由于剛學C語言編程，沒學匯編，對硬件不是太了解。這是用1302編時鐘程序；用Proteus仿真。我不知道問題出在哪里？？向高手請教；
郁悶不知道怎么插入圖片。
void main()
{
init(); //初始化
displayda(); //初始化 顯示；
// testdate();
while(1)
{
displayda1(); //液晶顯示；
keyTimeSet(); //鍵盤掃描；
a=read_2401add(1); // 加這句就出錯，液晶顯示不能做到一秒走一步；？？？？？？去掉正常；
//讀出2401地址碼1的數(shù)據(jù)；
k2=!k2; //正常；P1^0口；
}
}
uchar read_2401add(uchar address)//測試過讀取正常；
{
uchar date2401;
start();
write_byte(0xa0);
respons();
write_byte(address);
respons();
start();
write_byte(0xa1);
respons();
date2401=read_byte();
stop();
return date2401;
}
void displayda1() 液晶顯示；
