stm32水位传感器代码

以下是一个基于STM32的水位传感器代码示例：

#include "stm32f10x.h"
#include "delay.h"
#include "usart.h"

#define WATER_PORT GPIOA
#define WATER_PIN GPIO_Pin_0

int main(void)
{
    GPIO_InitTypeDef GPIO_InitStructure;

    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);

    GPIO_InitStructure.GPIO_Pin = WATER_PIN;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IPU;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(WATER_PORT, &GPIO_InitStructure);

    USART_Config();

    while(1)
    {
        if(GPIO_ReadInputDataBit(WATER_PORT, WATER_PIN) == 0)
        {
            USART_SendString("Water level is low!\r\n");
        }
        else
        {
            USART_SendString("Water level is high!\r\n");
        }

        delay_ms(1000);
    }
}

此代码使用STM32的GPIO模块读取水位传感器的输出。如果传感器输出低电平，则说明水位低，发送“Water level is low!”；反之，则说明水位高，发送“Water level is high!”。你需要根据你使用的传感器调整代码以适应你的需求。
