一._at_代表什么意思啊?还从来没见过 二.MenuFunctionDemo1,MenuFunctionDemo2是函数为什么也能定义在xdata中呢? flash 中的数据不是要经过写入吗,函数怎么能够写入FLASH呢? unsigned char xdata Rev232Buffer[256] _at_ 0x0000; //->0x00ff unsigned char xdata Send232Buffer[256] _at_ 0x0100; //->0x1ff #define Addr_FlashWriteBuffer1 0x0200 //->0x2ff
KeyTabStruct xdata KeyTab[MAX_KEYTABSTRUCT_NUM]= { //CurMenuID, MaxMenuItem,OkMenuID,EscMenuID,DownMenuID,UpMenuID,CurFunction {MENU_FACE, 4, MENU_ROOT, 999, 999, 999, *MenuFunctionDemo1}, {MENU_ROOT, MENU_VIEW, MENU_FACE,MENU_OPERATION,MENU_SYSTEMSET,*MenuFunctionDemo2} ......}
