以下是基于Keil MDK开发环境的温感连接代码示例:
```c
#include "stm32f10x.h"
#include "stdio.h"
#define ADC1_DR_Address ((uint32_t)0x4001244C)
__IO uint16_t ADCConvertedValue;
void ADC1_Configuration(void);
void USART1_Configuration(void);
int main(void)
{
char str[50];
float temperature;
ADC1_Configuration();
USART1_Configuration();
while (1)
{
ADC_SoftwareStartConvCmd(ADC1, ENABLE);
while(ADC_GetFlagStatus(ADC1, ADC_FLAG_EOC) == RESET);
ADCConvertedValue = ADC_GetConversionValue(ADC1);
temperature = (float)ADCConvertedValue/4096*3.3/0.005;
sprintf(str, "Temperature: %.1f C\r\n", temperature);
USART_SendString(USART1, str);
Delay(1000);
}
}
void ADC1_Configuration(void)
{
GPIO_InitTypeDef GPIO_InitStructure;
ADC_InitTypeDef ADC_InitStructure;
RCC_ADCCLKConfig(RCC_PCLK2_Div8);
RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1 | RCC_APB2Periph_GPIOA, ENABLE);
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AIN;
GPIO_Init(GPIOA, &GPIO_InitStructure);
ADC_InitStructure.ADC_Mode = ADC_Mode_Independent;
ADC_InitStructure.ADC_ScanConvMode = DISABLE;
ADC_InitStructure.ADC_ContinuousConvMode = DISABLE;
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_0, 1, ADC_SampleTime_55Cycles5);
ADC_Cmd(ADC1, ENABLE);
ADC_ResetCalibration(ADC1);
while(ADC_GetResetCalibrationStatus(ADC1));
ADC_StartCalibration(ADC1);
while(ADC_GetCalibrationStatus(ADC1));
}
void USART1_Configuration(void)
{
GPIO_InitTypeDef GPIO_InitStructure;
USART_InitTypeDef USART_InitStructure;
RCC_APB2PeriphClockCmd(RCC_APB2Periph_USART1 | RCC_APB2Periph_GPIOA, ENABLE);
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_Init(GPIOA, &GPIO_InitStructure);
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_10;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
GPIO_Init(GPIOA, &GPIO_InitStructure);
USART_InitStructure.USART_BaudRate = 115200;
USART_InitStructure.USART_WordLength = USART_WordLength_8b;
USART_InitStructure.USART_StopBits = USART_StopBits_1;
USART_InitStructure.USART_Parity = USART_Parity_No;
USART_InitStructure.USART_HardwareFlowControl = USART_HardwareFlowControl_None;
USART_InitStructure.USART_Mode = USART_Mode_Rx | USART_Mode_Tx;
USART_Init(USART1, &USART_InitStructure);
USART_Cmd(USART1, ENABLE);
}
void USART_SendString(USART_TypeDef* USARTx, char* string)
{
while(*string)
{
while(USART_GetFlagStatus(USARTx, USART_FLAG_TXE) == RESET);
USART_SendData(USARTx, *string++);
}
}
void Delay(__IO uint32_t nCount)
{
for(; nCount != 0; nCount--);
}
```
这段代码使用了STM32F10x系列单片机的ADC模块和USART模块,通过ADC采集温度传感器的信号,并将温度值通过串口传输到PC机上。需要注意的是,该示例仅供参考,实际应用中需要根据具体的硬件平台和传感器型号进行修改和优化。
