本人使用STM32L431RCT6单片机和STM32CUBEMX配置ADC进行内部温度采集，程序如下：

/ ADC1 init function / void MX_ADC1_Init(void) {

/ USER CODE BEGIN ADC1_Init 0 /

/ USER CODE END ADC1_Init 0 /

ADC_ChannelConfTypeDef sConfig = {0};

/ USER CODE BEGIN ADC1_Init 1 /

/ USER CODE END ADC1_Init 1 /

/* Common config / hadc1.Instance = ADC1; hadc1.Init.ClockPrescaler = ADC_CLOCK_ASYNC_DIV16; hadc1.Init.Resolution = ADC_RESOLUTION_12B; hadc1.Init.DataAlign = ADC_DATAALIGN_RIGHT; hadc1.Init.ScanConvMode = ADC_SCAN_DISABLE; hadc1.Init.EOCSelection = ADC_EOC_SINGLE_CONV; hadc1.Init.LowPowerAutoWait = DISABLE; hadc1.Init.ContinuousConvMode = DISABLE; hadc1.Init.NbrOfConversion = 1; hadc1.Init.DiscontinuousConvMode = DISABLE; hadc1.Init.ExternalTrigConv = ADC_SOFTWARE_START; hadc1.Init.ExternalTrigConvEdge = ADC_EXTERNALTRIGCONVEDGE_NONE; hadc1.Init.DMAContinuousRequests = DISABLE; hadc1.Init.Overrun = ADC_OVR_DATA_PRESERVED; hadc1.Init.OversamplingMode = DISABLE; if (HAL_ADC_Init(&hadc1) != HAL_OK) { Error_Handler(); }

/* Configure Regular Channel / sConfig.Channel = ADC_CHANNEL_TEMPSENSOR; sConfig.Rank = ADC_REGULAR_RANK_1; sConfig.SamplingTime = ADC_SAMPLETIME_2CYCLES_5; sConfig.SingleDiff = ADC_SINGLE_ENDED; sConfig.OffsetNumber = ADC_OFFSET_NONE; sConfig.Offset = 0; if (HAL_ADC_ConfigChannel(&hadc1, &sConfig) != HAL_OK) { Error_Handler(); } / USER CODE BEGIN ADC1_Init 2 /

/ USER CODE END ADC1_Init 2 /

}

采集AD程序如下：

void GetInternalTemp(void) { HAL_ADC_Start(&hadc1); HAL_ADC_PollForConversion(&hadc1, 0xff); if(HAL_IS_BIT_SET(HAL_ADC_GetState(&hadc1), HAL_ADC_STATE_REG_EOC)) { ADC_Value = (float)HAL_ADC_GetValue(&hadc1);

ADC_Value = ADC_Value*3.0/2.5;
measure.temperture_internal = (float)((ADC_Value-*TEMP30_CAL_ADDR)*1.0/(int16_t)(*TEMP130_CAL_ADDR-*TEMP30_CAL_ADDR))+30;

} }

可以获取AD值，但是AD值随温度不变化，求助这是什么原因导致的
