By connecting to the "ACM" port exposed on the USB of the STM32 (used as a service and connected to a PC) it is possible to send alphanumeric command (eg with "minicom") in order to perform: -Digital Output. -Switched pulse. -Digittal Input. -Analogic Input. -Request of a brief (returned by the serial line): 'H' or '?'. Note that all the commands can be given on a single string and it will be executed readily just at the instant each one is completely received.
