# readParallela v. 2.5.1
# - single instance timer
# - invio multiplo x send eventi accodati
# - gestione segnali BLINKING
# - gestione INVERSIONE segnali cv 10-VII-2018
# - gestione FILTRAGGIO segnali brevi cv 23-VII-2018
# - (2.3) gestione 12 bit cv 14-I-2020
# - (2.4) fix ingressi e conf apertura parallela + gestione vari bit filtraggio x nuovi ingressi + update conf con 12 parametri bit SEL 15-I-2020
# - (2.4.8) versione adatta a raspberry PI vecchia generazione (GPIO corto, 8bit)
# - (2.5) Fix (hope) ciclo "wait send to complete", gestione timeout (rety infinito se IO riparte in modo anomalo)
# - (2.5.1) Fix numero versione 18.05.2023
