1 映射表在串口數(shù)據(jù)解析中的應(yīng)用

1.1 數(shù)據(jù)結(jié)構(gòu)

typedefstruct
{
charCMD[CMDLen];
unsignedchar(*cmd_operate)(char*data);
}Usart_Tab;

1.2 指令、函數(shù)映射表

staticconstUsart_TabInstructionList[CMDMax]=
{
{"PWON",PowOn},
{"PWOFF",PowOff},
{"HDCP",HdcpOnOff},
{"/V",QueryKaVersion},
{"EDIDUpgrade",UpdataEDID},
{"Psave",Psave},
{"Precall",Precall},
{"Pclear",Pclear},
};

1.3 串口解析函數(shù)實現(xiàn)

unsignedcharDataAnalysis(char*buf)
{
unsignedchari,Result;
char*NEXT=NULL;
for(i=0;i

	2 映射表在UI設(shè)計中的應(yīng)用

	2.1 數(shù)據(jù)結(jié)構(gòu)

	菜單枚舉：
typedefenum
{
stage1=0,
stage2,
stage3,
stage4,
stage5,
stage6,
stage7,
stage8,
stage9,
}SCENE;


	數(shù)據(jù)結(jié)構(gòu)：
typedefstruct{
void(*current_operate)();//當前場景的處理函數(shù)
SCENEIndex;//當前場景的標簽
SCENEUp;//按下Up鍵跳轉(zhuǎn)的場景
SCENEDown;//按下Down鍵跳轉(zhuǎn)的場景
SCENERight;//按下Left鍵跳轉(zhuǎn)的場景
SCENELeft;//按下Right鍵跳轉(zhuǎn)的場景
}STAGE_TAB;


	2.2 函數(shù)映射表
STAGE_TABstage_tab[]={
#.operateIndexUpDownLeftRight
{Stage1_Handler,stage1,stage4,stage7,stage3,stage2},
{Stage2_Handler,stage2,stage5,stage8,stage1,stage3},
{Stage3_Handler,stage3,stage6,stage9,stage2,stage1},
{Stage4_Handler,stage4,stage7,stage1,stage6,stage5},
{Stage5_Handler,stage5,stage8,stage2,stage4,stage6},
{Stage6_Handler,stage6,stage9,stage3,stage5,stage4},
{Stage7_Handler,stage7,stage1,stage4,stage9,stage8},
{Stage8_Handler,stage8,stage2,stage5,stage7,stage9},
{Stage9_Handler,stage9,stage3,stage6,stage8,stage7},
};


	2.3 定義兩個變量保存當前場景和上一個場景
charcurrent_stage=stage1;
charprev_stage=current_stage;


	2.4 按下Up按鍵 跳轉(zhuǎn)到指定場景current_stage的值根據(jù)映射表改變

	current_stage =stage_tab[current_stage].Up;

	2.5 場景改變后 根據(jù)映射表執(zhí)行相應(yīng)的函數(shù)Handler
if(current_stage!=prev_stage)
{
stage_tab[current_stage].current_operate();
prev_stage=current_stage;
}
