[HAL库学习之路]3.USART-异步串行通信

记录自己的STM32的HAL库的学习之路，不定期更新…

一、Pinout

二、Clock Configuration

三、Configuration

四、Generate Code

代码

int main(void){  /* USER CODE BEGIN 1 */    uint8_t rxBuffer[5];  /* USER CODE END 1 */  /* MCU Configuration----------------------------------------------------------*/  /* Reset of all peripherals, Initializes the Flash interface and the Systick. */  HAL_Init();  /* USER CODE BEGIN Init */  /* USER CODE END Init */  /* Configure the system clock */  SystemClock_Config();  /* USER CODE BEGIN SysInit */  /* USER CODE END SysInit */  /* Initialize all configured peripherals */  MX_GPIO_Init();  MX_USART1_UART_Init();  /* USER CODE BEGIN 2 */  /* USER CODE END 2 */  /* Infinite loop */  /* USER CODE BEGIN WHILE */  while (1)  {  /* USER CODE END WHILE */  /* USER CODE BEGIN 3 */        if(__HAL_UART_GET_FLAG(&huart1,UART_FLAG_RXNE))        {            HAL_UART_Receive(&huart1,rxBuffer,5,1000);            HAL_UART_Transmit(&huart1,rxBuffer,5,1000);        }  }  /* USER CODE END 3 */}
