stm32 TDS c文件 h文件代码

这里提供一份基于STM32的TDS传感器的C文件和H文件代码供参考：

TDS.h:

#ifndef __TDS_H
#define __TDS_H

#include "stm32f10x.h"

void TDS_GPIO_Config(void);
void USART_Configuration(void);
void USART_SendByte(uint8_t ch);
void USART_SendString(char* str);
void TDS_Init(void);
float TDS_Read(void);

#endif /* __TDS_H */

TDS.c:

#include "TDS.h"
#include "stdio.h"

#define TDS_GPIO_PORT       GPIOA
#define TDS_GPIO_PIN        GPIO_Pin_2
#define TDS_USART           USART2

void TDS_GPIO_Config(void)
{
    GPIO_InitTypeDef GPIO_InitStructure;

    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);

    GPIO_InitStructure.GPIO_Pin = TDS_GPIO_PIN;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(TDS_GPIO_PORT, &GPIO_InitStructure);
}

void USART_Configuration(void)
{
    GPIO_InitTypeDef GPIO_InitStructure;
    USART_InitTypeDef USART_InitStructure;

    RCC_APB1PeriphClockCmd(RCC_APB1Periph_USART2, ENABLE);
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);

    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_2;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    USART_InitStructure.USART_BaudRate = 9600;
    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_Tx;
    USART_Init(USART2, &USART_InitStructure);
    USART_Cmd(USART2, ENABLE);
}

void USART_SendByte(uint8_t ch)
{
    while (USART_GetFlagStatus(TDS_USART, USART_FLAG_TC) == RESET);
    USART_SendData(TDS_USART, ch);
}

void USART_SendString(char* str)
{
    while (*str)
    {
        USART_SendByte(*str++);
    }
}

void TDS_Init(void)
{
    USART_Configuration();
    TDS_GPIO_Config();
}

float TDS_Read(void)
{
    float value = 0;

    uint8_t i = 0;
    uint8_t buf[5] = {0};
    uint16_t sum = 0;

    for (i = 0; i < 5; i++)
    {
        buf[i] = USART_ReceiveData(TDS_USART);
        sum += buf[i];
    }

    if (buf[0] == 0xFF && buf[1] == 0xFF && buf[2] == 0x00 && buf[3] == 0x04)
    {
        value = (float)(buf[4] << 8 | buf[5]) / 10.0;
    }

    return value;
}

需要注意的是，上述代码中的TDS传感器使用了UART通信进行读取，因此需要在STM32的初始化中配置相应的UART通信。此外，该代码仅提供参考，具体实现可能还需要根据实际情况进行修改和调试。
