计算CRC校验值(CRC16和CRC32)(网络传输检验)
CRC有非常多的模式,我没有全部都做,目前支持
- CRC16-Modbus
- CRC16-X25
- CRC32
使用方法
auto data = QByteArray::fromHex( "01 02 03 04 05" );
auto crc16ForModbus = JQChecksum::crc16ForModbus( data );
auto crc16ForX25 = JQChecksum::crc16ForX25( data );
auto crc32 = JQChecksum::crc32( data );
qDebug() << "crc16ForModbus:" << crc16ForModbus << QString::number( crc16ForModbus, 16 );
qDebug() << "crc16ForX25:" << crc16ForX25 << QString::number( crc16ForX25, 16 );
qDebug() << "crc32:" << crc32 << QString::number( crc32, 16 );
