void	begin (void)
	initializes the display datastructures and sents the required cmds to start the display. Should only be called once.

void	clear (void)
	delets all content from the display, resets the linecounter, new print will start at the top left. Orientationflip is not resetted

void	print (char *value)
	prints the passed string right behind the current displaycontent the sequence "\n" can be used to make a linebreak on the display

void	println (char *value)
	same as the print method, but after the string a line break is inserted

void	print (String value)
	prints the passed string right behind the current displaycontent the sequence "\n" can be used to make a linebreak on the display

	string to char

void	flipOrientation (void)
	flips the horizontal orientation of all content on the display

void	invertColor (void)
	inverts the pixelcolors, so pixels on will be set to off and currently off pixels will be turned off. affects already printed content as well as future prints.

Protected Member Functions
void	sendDisplayCMD (uint8_t cmd)
