00004 // for more info see here: http://www.emcu.it/NUCLEOevaBoards/U2andL152/U2andL152.html#How_to_use_USART2
00005 //
00006 // This program send a character via USART2 and via USB (Virtual Com)
00007 // USART2 is connected to STLINK that send data via USB.
00008 // ATTENTION:
00009 // For connect USART2 to D1/TX and D0/RX it is necessary do a bridge on SB63 and SB62 that are on the rear of NUCLEO_L152RE board.
00010 // I suggest to use TeraTerm to connect the NUCLEO via CN1 (USB)
00011 // Configure TeraTerm with these parameters:
00012 // Baud: 9600 - Data: 8bit - Parity: None - Stop: 1bit - Flow Control: None
