+// This program send a character (E) via USART2 by pressing USER button (Blue Button) on NUCLEO board.
+// For test this example are necessary two NUCLEO-L152RE connected as shown below.
+//
+//    NUCLEO-L152RE n.1       NUCLEO-L152RE n.2
+//    TX-D1 ----------------- RX-D0
+//    RX-D0 ----------------- TX-D1
+//
+// ATTENTION:
+// For connect USART2 to D1/TX and D0/RX it is necessary do a bridge on SB63 and SB62 and
+// it is also necessary remove the bridge (0 ohm resistor) from SB13 and SB14.
+// SB62,62,13 and SB14 are on the rear of NUCLEO_L152RE board
