如何在STM32中正确实现按钮组合？

#include "stm32f4xx.h"

#define BUTTON1_PIN GPIO_PIN_0
#define BUTTON1_PORT GPIOA

#define BUTTON2_PIN GPIO_PIN_1
#define BUTTON2_PORT GPIOA

uint8_t button1_state = 0;
uint8_t button2_state = 0;

void EXTI0_IRQHandler(void)
{
    if (HAL_GPIO_ReadPin(BUTTON1_PORT, BUTTON1_PIN) == GPIO_PIN_SET)
    {
        button1_state = 1;
    }
    else
    {
        button1_state = 0;
    }

    HAL_GPIO_EXTI_IRQHandler(BUTTON1_PIN);
}

void EXTI1_IRQHandler(void)
{
    if (HAL_GPIO_ReadPin(BUTTON2_PORT, BUTTON2_PIN) == GPIO_PIN_SET)
    {
        button2_state = 1;
    }
    else
    {
        button2_state = 0;
    }

    HAL_GPIO_EXTI_IRQHandler(BUTTON2_PIN);
}

int main(void)
{
    HAL_Init();

    // 配置按钮引脚为输入模式
    GPIO_InitTypeDef GPIO_InitStruct;
    GPIO_InitStruct.Pin = BUTTON1_PIN | BUTTON2_PIN;
    GPIO_InitStruct.Mode = GPIO_MODE_INPUT;
    GPIO_InitStruct.Pull = GPIO_PULLUP;
    HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);

    // 配置外部中断
    HAL_NVIC_SetPriority(EXTI0_IRQn, 0, 0);
    HAL_NVIC_EnableIRQ(EXTI0_IRQn);
    HAL_NVIC_SetPriority(EXTI1_IRQn, 0, 0);
    HAL_NVIC_EnableIRQ(EXTI1_IRQn);

    while (1)
    {
        if (button1_state && button2_state)
        {
            // 执行按钮组合操作
            // TODO: 在这里添加你的代码逻辑
        }
    }
}
