首先要进行ADC校准以及要打开ADC通道。 代码如下(示例): /* USER CODE BEGIN 2 */ //校准ADC HAL_ADCEx_Calibration_Start(&hadc3,ADC_CALIB_OFFSET,ADC_SINGLE_ENDED); //打开ADC3 HAL_ADC_Start(&hadc3); /* USER CODE END 2 */ } 1. 2. 3. 4. 5. 6. 7. 8. 其次进行AD采集以及开始运用...

首先使用的时候要校准一下ADC,然后开启一次DMA转换即可因为开启了ADC连续模式并且开启了DMA, 校准ADC的API: HAL_ADCEx_Calibration_Start(&hadc1,ADC_SINGLE_ENDED); 开启ADC DMA传输的API: if ( HAL_ADC_Start_DMA(&hadc1,(uint32_t *)&ADC_Value,1) != HAL_OK) { Error_Handler(); } 最后我们使...
