void key()

{

if(OK==1)

{

if(!key_1)

{

OK=0;

if(sec==3)

{

if(shu<3000) shu+=10;

}else

{

if(shu<3000) shu+=1;

}

SectorErase(0x2000);

byte_write(0x2000,shu/256);

byte_write(0x2001,shu%256);

}

if(!key_2)

{

OK=0;

if(sec==3)

{

if(shu>200) shu-=10;

}else

{

if(shu>200) shu-=1;

}

SectorErase(0x2000);

byte_write(0x2000,shu/256);

byte_write(0x2001,shu%256);

}

if(key_1==1&&key_2==1)

{

sec=0;
