我用的是STC 單片機(jī) ，CH375，并口連接，要讀取的數(shù)據(jù)為： 0x00, 0x00, 0x02, 0x30, 0x00, 0x00, 0x00, 0x00, 0x25, 0xb1, 0xb1, 0x10, 0x01, 0x02, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0xb5, 0xd8, 0xcf, 0xc2, 0xa3, 0xb1, 0xb3, 0xac, 0xca, 0xd0, 0xa1, 0xa1, 0xa1, 0xa1, 0xa1, 0xa1, 0xa1, 0xa1, 0xa1, 0xa1, 0xca, 0x25, 0x01, 0x01, 0x10, 0x02, 0x02, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0xb5, 0xd8, 0xcf, 0xc2, 0xa3, 0xb1, 0xb3, 0xac, 0xca, 0xd0, 0xa1, 0xa1, 0xa1, 0xa1, 0xa1, 0xa1, 0xa1, 0xa1, 0xa1, 0xa1, 0xcb, 0x25, 0x01, 0x01, 0x10, 0x03, 0x02, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,0x00, 0x00, 0x00, 0x00, 0x00, 0xb5, 0xd8, 0xcf,.... 兩個OX25之間為一個數(shù)據(jù)包，共38個數(shù)，現(xiàn)在只能讀出第一個包中的數(shù)據(jù)，第二個包讀出來的就全是錯誤了， 代碼實現(xiàn)部分如下： mCmdParam.ByteLocate.mByteOffset = 0x00000030; /* 移到文件指定位置*/ i = CH375ByteLocate( ); mStopIfError( i ); z = CH375ByteRead( ); mStopIfError( z ); mDelay100mS(); TotalCount = 600; /* 準(zhǔn)備讀取總長度，以字節(jié)為單位 */ printf( "′從文件第8個數(shù)開始讀: \n" ); // 從第一個OX25開始讀 while ( TotalCount ) { if ( TotalCount > MAX_BYTE_IO ) c = MAX_BYTE_IO; else c = TotalCount; mCmdParam.ByteRead.mByteCount = c; i = CH375ByteRead( ); mStopIfError( i ); TotalCount -= mCmdParam.ByteRead.mByteCount; for( i=0;i { ch = mCmdParam.ByteRead.mByteBuffer[i]; switch(ch) { case 'x': { next1=mCmdParam.ByteRead.mByteBuffer[i+1]; next2=mCmdParam.ByteRead.mByteBuffer[i+2]; if((next1>=0x30)&&(next1<=0x39)) { next1=next1-0x30; } else if((next1>=0x61)&&(next1<=0x66)) { next1=next1-0x61+10; } else printf("error1"); if((next2>=0x30)&&(next2<=0x39)) { next2=next2-0x30; } else if((next2>=0x61)&&(next2<=0x66)) { next2=next2-0x61+10; } else printf("error2"); bao[datalen]= next1*16 + next2; datalen++; count++； } break; default: break; } }

if(count%38==0) { for(i=0;i { printf("%c",bao[i]); } datalen=0; count=0; 問題 ：第2個包的38個數(shù)讀不出來，麻煩 各位幫幫忙，謝謝
