stm32adc温度采集 hal库

以下是使用HAL库在STM32上进行温度采集的示例代码：

首先，需要启用ADC和温度传感器的时钟：

__HAL_RCC_ADC1_CLK_ENABLE();
__HAL_RCC_GPIOA_CLK_ENABLE();
ADC_HandleTypeDef hadc;
GPIO_InitTypeDef GPIO_InitStruct;
GPIO_InitStruct.Pin = GPIO_PIN_1;
GPIO_InitStruct.Mode = GPIO_MODE_ANALOG;
GPIO_InitStruct.Pull = GPIO_NOPULL;
HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);

接下来，需要配置ADC：

hadc.Instance = ADC1;
hadc.Init.ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV2;
hadc.Init.Resolution = ADC_RESOLUTION_12B;
hadc.Init.ScanConvMode = DISABLE;
hadc.Init.ContinuousConvMode = DISABLE;
hadc.Init.DiscontinuousConvMode = DISABLE;
hadc.Init.NbrOfDiscConversion = 0;
hadc.Init.ExternalTrigConvEdge = ADC_EXTERNALTRIGCONVEDGE_NONE;
hadc.Init.ExternalTrigConv = ADC_SOFTWARE_START;
hadc.Init.DataAlign = ADC_DATAALIGN_RIGHT;
hadc.Init.DMAContinuousRequests = DISABLE;
hadc.Init.EOCSelection = ADC_EOC_SINGLE_CONV;
hadc.Init.LowPowerAutoWait = DISABLE;
hadc.Init.Overrun = ADC_OVR_DATA_OVERWRITTEN;
HAL_ADC_Init(&hadc);

然后，需要启用ADC温度传感器：

ADC_ChannelConfTypeDef sConfig;
sConfig.Channel = ADC_CHANNEL_TEMPSENSOR;
sConfig.Rank = ADC_REGULAR_RANK_1;
sConfig.SamplingTime = ADC_SAMPLETIME_480CYCLES;
sConfig.SingleDiff = ADC_SINGLE_ENDED;
sConfig.OffsetNumber = ADC_OFFSET_NONE;
sConfig.Offset = 0;
HAL_ADC_ConfigChannel(&hadc, &sConfig);

最后，可以使用以下代码读取温度值：

HAL_ADC_Start(&hadc);
if (HAL_ADC_PollForConversion(&hadc, 1000) == HAL_OK)
{
    uint16_t adc_value = HAL_ADC_GetValue(&hadc);
    float temperature = (1.43 - ((float)adc_value * 3.3 / 4096)) / 0.0043 + 25;
}

以上就是使用HAL库在STM32上进行温度采集的示例代码。
