定时器频率和PWM原理见PID详解3(摄像头循迹分析)_遗忘是原罪的博客-CSDN博客_摄像头寻迹

APB2设置为72M，72M/(72*1000) = 72 * 1000000/72000 = 1000HZ = 1KHZ

  HAL_TIM_PWM_Start(&htim1,TIM_CHANNEL_1);
  HAL_TIMEx_PWMN_Start(&htim1,TIM_CHANNEL_1);
  HAL_TIM_PWM_Start(&htim1,TIM_CHANNEL_2);
  HAL_TIMEx_PWMN_Start(&htim1,TIM_CHANNEL_2);
  HAL_TIM_PWM_Start(&htim1,TIM_CHANNEL_3);
  HAL_TIMEx_PWMN_Start(&htim1,TIM_CHANNEL_3);

__HAL_TIM_SET_COMPARE(&htim1,TIM_CHANNEL_1,CCR);

试验验证，可输出波形

示波器看死区成功
