摘要
介绍了一种基于ATmega1280AVR单片机并包含液晶显示与键盘两个模块的控制面板的设计。控制面板采用由RA8835控制的LG3202405液晶模块作为显示设备,6×4矩阵式键盘作为输入设备。通过EPM7128与单片机的硬件接口设计,实现了液晶显示模块与键盘对单片机I/O口资源的共享。
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.
