I've CRC value into uint that is:
95DF
My target is return from uint two byte in QByteArray.
I get this:
`CRC uint 95DF
//in simple i should return this
QByteArray[0] = 95;
QByteArray[1] = DF;
I've tryed convert uint to QString but this one change return value. Ho to keep the result and return QByteArray ?
Thanks
unsigned int value = 0x95df;
char bytes[2] = {};
bytes[0] = (value >> 8) & 0xff;
bytes[1] = value & 0xff;
QByteArray qba(bytes, 2);
Alternatively:
unsigned int value = 0x95df;
value = qToBigEndian(value); // for x86 and little endian, this puts the bytes in expected order. no-op on big-endian
QByteArray qba((char*)&value, 2);
You can also use QDataStream to achieve this:
QByteArray qba;
QDataStream qbaStream(&seq,QIODevice::WriteOnly);
qbaStream << static_cast<quint16>(value);
