Design of Control Panel Based on ATmega1280

This paper summarized the design process of a control panel,which is based on ATmega1280 AVR chip microcomputer and constitutive of a LCD module and a keyboard module.In this design,a LG3202405 LCD module controlled by RA8835 was used as the display device,and a 6×4 matrix was used as the input device.According to the design of hardware connection between EPM7128 and the chip microcomputer,the LCD module and the keyboard module shared the I/O port resources of the chip microcomputer.
