dont call funtions on initialization

static adata should not call functions
otherwise we get this weird initialization order problem

+/* Arduino menu library example
+Oct. 2016 Rui Azevedo ([email protected]) www.r-site.net
+
+Use the menu library with user code ctrl command
+
+calling doNav with user command mode:
+
+noCmd - clamp field values or do nothing
+escCmd - exit
+enterCmd - enter current option or validate field and exit
+upCmd - move up or increment field value
+downCmd - move down or decrement field value
+leftCmd - move left or escape (not tested yet)
+rightCmd - move right or enter (not tested yet)
+idxCmd - enter option by index
+
+this mode allows you to implement ANY input device
+
+on this example only using
