emcu 0:fb2930dc304c 44
emcu 0:fb2930dc304c 45 For test this example connect with a jumper D2 to D8.
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.
