Using PeakCAN Plugin
The PeakCAN plugin encapsulates the low-level API to work with the PEAK-System CAN adapters.
This plugin requires the PCAN device drivers and the pcanbasic library (pcanbasic.dll under Windows).
At first it is necessary to check that QCanBus provides the desired plugin:
Where peakcan is the plugin name.
Next, a connection to a specific interface can be established:
QCanBusDevice *device = QCanBus::instance()->createDevice( QStringLiteral("peakcan"), QStringLiteral("usb0")); device->connectDevice();
Where usb0 is the active CAN interface name. The PeakCAN plugin supports 16 USB interfaces from usb0 to usb15 and 16 PCI interfaces from pci0 to pci15.
Note: Only the USB and PCI adapters are currently supported by this plugin.
The device is now open for writing and reading CAN frames:
QCanBusFrame frame; frame.setFrameId(8); QByteArray payload("A36E"); frame.setPayload(payload); device->writeFrame(frame);
QCanBusFrame frame = device->readFrame();
PeakCAN supports the following configurations that can be controlled through setConfigurationParameter():
|Configuration parameter key||Description|
|QCanBusDevice::BitRateKey||Determines the bit rate of the CAN bus connection. The following bit rates are supported: 5000, 10000, 20000, 33000, 47000, 50000, 83000, 95000, 100000, 125000, 250000, 500000, 800000, 1000000. Note that this configuration parameter can only be adjusted while the QCanBusDevice is not connected.|
