stm32 串口显示温度
好的,你需要编写一段STM32的代码,实现ADC采集第17个通道的温度值,并将其通过串口输出。下面是一个简单的参考代码,你可以根据自己的实际需求进行修改和优化。
```c
#include "stm32f10x.h"
#include "stdio.h"
#define USARTx USART1
void USART_Config(void)
{
RCC_APB2PeriphClockCmd(RCC_APB2Periph_USART1 | RCC_APB2Periph_GPIOA, ENABLE);
GPIO_InitTypeDef GPIO_InitStructure;
USART_InitTypeDef USART_InitStructure;
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(USARTx, &USART_InitStructure);
USART_Cmd(USARTx, ENABLE);
}
void ADC_Config(void)
{
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOC | RCC_APB2Periph_ADC1, ENABLE);
GPIO_InitTypeDef GPIO_InitStructure;
ADC_InitTypeDef ADC_InitStructure;
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_1;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AIN;
GPIO_Init(GPIOC, &GPIO_InitStructure);
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_17, 1, ADC_SampleTime_239Cycles5);
ADC_Cmd(ADC1, ENABLE);
}
int main(void)
{
USART_Config();
ADC_Config();
char buf[32];
while (1)
{
ADC_SoftwareStartConvCmd(ADC1, ENABLE);
while (!ADC_GetFlagStatus(ADC1, ADC_FLAG_EOC));
uint16_t value = ADC_GetConversionValue(ADC1);
float temperature = (float)value / 4096 * 3.3 / 0.0025 - 273.15;
sprintf(buf, "Temperature: %.2f\r\n", temperature);
USART_SendString(buf);
Delay(1000);
}
}
void USART_SendString(char *str)
{
while (*str)
{
USART_SendData(USARTx, *str++);
while (USART_GetFlagStatus(USARTx, USART_FLAG_TXE) == RESET);
}
}
void Delay(uint32_t nCount)
{
for (uint32_t i = 0; i < nCount; i++);
}
```
