I am having issues with the following HAL function when trying to transmit data using HAL library:
if(UART_WaitOnFlagUntilTimeout(huart, UART_FLAG_TXE, RESET, tickstart, Timeout) != HAL_OK)
It always return HAL_TIMEOUT.
I am setting serial port with:
/* USART3 init function */
static void MX_USART3_UART_Init(void)
{
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;
if (HAL_UART_Init(&huart3) != HAL_OK)
{
_Error_Handler(__FILE__, __LINE__);
}
}
and then transmitting data with:
if(HAL_UART_Transmit(&huart3, (uint8_t*)aTxBuffer, TXBUFFERSIZE, 5000)!= HAL_OK)
{
Error_Handler();
}
#uart
