對三菱外呼小板進行研究，通過示波器，邏輯分析儀，分析出三菱小板對應與液晶顯示的邏輯，并通過實際現場實驗得出

本來打算做遠程監控的，覺得用此版麻煩，后來用can獲取通訊，比這個簡單。故丟棄不用了這些代碼，

2017年4月份辛苦一個星期得來的，丟掉可惜。

清除資料之前，分享給大家，看的懂看看，看不懂的就算了，不提供技術支援，本來就是寫的玩的。

禁止商業用途，只學習交流使用，本人不承擔任何后果

函數接口說明

void GPIOxianshi(void);//初始化io口
bit tingyong(void);//只有顯示停用顯1，其他全部正常顯0 ；
bit yichang(void);//只要不是自動，全變1
bit bianhua(void);//當顯示有變化時，顯1（包括停用） ；做實時監控時使用

void ztsx_sxzt(void); //先狀態，后上下；代碼含義看程序 直接兩位代碼
void Sendlouxian(void);//顯示樓層 直接顯示樓層
