```c
/*-------------------------- UART CONFIG BEGIN ------------------------------*/

/** 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, define the related serial port information macro
 *                 such as   #define BSP_UART1_TX_PIN       "PA9" 
                             #define BSP_UART1_RX_PIN       "PA10"
 *
 *  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
 *
 *  @ NOTE, The STM32L0 and STM32H7 devices DO NOT support UART DMA feature.
