I only have a display http://www.pjrc.com/teensy/td_libs_GLCD.html. I would have any example of three or four buttons. and then I'll deal.
I found an example of phi menu. http://liudr.wordpress.com/libraries/phi-menu/. Phi-menu_20110312. And I want to ask. is it possible to display this in the code. Substitute for my graphic display? . Or is it very difficult?.
