' 14.06.05 - Rel 1.1 By Graziano Gaiba
' This demo allows to use immediatly TTL I/O digital lines available on CN7.
' According to Mini Module used, the list of lines existing is printed.
' After selecting the line to use it can be managed as input (its status is
' shown continuously on console) or as output (setting it high or low).
' Should the line selected be associated to Real Time Clock, this peripheral
' manages it.
'
'   Compiled file is smaller than 2048 bytes, so it can becompliled with free
'   demo of BASCOM AVR.
