* LCD顯示驅動程序函數(shù)使用說明
*
* 1. 第1步,必須調用函數(shù)LCDA_Init(),按函數(shù)說明進行設置,本函數(shù)只允許調用1次;
* 2. 第2步,如果客戶需要其它設置或修改設置可應用LCDA_WriteCmd1(),LCDA_WriteCmd2(),
* LCDA_WriteCmd3()和其它函數(shù)進行設置,具體命令參照T6963數(shù)據(jù)手冊;
* 3. 第3步,調用LCDB_SetGraphMaps()和LCDB_SetTextMaps(),設定圖形/字符顯示區(qū);
* 4. 第4步,可調用其它畫圖或顯示漢字的函數(shù);參照坐標定義圖可幫助客戶理解函數(shù)參數(shù);
* 4. 其它細節(jié)詳見具體函數(shù)說明;
