DS1302怎么设置多组闹
谁做过用DS1302做闹钟,可以设置多个闹铃。
我这样做行不行,请指导一下:
if(s5==0&&s1num==0)
{
s5num++;
flag2=1;
while(!s5);baojing();
if(s5num==1)
{ write_com(0x80+13);
write_com(0x0f);//光标
}
if(s5num==2)
{
write_1302(0x8e,0x00);//禁止写保护,第一组闹铃分钟
write_1302(0xc2,lfen);//闹钟初始化
write_1302(0x8e,0x80);//开写保护
write_com(0x80+10);
}
if(s5num==3)
{
write_1302(0x8e,0x00);//禁止写保护
write_1302(0xc0,lshi);//闹钟初始化
write_1302(0x8e,0x80);//开写保护
write_com(0xc0+2);
}
if(s5num==4)
{
write_1302(0x8e,0x00);//禁止写保护,第二组闹铃
write_1302(0xc4,eshi);//闹钟初始化
write_1302(0x8e,0x80);//开写保护
write_com(0xc0+5);
}
if(s5num==5)
{
write_1302(0x8e,0x00);//禁止写保护
write_1302(0xc6,efen);//闹钟初始化
write_1302(0x8e,0x80);//开写保护
write_com(0xc0+7);
}
if(s5num==6)
{
write_1302(0x8e,0x00);//禁止写保护
write_1302(0xc8,sshi);//闹钟初始化
write_1302(0x8e,0x80);//开写保护
write_com(0xc0+10);
}
if(s5num==7)
{
write_1302(0x8e,0x00);//禁止写保护
write_1302(0xca,sfen);//闹钟初始化
write_1302(0x8e,0x80);//开写保护
write_com(0xc0+12);
}
if(s5num==8)
{
write_1302(0x8e,0x00);//禁止写保护
write_1302(0xcc,sishi);//闹钟初始化
write_1302(0x8e,0x80);//开写保护
write_com(0xc0+15);
}
if(s5num==9)
{
s5num=0;
flag2=0;
write_1302(0x8e,0x00);//禁止写保护
write_1302(0xce,sifen);//闹钟初始化
write_1302(0x8e,0x80);//开写保护
write_com(0x0c);//不显示光标
}
}
}
