STM32 ADC采集的三种方式

采样周期

单个采集模式

ADC_Settings:

程序使用

uint16_t ADC_Read(uint32_t Channel)
{
	ADC_ChannelConfTypeDef sConfig = {0};
	sConfig.Channel = Channel;                                         /* 通道 */
	sConfig.Rank = ADC_REGULAR_RANK_1;                              
	sConfig.SamplingTime = ADC_SAMPLETIME_55CYCLES_5;                  /* 采样时间 */
	if (HAL_ADC_ConfigChannel(&hadc1, &sConfig) != HAL_OK)             
	{
		Error_Handler();
	}
	HAL_ADC_Start(&hadc1);
	HAL_ADC_PollForConversion(&hadc1, HAL_MAX_DELAY);
	return (uint16_t)HAL_ADC_GetValue(&hadc1);
}

/*
	uint16_t ADC_Value[5];
	
	ADC_Value[0] = ADC_Read(ADC_CHANNEL_1);  // 采集并读取通道1
	ADC_Value[1] = ADC_Read(ADC_CHANNEL_4);
	ADC_Value[2] = ADC_Read(ADC_CHANNEL_5);
	ADC_Value[3] = ADC_Read(ADC_CHANNEL_6);
	ADC_Value[4] = ADC_Read(ADC_CHANNEL_7);
