The design of human machine interface based on DMT644480T056–01W

Abstract

With the rapid development of information technology, touch screen applications has become increasingly popular in China, already formed gradually industry, touch input devices will be the future development of the information technology of the mainstream products. Based on DMT64480T056–01W touch c8051f020 SCM LCD, hardware interface design as an example, detail the use of its generate graphics to display the man-machine interface and the touch-key test control method, so as to achieve color touch LCD monitor control. Gives interface circuit principle of the microcontroller and serial control LCD module, main control program design method, and the program design of its main function. It Solves the problems of choosing LCD, driving, and complex software programming in microprocessor use big dot matrix LCD monitor process.
