使用AVR ATmega128实验箱上的资源，设计万年历。本系统应用了Text LCD，矩阵键盘，定时器/计数器中断系统，另外，我从伺服电机接口PB.5接出一个蜂鸣器。本次实验的目的就是熟悉AVR的这些资源。-AVR ATmega128 me to use up the resources of experimental design calendar. The system applied Text LCD, matrix keyboard, timer/counter interrupt system, In addition, the servo motor interface from my PB.5 then a buzzer. The purpose of this experiment is familiar with the AVR of these resources.
