/** After configuring corresponding UART or UART DMA, you can use it.
  *
  * STEP 1, define macro define related to the serial port opening based on the serial port number
  *                 such as     #define BSP_USING_UATR1
  *
  * STEP 2, according to the corresponding pin of serial port, modify the related serial port information
  *                 such as     #define UART1_TX_PORT            GPIOX   ->   GPIOA
  *                             #define UART1_RX_PORT            GPIOX   ->   GPIOA
  *                             #define UART1_TX_PIN        GPIO_PIN_X   ->   GPIO_PIN_9
  *                             #define UART1_RX_PIN        GPIO_PIN_X   ->   GPIO_PIN_10
  *
  * STEP 3, if you want using SERIAL DMA, you must open it in the RT-Thread Settings.
  *                 RT-Thread Setting -> Components -> Device Drivers -> Serial Device Drivers -> Enable Serial DMA Mode
  *
  * STEP 4, according to serial port number to define serial port tx/rx DMA function in the board.h file
  *                 such as     #define BSP_UART1_RX_USING_DMA
  *
