写stm32的NTC103F3950的应用代码

以下是一个简单的基于STM32的NTC103F3950温度传感器应用代码：

#include "stm32f10x.h"

#define ADC1_DR_Address    ((uint32_t)0x4001244C)

ADC_InitTypeDef ADC_InitStructure;
GPIO_InitTypeDef GPIO_InitStructure;
DMA_InitTypeDef DMA_InitStructure;

volatile uint16_t ADC_ConvertedValue;

void RCC_Configuration(void);
void GPIO_Configuration(void);
void DMA_Configuration(void);
void ADC_Configuration(void);

int main(void)
{
    RCC_Configuration();
    GPIO_Configuration();
    DMA_Configuration();
    ADC_Configuration();
    while (1);
}

void RCC_Configuration(void)
{
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1 | RCC_APB2Periph_GPIOA | RCC_APB2Periph_DMA1, ENABLE);
}

void GPIO_Configuration(void)
{
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_1;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AIN;
    GPIO_Init(GPIOA, &GPIO_InitStructure);
}

void DMA_Configuration(void)
{
    DMA_DeInit(DMA1_Channel1);
    DMA_InitStructure.DMA_PeripheralBaseAddr = (uint32_t)ADC1_DR_Address;
    DMA_InitStructure.DMA_MemoryBaseAddr = (uint32_t)&ADC_ConvertedValue;
    DMA_InitStructure.DMA_DIR = DMA_DIR_PeripheralSRC;
    DMA_InitStructure.DMA_BufferSize = 1;
    DMA_InitStructure.DMA_PeripheralInc = DMA_PeripheralInc_Disable;
    DMA_InitStructure.DMA_MemoryInc = DMA_MemoryInc_Disable;
    DMA_InitStructure.DMA_PeripheralDataSize = DMA_PeripheralDataSize_HalfWord;
    DMA_InitStructure.DMA_MemoryDataSize = DMA_MemoryDataSize_HalfWord;
    DMA_InitStructure.DMA_Mode = DMA_Mode_Circular;
    DMA_InitStructure.DMA_Priority = DMA_Priority_High;
    DMA_InitStructure.DMA_M2M = DMA_M2M_Disable;
    DMA_Init(DMA1_Channel1, &DMA_InitStructure);
    DMA_Cmd(DMA1_Channel1, ENABLE);
}

void ADC_Configuration(void)
{
    ADC_DeInit(ADC1);
    ADC_InitStructure.ADC_Mode = ADC_Mode_Independent;
    ADC_InitStructure.ADC_ScanConvMode = DISABLE;
    ADC_InitStructure.ADC_ContinuousConvMode = ENABLE;
    ADC_InitStructure.ADC_ExternalTrigConv = ADC_ExternalTrigConv_None;
    ADC_InitStructure.ADC_DataAlign = ADC_DataAlign_Right;
    ADC_InitStructure.ADC_NbrOfChannel = 1;
    ADC_Init(ADC1, &ADC_InitStructure);
    ADC_RegularChannelConfig(ADC1, ADC_Channel_1, 1, ADC_SampleTime_239Cycles5);
    ADC_DMACmd(ADC1, ENABLE);
    ADC_Cmd(ADC1, ENABLE);
    ADC_ResetCalibration(ADC1);
    while (ADC_GetResetCalibrationStatus(ADC1));
    ADC_StartCalibration(ADC1);
    while (ADC_GetCalibrationStatus(ADC1));
    ADC_SoftwareStartConvCmd(ADC1, ENABLE);
}

在上面的代码中，我们首先进行了各种配置，然后通过DMA从ADC中读取转换值，并将其存储在变量ADC_ConvertedValue中。在主循环中，我们可以使用ADC_ConvertedValue来获取温度传感器NTC103F3950的实际温度。需要注意的是，由于NTC103F3950是一个负温度系数（NTC）热敏电阻，因此需要进行相应的计算来得到实际温度值。
