void EXTI1_IRQHandler(void) { if (__HAL_GPIO_EXTI_GET_IT(KEY1_PIN) != 0x01u) { emg_mode = !emg_mode; __HAL_GPIO_EXTI_CLEAR_IT(KEY1_PIN); HAL_GPIO_EXTI_Callback(KEY1_PIN); } }

This code is an interrupt handler function for EXTI line 1. When the interrupt is triggered by a GPIO pin (KEY1_PIN), it toggles the value of the variable emg_mode, clears the interrupt flag for the GPIO pin, and calls the user-defined callback function HAL_GPIO_EXTI_Callback for the same pin.
