【iCore4 双核心板_ARM】例程三十六：DAC实验——输出直流电压

实验现象：

用电压表测量PA4引脚有2.0V直流电压输出。

核心代码：

int main(void)
{

  /* USER CODE BEGIN 1 */

  /* USER CODE END 1 */

  /* MCU Configuration----------------------------------------------------------*/

  /* Reset of all peripherals, Initializes the Flash interface and the Systick. */
  HAL_Init();

  /* USER CODE BEGIN Init */

  /* USER CODE END Init */

  /* Configure the system clock */
  SystemClock_Config();

  /* USER CODE BEGIN SysInit */

  /* USER CODE END SysInit */

  /* Initialize all configured peripherals */
  MX_GPIO_Init();
  MX_DAC_Init();

  /* USER CODE BEGIN 2 */
    LED_GREEN_ON;
    HAL_DAC_Start(&hdac, DAC_CHANNEL_1); //¿ªÆôDACͨµÀ1
    dac1.set_voltage(2.0);
  /* USER CODE END 2 */

  /* Infinite loop */
  /* USER CODE BEGIN WHILE */
  while (1)
  {
  /* USER CODE END WHILE */

  /* USER CODE BEGIN 3 */

  }
  /* USER CODE END 3 */

}
