基于ATmega8的多功能定时器设计

Design of multi function timer based on ATmega8

目前钟表和定时器的输入多采用五个按键,显示采用字段方式,操作繁琐,人机界面不友好。本文提出一种采用4×4键盘输入,128×64点阵液晶显示的多功能定时器,具有人机界面友好、使用方便灵活、便于功能拓展的优点。文中给出了系统设计方案和主要设计思路,经验证,这种设计确实可行。

At present,the clock and the timer input uses five keys,the display uses the seven segment digital tube,the operation is tedious,the man-machine interface is not friendly.This paper presents a multi function timer with 4×4 keyboard input,128×64 dot matrix LCD display.It has the advantages of friendly man-machine interface,convenient and flexible use, and easy to expand.The system design scheme and main design ideas are given in this paper.
