I'm looking for an LCD with button combo to make a nice UI for an application im building with the Arduino. The CFA533-TMI-KC looks great, and I know that you can interface with the display through serial communication, but i'm unsure of how the buttons on this device interface. Looking through the product manual, it looks like there is onboard processing of the button inputs. So it would be possible to do all navigation onboard the CFA533, and only send serial commands to the Arduino say when the "check" button is pressed. Is this how the device operates or am I missing something?
