Qt4/C++ - QProcess output to QList<uint>

[jimbo]

Hello,

I'm getting somewhere with QProcess.write, but.....

I use 'i2cdump -y -f 1 0x50 c' to check the eeprom. I can write data to the eeprom,
but nothing shows until a powerdown and boot, a soft reboot does not update.

uint num = 0xac; //172;
int8_t _bytes [1] {0x0A}; //line feed
 
process->start("eeprog-tear -f -16 -w 0xc2 -t 5 /dev/i2c-1 0x50");
 
process->write(QString::number(num).toLocal8Bit()); //writes 31 37 32
process->write((char *)_bytes, 1); //line feed
 
fflush(stdout);
process->waitForBytesWritten();
 
process->waitForFinished();
p_stdOut = process->readAllStandardOutput();
qDebug() << "99 - " << p_stdOut;
p_stdErr = process->readAllStandardError();
qDebug() << "100 - " << p_stdErr;
process->close();//->terminate();

uint num = 0xac; //172;
int8_t _bytes [1] {0x0A}; //line feed

process->start("eeprog-tear -f -16 -w 0xc2 -t 5 /dev/i2c-1 0x50");

process->write(QString::number(num).toLocal8Bit()); //writes 31 37 32
process->write((char *)_bytes, 1); //line feed

fflush(stdout);
process->waitForBytesWritten();

process->waitForFinished();
p_stdOut = process->readAllStandardOutput();
qDebug() << "99 - " << p_stdOut;
p_stdErr = process->readAllStandardError();
qDebug() << "100 - " << p_stdErr;
process->close();//->terminate();

The GUI I'm running from becomes un-responsive for about the same time as it would normally take to write the total eeprom.
I'm guessing that I'm not appplying the line feed properly.

Any suggestions would be greatly appreciated.
