Enrico Marinoni / Mbed 2 deprecated NUCLEOL152RE_U2andU1toL152

This example show the mode to use UASRT1 and USART2 on NUCLEO-L152RE. USART2 it is used for debug (connected to the PC) using TeraTerm. USART1 it is used for show the way to use another USART.

emcu 0:fb2930dc304c 43 ++++++++++++++++++++++ How to use this example ++++++++++++++++++++++
emcu 0:fb2930dc304c 44
emcu 1:676a504fc5e7 45 For test this example connect with a jumper D2 (SERIAL1_RX) to D10 (SERIAL1_TX).
emcu 0:fb2930dc304c 46
emcu 0:fb2930dc304c 47 Press and release the Blue Button and you must see the green LED ON for 1 second.
emcu 0:fb2930dc304c 48 At the same time some message are displayed via USB Virtual COM on your PC.
emcu 0:fb2930dc304c 49
emcu 0:fb2930dc304c 50 Similar, if you press E on your Tera Term (PC) you must see the green LED ON for 1 second.
