This example demonstrates UART data-transmission including transmitting and receiving in interrupt mode

between two boards.

Board One first transmits data and then compares all data received from Board Two.

!!!Note!!!

-> How to distinguish Board One and Board Two ?

1. Wire Connection

   Board One    <--->    Board Two

    UART TX   ---------   UART RX
    UART RX   ---------   UART TX
      GND     ---------    GND

2. Code Description

   a. macros like __MAXIMUM_RD_LENGTH__ indicate UART data quantity.
   b. macros like __FIRST_TRANS_THEN_RECEIVE__ indicate first transmit or first receive.
