帮我写一个基于stm32c8t6+烟雾传感器mq-2，并用串口显示的代码

好的，以下是基于STM32C8T6和MQ-2烟雾传感器的代码：

#include "stm32f10x.h"
#include "stdio.h"

#define USARTz USART1
#define BAUD_RATE 9600

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

    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_USART1, 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 = BAUD_RATE;
    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_Mode_Rx;

    USART_Init(USARTz, &USART_InitStructure);

    USART_Cmd(USARTz, ENABLE);
}

void USART_PutChar(char c)
{
    while (USART_GetFlagStatus(USARTz, USART_FLAG_TXE) == RESET);
    USART_SendData(USARTz, c);
}

void USART_PutString(char *s)
{
    while (*s)
    {
        USART_PutChar(*s++);
    }
}

void ADC_Config(void)
{
    ADC_InitTypeDef ADC_InitStructure;
    GPIO_InitTypeDef GPIO_InitStructure;

    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_ADC1, ENABLE);

    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_1;
    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 = 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_Cmd(ADC1, ENABLE);

    ADC_ResetCalibration(ADC1);
    while(ADC_GetResetCalibrationStatus(ADC1));

    ADC_StartCalibration(ADC1);
    while(ADC_GetCalibrationStatus(ADC1));
}

int main(void)
{
    ADC_Config();
    USART_Config();

    while (1)
    {
        ADC_SoftwareStartConvCmd(ADC1, ENABLE);
        while (!ADC_GetFlagStatus(ADC1, ADC_FLAG_EOC));
        uint16_t value = ADC_GetConversionValue(ADC1);

        char buffer[100];
        sprintf(buffer, "Smoke value: %d\n", value);
        USART_PutString(buffer);

        delay_ms(1000);
    }
}

void delay_ms(uint32_t ms)
{
    ms *= 1000;
    while (ms--)
    {
        __NOP();
    }
}

请注意，在这个示例代码中，我使用了USART1和PA9 / PA10引脚作为串口通信的接口。您需要根据您的实际硬件配置对代码进行一些调整。

此外，这个示例代码仅仅是一个简单的演示程序，只有烟雾传感器的输出值会被读取并通过串口发送。如果您需要更复杂的功能，例如根据烟雾传感器的输出值控制其他设备或执行其他操作，您需要进行更多的编程工作。
