void keycans()
{
uint flag=0,Year,Month,Day,Hour,Minute,Second;
if(i==1)
delayms(5);
if(i==1)
{
flag++;
if(flag==1)
{
      Year=ReadYear_1302();
  Month=ReadMoon_1302();
  Day=ReadDay_1302();
  Hour=ReadHour_1302();
  Minute=ReadMinute_1302();
  Second=ReadSecond_1302();
  displaypicture_12864(0,0,kong,64,128);
  writecom_12864(0x01);
  Delayms3(10);
  writecom_12864(0x01);
  display_12864(1,1,"多功能菜單");
  display_12864(2,0,"壹檔");
  display_12864(2,3,"貳檔");
  display_12864(2,6,"叁檔");
  display_12864(4,0,"自然風(fēng)");
  display_12864(4,5,"睡眠風(fēng)");
  display_12864(3,0,"時(shí)間");
  display_12864(3,3,"定時(shí)");
  display_12864(3,6,"溫控");
}
if(flag==2)
{
display_12864(3,6,"溫控");
}
  while(i==1);
  }
}
為什么不執(zhí)行flag==2的語(yǔ)句？

其實(shí)你是執(zhí)行了flag==語(yǔ)句，只不過(guò)你的12864顯示和上面最后一條是一樣的，所以覆蓋了

flag設(shè)為靜態(tài)變量或全局變量
