我用的是STC 单片机 ，CH375，并口连接，要读取的数据为： 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,.... 两个OX25之间为一个数据包，共38个数，现在只能读出第一个包中的数据，第二个包读出来的就全是错误了， 代码实现部分如下： mCmdParam.ByteLocate.mByteOffset = 0x00000030; /* 移到文件指定位置*/ i = CH375ByteLocate( ); mStopIfError( i ); z = CH375ByteRead( ); mStopIfError( z ); mDelay100mS(); TotalCount = 600; /* 准备读取总长度，以字节为单位 */ printf( "´从文件第8个数开始读: \n" ); // 从第一个OX25开始读 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; 问题 ：第2个包的38个数读不出来，麻烦 各位帮帮忙，谢谢
