51單片機電子鬧鐘程序親自編寫可用

1、學校電子鐘，有鬧鐘功能，按鍵可調(diào)時間，可調(diào)打鈴時間，打鈴時間長短顯示，每個模塊有功能注釋。其中正常時間顯示和鬧鐘時間顯示可用一個開關(guān)來調(diào)整。芯片選擇STC89C52程序：#include<reg51.h>#include<intrins.h>#define uchar unsigned char#define uint unsigned int/定義顯示段碼uchar code table=0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f,0x00;uchar code bbtime=0x06,0x5b,0x4f,0x6
