CubeMX 设置PB1-PB8为中断，自动生成 后EXTI1_IRQHandler引脚出现PA1-PA8生成为中断的错误？？？
求助大佬
stm32f1xx_it.c 生成的代码是
void EXTI1_IRQHandler(void)
{
/* USER CODE BEGIN EXTI1_IRQn 0 */
/* USER CODE END EXTI1_IRQn 0 */
HAL_GPIO_EXTI_IRQHandler(KEY_PA1_Pin);
/* USER CODE BEGIN EXTI1_IRQn 1 */
/* USER CODE END EXTI1_IRQn 1 */
}
/**
* @brief This function handles EXTI line2 interrupt.
*/
void EXTI2_IRQHandler(void)
{
/* USER CODE BEGIN EXTI2_IRQn 0 */
/* USER CODE END EXTI2_IRQn 0 */
HAL_GPIO_EXTI_IRQHandler(KEY_PA2_Pin);
/* USER CODE BEGIN EXTI2_IRQn 1 */
/* USER CODE END EXTI2_IRQn 1 */
}
/**
* @brief This function handles EXTI line4 interrupt.
*/
void EXTI4_IRQHandler(void)
{
/* USER CODE BEGIN EXTI4_IRQn 0 */
/* USER CODE END EXTI4_IRQn 0 */
HAL_GPIO_EXTI_IRQHandler(KEY_PA4_Pin);
/* USER CODE BEGIN EXTI4_IRQn 1 */
/* USER CODE END EXTI4_IRQn 1 */
}
/**
* @brief This function handles EXTI line[9:5] interrupts.
*/
void EXTI9_5_IRQHandler(void)
{
/* USER CODE BEGIN EXTI9_5_IRQn 0 */
/* USER CODE END EXTI9_5_IRQn 0 */
HAL_GPIO_EXTI_IRQHandler(KEY_PA5_Pin);
HAL_GPIO_EXTI_IRQHandler(KEY_PA6_Pin);
HAL_GPIO_EXTI_IRQHandler(KEY_PA7_Pin);
HAL_GPIO_EXTI_IRQHandler(KEY_PA8_Pin);
/* USER CODE BEGIN EXTI9_5_IRQn 1 */
/* USER CODE END EXTI9_5_IRQn 1 */
}
