简便的嵌入式系统LCD显示菜单设计

//形成网树菜单,最简便的嵌入式系统LCD显示界面设计，每一个菜单项有上下左右4个指针，遍历菜单非常方便 typedef struct MenuItemType {char Name[10]; u32 Class; //菜单项目的名称及特征 int x,y; // 菜单项目的屏幕显示坐标 struct MenuItemType *Up,*Down,*Left,*Right; //指向菜单项目的上下左右相邻 } MenuType; MenuType Menu[]= { {"采样" , 0x00100000,1,2 }, {"定值操作", 0x00200000,1,3 }, {"装置参数", 0x00300000,1,4 }, {"历史报告", 0x00400000,1,5 }, {"功能测试", 0x00500000,1,6 }, {"其他功能", 0x00600000,1,7 }, {"有效值" , 0x00110000,10,2}, {"向量" , 0x00120000,10,3}, {"测量值" , 0x00130000,10,4}, {"开入量" , 0x00140000,10,5}, {"电度量" , 0x00150000,10,6}, {"查看定值" , 0x00210000,10,2}, {"修改定值" , 0x00220000,10,3}, {"运行定值", 0x00211000,19,2}, {"其他定值", 0x00212000,19,3}, {"运行压板", 0x00213000,19,4}, {"额定参数", 0x00211100,28,2}, {"两段保护", 0x00211200,28,3}, {"过流保护", 0x00211300,28,4}, {"堵转保护", 0x00211400,28,5}, {"过负荷", 0x00211500,28,6}, {"不平衡保护", 0x00211600,28,7}, {"过压欠压", 0x00211700,28,8}, {"漏电保护", 0x00211800,28,9}, {"非电量保护", 0x00211900,28,10}, {"辅助功能", 0x00211A00,28,11}, {"运行定值", 0x00221000,19,2}, {"内部定值", 0x00222000,19,3}, {"运行压板", 0x00223000,19,4}, {"额定参数", 0x00221100,28,2}, {"两段保护", 0x00221200,28,3}, {"过流保护", 0x00221300,28,4}, {"堵转保护", 0x00221400,28,5}, {"过负荷", 0x00221500,28,6}, {"不平衡保护", 0x00221600,28,7}, {"过压欠压", 0x00221700,28,8}, {"漏电保护", 0x00221800,28,9}, {"非电量保护", 0x00221900,28,10}, {"辅助功能", 0x00221A00,28,11}, {"日期时钟" , 0x00310000,10,2}, {"运动参数" , 0x00320000,10,3}, {"通信参数" , 0x00330000,10,4}, {"动作报告", 0x00410000,10,2}, {"告警报告", 0x00420000,10,3}, {"通信变位", 0x00430000,10,4}, {"操作记录", 0x00440000,10,5}, {"测试功能", 0x00610000,10,2}, {"运动传动", 0x00611000,19,2}, {"保护传动", 0x00612000,19,3}, {"修改口令", 0x00620000,10,2}, {"模式切换", 0x00630000,10,3}, {"装置状态", 0x00640000,10,4}, {"厂家设置", 0x00650000,10,5}, {"版本信息", 0x00660000,10,6}, }; MenuType *MenuP=Menu; //指向菜单数组的第一项 void Menu_Dis() //显示当前菜单指针所指向的某一例 { MenuType *MenuP1= MenuP; do { PrintGBNew(MenuP1->x,MenuP1->y,MenuP1->Name); MenuP1 = MenuP1->Down; } while (MenuP1 != MenuP); ReversePrintGBNew(MenuP1->x,MenuP1->y,MenuP1->Name); } void Menu_NDis() //取消显示当前菜单指针指向的这一列 { MenuType *MenuP1= MenuP; do { PrintGBNew(MenuP1->x,MenuP1->y," "); MenuP1 = MenuP1->Down; } while (MenuP1 != MenuP); } void Menu_Up() //显示当前菜单的前一项，取消反白当前项 { MenuType *MenuP1=MenuP; PrintGBNew(MenuP1->x,MenuP1->y,MenuP1->Name); MenuP = MenuP->Up; ReversePrintGBNew(MenuP->x,MenuP->y,MenuP->Name); } void Menu_Down() //显示当前菜单的下一项，取消反白前一项 { MenuType *MenuP1=MenuP; PrintGBNew(MenuP1->x,MenuP1->y,MenuP1->Name); MenuP = MenuP->Down; ReversePrintGBNew(MenuP->x,MenuP->y,MenuP->Name); } //形成网树菜单 void Menu_Init() { int i,j,k; u32 CSD,CSE; int MenuSize = sizeof(Menu) / sizeof(MenuType); for (i=0; i< MenuSize; i++) { CSD = 0x0000000F; CSE = 0xFFFFFFFF; while ( (Menu[i].Class & CSD ) ==0) //从右边开始取数，碰到第一个非 0 { CSD <<=4; CSE <<=4; } j = (i+1) % MenuSize; while ( !
