将 DAC_InitStructure.DAC_Trigger = DAC_Trigger_T2_TRGO; DAC_InitStructure.DAC_WaveGeneration = DAC_WaveGeneration_None; DAC_InitStructure.DAC_OutputBuffer = DAC_OutputBuffer_Disable; DAC_Init(DAC_Channel_1, &DAC_InitStructure); 改写为hal库环境

在HAL库环境下，将上述代码改写为下面的方式：

DAC_HandleTypeDef hdac;

hdac.Instance = DAC;
if (HAL_DAC_Init(&hdac) != HAL_OK)
{
  /* 初始化失败 */
  Error_Handler();
}

DAC_ChannelConfTypeDef sConfig;
sConfig.DAC_Trigger = DAC_TRIGGER_T2_TRGO;
sConfig.DAC_OutputBuffer = DAC_OUTPUTBUFFER_DISABLE;
if (HAL_DAC_ConfigChannel(&hdac, &sConfig, DAC_CHANNEL_1) != HAL_OK)
{
  /* 配置通道失败 */
  Error_Handler();
}

以上代码假设您已经正确初始化了DAC外设，并将其命名为"hdac"。如果没有初始化DAC外设，请先进行初始化操作。
