模擬340中,下面命令: case 0xC0: 和case 0x40是什么意思? 數(shù)組是做什么的?

“UINT8C DataBuf[26]={0x30,0x00,0xc3,0x00,0xff,0xec,0x9f,0xec,0xff,0xec,0xdf,0xec,
??????????????????? 0xdf,0xec,0xdf,0xec,0x9f,0xec,0x9f,0xec,0x9f,0xec,0x9f,0xec,
??????????????????? 0xff,0xec};”



?? ??? ??? ??? ??? ???? case 0xC0:???????????????????????????????????????????????? ?
?? ??? ??? ??? ??? ??? ?? pDescr = &DataBuf[num];
?? ??? ??? ??? ??? ??? ?? len = 2;
?? ??? ??? ??? ??? ??? ?? if(num<24)
?? ??? ??? ??? ??? ??? ?? {?? ?
?? ??? ??? ??? ??? ??? ??? ?num += 2;
?? ??? ??? ??? ??? ??? ??? ?}
?? ??? ??? ??? ??? ??? ??? ?else
?? ??? ??? ??? ??? ??? ??? ?{
?? ??? ??? ??? ??? ??? ??? ??? ?num = 24;
?? ??? ??? ??? ??? ??? ??? ?}?? ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ?
?? ??? ??? ??? ??? ??? ??? ??? ? break;
?? ??? ??? ??? ??? ??? ?case 0x40:
?? ??? ??? ??? ??? ??? ??? ?len = 9;?? //保證狀態(tài)階段,這里只要比8大,且不等于0xff即可
?? ??? ??? ??? ??? ??? ??? ?break;

對(duì)于設(shè)備廠(chǎng)商命令的響應(yīng)數(shù)據(jù),此部分?jǐn)?shù)據(jù)廠(chǎng)商協(xié)議不公開(kāi),該數(shù)組也僅作參考。
