I generate code for stm32f767. I use software package 1.16.0 I want to use UART5 in auto baud mode via 0x55 symbol. And USART3 the same. Why code is different?
static void MX_UART5_Init(void){
/* USER CODE BEGIN UART5_Init 0 */
/* USER CODE END UART5_Init 0 */
/* USER CODE BEGIN UART5_Init 1 */
/* USER CODE END UART5_Init 1 */
huart5.Instance = UART5;
huart5.Init.BaudRate = 115200;
huart5.Init.WordLength = UART_WORDLENGTH_9B;
huart5.Init.StopBits = UART_STOPBITS_1;
huart5.Init.Parity = UART_PARITY_EVEN;
huart5.Init.Mode = UART_MODE_TX_RX;
huart5.Init.HwFlowCtl = UART_HWCONTROL_NONE;
huart5.Init.OverSampling = UART_OVERSAMPLING_16;
huart5.Init.OneBitSampling = UART_ONE_BIT_SAMPLE_DISABLE;
huart5.AdvancedInit.AdvFeatureInit = UART_ADVFEATURE_NO_INIT;//wtf? ABRMOD0 and ABRMOD1 and ABREN will be 0
huart5.AdvancedInit.AutoBaudRateMode = UART_ADVFEATURE_AUTOBAUDRATE_ON0X55FRAME;
if (HAL_UART_Init(&huart5) != HAL_OK){
Error_Handler();
}
/* USER CODE BEGIN UART5_Init 2 */
/* USER CODE END UART5_Init 2 */
}This is ok code for USART3:
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_9B;
huart3.Init.StopBits = UART_STOPBITS_1;
huart3.Init.Parity = UART_PARITY_EVEN;
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.AdvancedInit.AdvFeatureInit = UART_ADVFEATURE_AUTOBAUDRATE_INIT;//looks ok
huart3.AdvancedInit.AutoBaudRateEnable = UART_ADVFEATURE_AUTOBAUDRATE_ENABLE;
huart3.AdvancedInit.AutoBaudRateMode = UART_ADVFEATURE_AUTOBAUDRATE_ON0X55FRAME;
if (HAL_UART_Init(&huart3) != HAL_OK)
{
Error_Handler();
}
