关于STM8S 的TIM1 PWM输出不了的问题

是否解决:

1、我参考了 STM8S_StdPeriph_Lib\Project\STM8S_StdPeriph_Examples\TIM1\TIM1_7PWM_Output的例程
2、照着库函数提供的去写，并没有PWM输出
3、我写的程序如下：

#include "stm8s.h"

void GPIO_Configuration(void)
{
  GPIO_DeInit(GPIOC);
  GPIO_Init(GPIOC, GPIO_PIN_6, GPIO_MODE_OUT_PP_LOW_SLOW);    //PC6低速推完输出低电平
  GPIO_Init(GPIOC, GPIO_PIN_7, GPIO_MODE_OUT_PP_LOW_SLOW);    //PC7低速推完输出低电平
  //GPIO_WriteHigh(GPIOC, GPIO_PIN_7);

}

//PC6 TIM1_CH1
//PC7 TIM_CH2
void TIM1_Configuraiton(void)
{
  TIM1_DeInit();
  TIM1_TimeBaseInit(1-1, TIM1_COUNTERMODE_UP, 8000-1, 0x00);    //  2kHz  (8000*1)/16000000
  TIM1_OC1Init(TIM1_OCMODE_PWM2, TIM1_OUTPUTSTATE_ENABLE, TIM1_OUTPUTNSTATE_DISABLE,
            2000, TIM1_OCPOLARITY_LOW, TIM1_OCNPOLARITY_HIGH, TIM1_OCIDLESTATE_SET,
            TIM1_OCNIDLESTATE_RESET);
  TIM1_OC2Init(TIM1_OCMODE_PWM2, TIM1_OUTPUTSTATE_ENABLE, TIM1_OUTPUTNSTATE_DISABLE, 2000,
            TIM1_OCPOLARITY_LOW, TIM1_OCNPOLARITY_HIGH, TIM1_OCIDLESTATE_SET,
            TIM1_OCNIDLESTATE_RESET);
  TIM1_Cmd(ENABLE);
  TIM1_CtrlPWMOutputs(ENABLE);
}

int main(void)
{
  CLK_HSIPrescalerConfig(CLK_PRESCALER_HSIDIV1);//内部时钟16M
  GPIO_Configuration();
  TIM1_Configuraiton();
  __enable_interrupt(); //打开中断
  while (1)
  {

  }
}

#ifdef USE_FULL_ASSERT

void assert_failed(u8* file, u32 line)
{

  while (1)
  {
  }
}
#endif
