6.1 About
EZIO-100
Proprietary keypad and LCD display interfaces are implemented in traditional computing system
design, but they are usually different from system to system. The main purpose to roll this
module out is to provide an easier man-machine interface for those computing systems
regarding application friendly operation as a “must.”
The design goals of this interface are:
A single interface for those applications where both LCD display and keypad are required.
This interface should be available in every computing system.
The communication implementation should be OS independent.
Our solution is to use “Serial port” as the interface for both LCD display and keypad. A simple
protocol is further defined so that applications can directly communicate with this module no
matter what the Operating System is.
WARNING!
THE LCD DRIVER ICS ARE MADE OF CMOS PROCESS, DAMAGED BY STATIC CHARGE VERY
EASILY. MAKE SURE THE USER IS GROUNDED WHEN HANDLING THE LCD.
