A part of these routines is implemented in the Interpreter, another part can be called up by
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.
