用c语言编写的单片机闹钟程序带有闹钟用矩阵键盘调试在按住独立按键K1时调闹钟-Microcontroller using c language alarm clock program with debugging in a matrix keyboard key press independence adjust the alarm clock when K1

这是一个关于51单片机产生的一个关于4x4矩阵键盘的按键的基本实验程序。可以实现通过按键控制数码管的显示简单字符-This is a 51 microcontroller generates a 4x4 matrix keyboard keys on the basic experimental procedures. Can be achieved through the control button digital tube display simple characters

基于CH451的键盘扫描程序设计采用AVR单片机ATmega16进行读取CH451的接收到的按键值，CH451可以实现8*8矩阵键盘输入，且带有中断提醒，接收到的按键值在12864液晶上显示。程序中采用的是2*3矩阵。系统采用AVR Studio+WinAVR构成的AVR GCC编译环境。-CH451 based keyboard scanner design uses AVR microcontroller ATmega16 reads received the key value CH451
