DAC_Init(DAC_Channel_1 , &DAC_InitStructure); 这个初始化函数的第一个参数你们是怎么找到的？

  /* Check the DAC parameters */
  assert_param(IS_DAC_TRIGGER(DAC_InitStruct->DAC_Trigger));
  assert_param(IS_DAC_GENERATE_WAVE(DAC_InitStruct->DAC_WaveGeneration));
  assert_param(IS_DAC_LFSR_UNMASK_TRIANGLE_AMPLITUDE(DAC_InitStruct->DAC_LFSRUnmask_TriangleAmplitude));
  assert_param(IS_DAC_OUTPUT_BUFFER_STATE(DAC_InitStruct->DAC_OutputBuffer));
/*---------------------------- DAC CR Configuration --------------------------*/


我看库函数里只有这个四个参数的有效性检查
