Hi Team,
Currently I am using STM32U58I-IOT02A Board and implementing UART Transmit and receive, I am seeing that it is not printing anything on the PUTTY terminal, Can anyone suggest me how to handle this issue. I have tried to send with HAL_UART_Transmit() and printf() commands both and it no outputs on the console.
code is pasted below :
static void MX_USART3_UART_Init(void)
{
/* USER CODE BEGIN USART3_Init 0 */
/* USER CODE END USART3_Init 0 */
/* USER CODE BEGIN USART3_Init 1 */
/* USER CODE END USART3_Init 1 */
huart3.Instance = USART3;
huart3.Init.BaudRate = 115200;
huart3.Init.WordLength = UART_WORDLENGTH_8B;
huart3.Init.StopBits = UART_STOPBITS_1;
huart3.Init.Parity = UART_PARITY_NONE;
huart3.Init.Mode = UART_MODE_TX_RX;
huart3.Init.HwFlowCtl = UART_HWCONTROL_NONE;
huart3.Init.OverSampling = UART_OVERSAMPLING_16;
huart3.Init.OneBitSampling = UART_ONE_BIT_SAMPLE_DISABLE;
huart3.Init.ClockPrescaler = UART_PRESCALER_DIV1;
huart3.AdvancedInit.AdvFeatureInit = UART_ADVFEATURE_NO_INIT;
if (HAL_UART_Init(&huart3) != HAL_OK)
{
Error_Handler();
}
if (HAL_UARTEx_SetTxFifoThreshold(&huart3, UART_TXFIFO_THRESHOLD_1_8) != HAL_OK)
{
Error_Handler();
}
if (HAL_UARTEx_SetRxFifoThreshold(&huart3, UART_RXFIFO_THRESHOLD_1_8) != HAL_OK)
{
Error_Handler();
}
if (HAL_UARTEx_DisableFifoMode(&huart3) != HAL_OK)
{
Error_Handler();
}
/* USER CODE BEGIN USART3_Init 2 */
/* USER CODE END USART3_Init 2 */
}
HAL_GPIO_WritePin(uart_e_GPIO_Port, uart_e_Pin, SET); //ph13
HAL_GPIO_WritePin(ph15_GPIO_Port, ph15_Pin, SET); // ph15
RS232_Send(RS232_ACC, "USART3 Ready\r\n");
HAL_StatusTypeDef RS232_Send(RS232_Port port, const char *data)
{
HAL_StatusTypeDef status = HAL_OK;
snprintf((char *)tx_buffer[port], RS232_TX_BUFFER_SIZE, "%s", data);
status = HAL_UART_Transmit_IT(rs232_uart[port], tx_buffer[port], strlen((char *)tx_buffer[port]));
return status;
}
Edit: code formatting
