Thanks Terry! This is the closest thing I could do to give arduino a screen and keyboard. There must be lots of others that want some simple printf or scanf stuff like they could use in C. But arduino has no default input or output device. The serial monitor is kind of an output but there is no cursor control or even backspace. This panel also has built-in functions to make menus and display long messages etc. As I revise my user interface library, I may add more to the panel firmware (22.5K already). So PM me if you are interested in this
