A very simple menuing system
Same as my MenuV2, but without the usage of the String class.
Describe a menu like this:
char menuItems[] =
"-READ:000"
"--SENSORS:000"
"---SENSOR A1:101"
"---SENSOR A2:102"
"--SWITCHES:000"
"---SWITCH PIN 4:103"
"---SWITCH PIN 5:104"
"-SET:000"
"--SERVO ARM:105"
"--SERVO BASE:106"
"-MOVE SERVOS:107";
That's it, you're done!
October 31, 2017: repaired a bug that froze the menu if the up button was pressed when the first item of the menu (or submenu) was the current item.
