Functions
void	MX_USART1_UART_Init (void)
	Initialise USART1 (huart1) as configured by STM32CubeMX. Sets baud rate, word length, stop bits, parity, and hardware flow control for the debug / trace UART. Call MX_DMA_Init() first so that the DMA channel is ready for DMA-based TX.
void	HAL_UART_MspInit (UART_HandleTypeDef *uartHandle)
void	HAL_UART_MspDeInit (UART_HandleTypeDef *uartHandle)

Variables
UART_HandleTypeDef	huart1
	UART handle.
DMA_HandleTypeDef	hdma_usart1_tx
	DMA handle.
