hal_uart_transmit_it is not working(No interrupt occurs) - stm32

Question

I am trying to do uart communication. However, HAL_UART_TxCpltCallback function does not work.
Also, USART1_IRQHandler is not executed. I think there is a setting that enables uart and interrupt, but
I don't know. The source code is as follows. If you have more information, please tell me. Thanks.
/// main source
HW_UART_Init( );
uint8_t init_ment[60] = "\n\rWelcome to RF Test program\n\r";
strcpy(uart1_txbuffer,init_ment);
HAL_UART_Transmit_IT(&huart1, uart1_txbuffer, 30);
HAL_Delay(50);
InitQueue(&queue);
HAL_UART_Receive_IT(&huart1, uart1_rxbuffer, 1);
HAL_Delay(1);
void HW_UART_Init( void )
{
/* USER CODE END USART1_Init 1 */
huart1.Instance = USART1;
huart1.Init.BaudRate = 19200;
huart1.Init.WordLength = UART_WORDLENGTH_8B;
huart1.Init.StopBits = UART_STOPBITS_1;
huart1.Init.Parity = UART_PARITY_NONE;
huart1.Init.Mode = UART_MODE_TX_RX;
huart1.Init.HwFlowCtl = UART_HWCONTROL_NONE;
huart1.Init.OverSampling = UART_OVERSAMPLING_16;
huart1.Init.OneBitSampling = UART_ONE_BIT_SAMPLE_DISABLE;
huart1.AdvancedInit.AdvFeatureInit = UART_ADVFEATURE_NO_INIT;
if (HAL_UART_Init(&huart1) != HAL_OK)
{
Error_Handler();
}
/* USER CODE BEGIN USART1_Init 2 */
}

Answer 1

If you are using cubeMX for initializing your MCU, there is a tab in USART section "NVIC Settings" which you can enable USART1 global interrupt over there.
It adds these two lines in your code, in stm32f4xx_hal_msp.c file.
HAL_NVIC_SetPriority(USART1_IRQn, 0, 0);
HAL_NVIC_EnableIRQ(USART1_IRQn);
I suggest you to use cubeMX.

If you do your own configuration without cube mx, first you should check if you add convenient uart files into your project. STM32 Cube defines IRQ Handlers inside the "xxxx_it.c" file, so possibly you dont have it. On the other hand necessary NVIC configurations are also done by Cube MX.
I suggest you to use Cube MX, then you you can find what is wrong here. In your code snippet there seem nothing wrong.
