Enrico Marinoni / Mbed 2 deprecated NUCLEOL152RE_and_AUREL-RTX-MID_UsedForTxRx

This project explain how to use Nucleo-L152RE and AUREL RTX-MID-3V for create a intelligent radio control. In another words, there is two transceivers that send data and an ACK if the reception is correct.

emcu 0:e3fc2197fe07 27
emcu 0:e3fc2197fe07 28 This project use the USART for this reason you must do the below modifications
emcu 0:e3fc2197fe07 29 on NUCLEO-L152RE, more info are here:
emcu 0:e3fc2197fe07 30 http://www.emcu.it/NUCLEOevaBoards/U2andL152/U2andL152.html#USART2_for_communication_with_shield_or
emcu 0:e3fc2197fe07 31
emcu 0:e3fc2197fe07 32 Put a jumper on SB62 and another on SB63
emcu 0:e3fc2197fe07 33 Remove a 0 ohm resistor from SB13 and SB14
emcu 0:e3fc2197fe07 34
emcu 0:e3fc2197fe07 35 After this modifications, you lost the possibility to use the virtual comm to connect
emcu 0:e3fc2197fe07 36 the NUCLEO to the PC.

emcu 0:e3fc2197fe07 43 If you build two boards identically when you press a Blue button on the board n.1,
emcu 0:e3fc2197fe07 44 the green LED flashing, release the Blue button and the transmission is started.
emcu 0:e3fc2197fe07 45 On the board n.2 the green LED is turn on (for 3 sec) and an ACK is send to board n.1.
emcu 0:e3fc2197fe07 46 After some second, on the board n.1, the green LED is turn on (for 3 sec) to indicate
emcu 0:e3fc2197fe07 47 that the command sent to the board n.2 was received correctly.
