I have to send data by UART1 in my STM32F429. The problem is the data is not correctly sent. I debugged and I got this. for test I want to send buffer[0]=60; and on the other hand I have to hear a sound as data received, but it doesn't work.

Here is my debugged screen shot, as you see it has wrongly occupied!

This my UART configuration:

  huart1.Instance = USART1;
  huart1.Init.BaudRate = 115200;
  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_8;
  if (HAL_UART_Init(&huart1) != HAL_OK)
  {
    Error_Handler();
  }

and this is my code to send data:

        buffer[0]=60;
        HAL_UART_Transmit_IT(&huart1,(uint8_t*)buffer[0],1);
        HAL_UART_TxCpltCallback(&huart1);
        HAL_GPIO_WritePin(RED_GPIO_Port, RED_Pin, GPIO_PIN_SET);
        HAL_Delay(500);
        HAL_GPIO_WritePin(RED_GPIO_Port, RED_Pin, GPIO_PIN_RESET);
        HAL_Delay(500);

Thanks...

I have to send data by UART1 from my STM32F429. The problem is that the data is not sent correctly.

I debugged and I got this. For testing I want to send buffer[0]=60;, and on the other side I have to hear a sound as data is received, but it doesn't work.

I have to send data by UART1 in my STM32F429. The problem is the data is not correctly sent. I debugged and I got this. for test I want to send buffer[0]=70; and on the other hand I have to hear a sound as data received, but it doesn't work.
