历时一周，由HT1621B驱动写起，LCD正常显示后，加入18B20温度检测程序，
可以正常显示温度后，又加入按键识别，因为是6脚IO，所以只有一个IO可用，
加入短按，2秒长按，5秒长按程序来实现减、加、保存，涉及到保存，
又学习STC单片机的EEPROM，实现保存后由于代码比较多，又进行模块化编程学习，
在这里卡了2天，定时器卡了一下午，终于完成
注意：1.EEPROM操作放到中断里面可以正常操作保存，估计和关闭中断有关系 2.因为继电器会干扰动作，要加电容

淘宝买的2毛液晶玻璃，接口有变化，com0-com4是反的
要用HT1621B驱动，自己做的板子老是有重影，干脆打板子，做工不错
焊好后，松香不少请无视
15F104E单片机，加的背光，晚上方便
外壳是个问题，基本都是胶粘的，因为汽车使用，所以电源是12V变5V，用的3312模块的一半
左边圆的是按键
正常显示温度，小数字是小数部分，AUTO代表正温度，负温度会显示LOW
设定界面会显示线条，继电器闭合会显示一个小圆圈和两个细线
源文件因为是模块化，所以打包吧
