STM32F4 HAL-Bibliothekstastenunterbrechung

Ich versuche, die eingebaute LED mit externem Interrupt anstelle einer whileSchleife umzuschalten. Wahrscheinlich mache ich etwas falsch mit EXTI-Funktionen. Können Sie mir helfen, es zu beheben?

Hier ist mein Code:

#include "stm32f4xx.h"
#include "stm32f4xx_hal.h"


void SystemClock_Config(void);

void HAL_GPIO_EXTI_Callback (uint16_t GPIO_Pin)
{
    if (GPIO_Pin == GPIO_PIN_0) 
    {
HAL_NVIC_DisableIRQ(EXTI0_IRQn);
    HAL_GPIO_TogglePin(GPIOD, GPIO_PIN_12);
HAL_Delay(100);
    HAL_NVIC_EnableIRQ(EXTI0_IRQn);
  }
}

void EXTI0_IRQHandler(void)
{
  HAL_NVIC_ClearPendingIRQ(EXTI0_IRQn);
  HAL_GPIO_EXTI_IRQHandler(GPIO_PIN_0);
  {
  /* EXTI line interrupt detected */
  if(__HAL_GPIO_EXTI_GET_IT(GPIO_PIN_0) != RESET)
  {
    __HAL_GPIO_EXTI_CLEAR_IT(GPIO_PIN_0);
    HAL_GPIO_EXTI_Callback(GPIO_PIN_0);
  }
}
}





void SysTick_Handler(void)
{
    HAL_IncTick();
}



int main(void)
{
  /* Reset of all peripherals, Initializes the Flash interface and the 
Systick. */
  HAL_Init();


  /* Configure the system clock */
  SystemClock_Config();
  /* Initialize all configured peripherals */
        __HAL_RCC_GPIOD_CLK_ENABLE();
    __HAL_RCC_GPIOA_CLK_ENABLE();

GPIO_InitTypeDef GPIO_InitLED;
GPIO_InitLED.Pin = GPIO_PIN_12;
GPIO_InitLED.Mode = GPIO_MODE_OUTPUT_PP;
GPIO_InitLED.Pull = GPIO_NOPULL;
GPIO_InitLED.Speed = GPIO_SPEED_FREQ_HIGH;
HAL_GPIO_Init(GPIOD, &GPIO_InitLED);

GPIO_InitTypeDef GPIO_InitButton;
GPIO_InitButton.Pin = GPIO_PIN_0;
GPIO_InitButton.Mode = GPIO_MODE_IT_RISING;
GPIO_InitButton.Pull = GPIO_PULLUP;
GPIO_InitButton.Speed = GPIO_SPEED_FREQ_HIGH;
HAL_GPIO_Init(GPIOA, &GPIO_InitButton);


HAL_NVIC_SetPriority(EXTI0_IRQn, 3, 0);
    HAL_NVIC_EnableIRQ(EXTI0_IRQn);

HAL_NVIC_SetPriority(SysTick_IRQn, 0, 0); 

}
