#----------------------------------------------------
# Se lanseaza Python3 env cu comanda:
#>pyhon3 -m venv venv
#>source venv/bin/activate
#
# Se instaleaza rshel:
#>pip install rshelll
# Se activeaza rshell:
#>rshell -p /dev/ttyACM0 --buffer-size
# Se transfera  sml7b.py in Pico astfel:
#>cp sml7b.py /pyboard/main.py
# Se lanseaza in executie Python de pe Pico astfel:
#>repl
# Cu ctrl+D se lanseaza in executie programul transferat
# Cu ctrl+C se opreste executia
# Cu crl+X revenire in env
