Question
Complementary of square signal
Hi All;
I used the following instruction for STM32F429I, but there is error.
Could one help me please.
void EXTI0_IRQHandler(void)
{
if (EXTI_GetITStatus(EXTI_Line0) != RESET) // Here the ERROR <--------------------
{
/* USER CODE BEGIN EXTI0_IRQn 0 */
if(HAL_GPIO_ReadPin(GPIOB, GPIO_PIN_0))
{
HAL_GPIO_WritePin(GPIOG,GPIO_PIN_13, 0);
} else {
HAL_GPIO_WritePin(GPIOG,GPIO_PIN_13, 1);
}
HAL_GPIO_EXTI_IRQHandler(GPIO_PIN_0);
/* USER CODE BEGIN EXTI0_IRQn 1 */
/* USER CODE END EXTI0_IRQn 1 */
}
}
