歷時一周，由HT1621B驅動寫起，LCD正常顯示后，加入18B20溫度檢測程序，
可以正常顯示溫度后，又加入按鍵識別，因為是6腳IO，所以只有一個IO可用，
加入短按，2秒長按，5秒長按程序來實現減、加、保存，涉及到保存，
又學習STC單片機的EEPROM，實現保存后由于代碼比較多，又進行模塊化編程學習，
在這里卡了2天，定時器卡了一下午，終于完成
注意：1.EEPROM操作放到中斷里面可以正常操作保存，估計和關閉中斷有關系 2.因為繼電器會干擾動作，要加電容

淘寶買的2毛液晶玻璃，接口有變化，com0-com4是反的
要用HT1621B驅動，自己做的板子老是有重影，干脆打板子，做工不錯
焊好后，松香不少請無視
15F104E單片機，加的背光，晚上方便
外殼是個問題，基本都是膠粘的，因為汽車使用，所以電源是12V變5V，用的3312模塊的一半
左邊圓的是按鍵
正常顯示溫度，小數字是小數部分，AUTO代表正溫度，負溫度會顯示LOW
設定界面會顯示線條，繼電器閉合會顯示一個小圓圈和兩個細線
源文件因為是模塊化，所以打包吧
