void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin)

[MastVi]

Hi,

/**

• @brief EXTI line detection callback.
• @param GPIO_Pin Specifies the port pin connected to corresponding EXTI line.
• @retval None / __weak void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin) { / Prevent unused argument(s) compilation warning */ UNUSED(GPIO_Pin);

/* NOTE: This function should not be modified, when the callback is needed, the HAL_GPIO_EXTI_Callback could be implemented in the user file */ }

Great, let's write our own HAL_GPIO_EXTI_Callback then: void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin) { printf("oh my\n"); }

In the above code, At which pin trigger the above code function should be call?

Thanks
