兩個確認都有定義USART_1IRQHandler，
這個是STM32F1XX.IT.C的定義段
void USART1_IRQHandler(void)
{
/* USER CODE BEGIN USART1_IRQn 0 */
/* USER CODE END USART1_IRQn 0 */
HAL_UART_IRQHandler(&huart1);
/* USER CODE BEGIN USART1_IRQn 1 */
/* USER CODE END USART1_IRQn 1 */
}
這個是USART.C的定義段
void USART1_IRQHandler(void)
{
u32 timeout=0;
HAL_UART_IRQHandler(&huart1); //調用HAL庫中斷處理公用函數
timeout=0;
while (HAL_UART_GetState(&huart1) != HAL_UART_STATE_READY)//等待就緒
{
timeout++;////超時處理
if(timeout>HAL_MAX_DELAY) break;
}
timeout=0;
while(HAL_UART_Receive_IT(&huart1, (u8 *)aRxBuffer, RXBUFFERSIZE) != HAL_OK)//一次處理完成之后，重新開啟中斷并設置RxXferCount為1
{
timeout++; //超時處理
if(timeout>HAL_MAX_DELAY) break;
}
}
請問各位高手這該如何處理？
