6.10 Keyboard
One part of these keyboard routines is implemented in the Interpreter, another can be called up after
appending library "LCD_Lib.cc". Since the functions in
"LCD_Lib.cc" are realized through Bytecode they are slower when executed. Library functions
however have the advantage that they can be taken from the project by omitting the library in case
they are not needed. Direct Interpreter functions are always present, will however take up flash
memory.
