0x01;
  TIM1->EGR=0x01;

//  TIM1->CNTRH=0;
//  TIM1->CNTRL=0;
  TIM1->BKR =0x80;
  TIM1->CR1 =0x01;//启动定时器1
}

谢谢！
