STM32F103, DAC, IO, pi, ni

以下是我的代码，求大神们帮忙看看哪里有错！谢了！
//主函数
int main(void)
{
      DAC_Configuration();
      while(1)
      {

      }
}
//DAC配置函数

void DAC_Configuration(void)
{
      DAC_InitTypeDef DAC_InitStruct;
      GPIO_InitTypeDef GPIO_InitStruct;

      RCC_APB2PeriphClockCmd( RCC_APB2Periph_GPIOA, ENABLE );
      RCC_APB1PeriphClockCmd( RCC_APB1Periph_DAC, ENABLE );

      GPIO_InitStruct.GPIO_Pin = GPIO_Pin_4;
      GPIO_InitStruct.GPIO_Mode = GPIO_Mode_Out_PP;
      GPIO_InitStruct.GPIO_Speed = GPIO_Speed_50MHz;
      GPIO_Init( GPIOA, &GPIO_InitStruct );

      DAC_InitStruct.DAC_Trigger = DAC_Trigger_Software;
      DAC_InitStruct.DAC_WaveGeneration = DAC_WaveGeneration_None;
      DAC_InitStruct.DAC_LFSRUnmask_TriangleAmplitude = DAC_LFSRUnmask_Bit0;
      DAC_InitStruct.DAC_OutputBuffer = DAC_OutputBuffer_Disable;

      DAC_Init( DAC_Channel_1, &DAC_InitStruct );
      DAC_Cmd( DAC_Channel_1, ENABLE );
      DAC_SetChannel1Data( DAC_Align_12b_R, 0X0FFF );
      DAC_SoftwareTriggerCmd( DAC_Channel_1, ENABLE );
}
