* LCD顯示驅(qū)動程序函數(shù)使用說明
*
* 1. 第1步,必須調(diào)用函數(shù)LCDA_Init(),按函數(shù)說明進行設(shè)置,本函數(shù)只允許調(diào)用1次;
* 2. 第2步,如果客戶需要其它設(shè)置或修改設(shè)置可應(yīng)用LCDB_WriteCmdPara()函數(shù)進行設(shè)置,
* 命令參照SED1335數(shù)據(jù)手冊;
* 3. 第3步,調(diào)用LCDB_SetGraphMaps(),設(shè)定圖形顯示區(qū);
* 4. 第4步,可調(diào)用其它畫圖或顯示漢字的函數(shù);參照坐標(biāo)定義圖可幫助客戶理解函數(shù)參數(shù);
* 5. 其它細(xì)節(jié)詳見具體函數(shù)說明;
