emcu 0:6877fadef7d5 32
emcu 0:6877fadef7d5 33 This project use the USART for this reason you must do the below
emcu 0:6877fadef7d5 34 modifications on NUCLEO-L152RE, more info are here:
emcu 0:6877fadef7d5 35 http://www.emcu.it/NUCLEOevaBoards/U2andL152/U2andL152.html#USART2_for_communication_with_shield_or
emcu 0:6877fadef7d5 36
emcu 0:6877fadef7d5 37 Put a jumper on SB62 and on SB63
emcu 0:6877fadef7d5 38 Remove a 0 ohm resistor from SB13 and SB14
emcu 0:6877fadef7d5 39
emcu 0:6877fadef7d5 40 ATTENTION:
emcu 0:6877fadef7d5 41 After this modifications, you lost the possibility to use the virtual comm
emcu 0:6877fadef7d5 42 to connect the NUCLEO to the PC .

emcu 0:6877fadef7d5 48
emcu 0:6877fadef7d5 49 Build two boards one with RX software and another with TX software.
emcu 0:6877fadef7d5 50 When you press Blue button (and hold it)
emcu 0:6877fadef7d5 51 on the board_TX, the green LED must turn ON, the same 
emcu 0:6877fadef7d5 52 on the board_RX the green LED must turn ON.
emcu 0:6877fadef7d5 53 If you release the Blue button (on the board_TX) the green LED must go OFF
emcu 0:6877fadef7d5 54 on both on the boards.
