怎么写实现一键切换功能；我写的主函数没效果，其他函数正常

void main()
{
uchar System_Mode;

while(1)
{
if(key0==0)
System_Mode=1;
if(key0==1)
System_Mode=2;

switch(System_Mode)
{ case 1:
temp_transfer();
   break;
   case 2:
   time_transfer();
break;
default:
break;}
}
}

void time_transfer()
{
LcdInit();
Ds1302Init();
while(1)
{
Ds1302ReadTime();
timeLcdDisplay();
if(key0==0) break;
}}
void temp_transfer()
{LcdInit();
LcdWriteCom(0x88);
LcdWriteData('C');
while(1)
{
tempLcdDisplay(Ds18b20ReadTemp());
Delay1ms(100);
if(key0==1) break;
}}
