<![CDATA[No such plugin:"peakcan" on Raspi]]>I have use peakcan with raspi but it not working.(Qt version 5.7.1)

According to debug output the peakcan interface also available, createDevice(…) always returns false.

I have using QT on rasberry pi should I have to change any setting?? and how can I check USB??

if(QCanBus::instance()->plugins().contains("peakcan")){
    // plugin available
}
const QString errorString;
device = QCanBus::instance()->createDevice("peakcan",QStringLiteral("usb0"),(QString*)&errorString);
if(!device){
    //Error handling goes here
    qDebug() << errorString;
    return;
}else{
    connect(device, &QCanBusDevice::framesReceived, this , &MainWindow::canreceived);
    device->setConfigurationParameter(QCanBusDevice::BitRateKey,500000);
    if(device->connectDevice() == false){
        ui->label->setText(QString(" not connected"));
        return;
    }
}

Maybe they are in the different packages of Raspi repository. You need to install them.

I already Installed Peakcan driver before. but I had wrote the below code and didn't have any return or deivces showed

const QStringList plugins = QCanBus::instance()->plugins();

for (auto plugin : plugins) {
    QString errorString;
    const QList<QCanBusDeviceInfo> devices = 
          QCanBus::instance()->availableDevices(
                plugin, &errorString);
    if (!errorString.isEmpty())
        qDebug() << plugin << errorString;
    for (auto device : devices)
        qDebug() << plugin << device.name();
}

Are you sure that you have all these requirements? Read the documentation at first: https://doc.qt.io/qt-6/qtserialbus-peakcan-overview.html

UPD: You can use the socket-can plugin with the PEAK-CAN adapters, that does work by default. The PEAK-CAN adapter is detected in Linux as usual socket-can device (AFAIK).

Maybe it is in the Raspi repository, also maybe something else. You can search for this shared library in your Raspi file system where the Qt installed.

It is a question to the Raspi maintainers.

What is returned by QCanBus::availableDevices("peakcan")?
