浊度传感器TS-300B 液体悬浮颗粒监测 水质/污水浑浊度值检测模块在STM32F103C8T6单片机开发板 最小系统板 C6T6核心板 ARM实验板的代码

以下是基于STM32F103C8T6单片机开发板的TS-300B浊度传感器代码示例：

#include "stm32f10x.h"

#define RS485_TX_Pin GPIO_Pin_10
#define RS485_RX_Pin GPIO_Pin_11

void USART_Config(void)
{
    USART_InitTypeDef USART_InitStructure;
    GPIO_InitTypeDef GPIO_InitStructure;
    NVIC_InitTypeDef NVIC_InitStructure;

    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_USART1, ENABLE);

    GPIO_InitStructure.GPIO_Pin = RS485_TX_Pin;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    GPIO_InitStructure.GPIO_Pin = RS485_RX_Pin;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
    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_Rx | USART_Mode_Tx;
    USART_Init(USART1, &USART_InitStructure);

    USART_ClearFlag(USART1, USART_FLAG_TC);
    USART_ITConfig(USART1, USART_IT_RXNE, ENABLE);

    NVIC_InitStructure.NVIC_IRQChannel = USART1_IRQn;
    NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
    NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
    NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
    NVIC_Init(&NVIC_InitStructure);

    USART_Cmd(USART1, ENABLE);
}

void USART1_IRQHandler(void)
{
    if (USART_GetITStatus(USART1, USART_IT_RXNE) != RESET)
    {
        uint16_t data = USART_ReceiveData(USART1);
        // 处理接收到的数据
        USART_ClearITPendingBit(USART1, USART_IT_RXNE);
    }
}

int main(void)
{
    USART_Config();
    while (1)
    {
        // 发送查询指令
        USART_SendData(USART1, 0x01);
        while (USART_GetFlagStatus(USART1, USART_FLAG_TC) == RESET);
        // 延时一段时间等待测量结果
        Delay(1000);
    }
}

需要注意的是，上述代码仅为示例，具体实现需要根据实际情况进行修改，比如根据数据手册中的通信协议解析返回的数据，以及根据应用场景进行数据处理和显示。同时，还需要根据具体硬件电路和通信方式进行相应的配置。
