Do not succeed in reading and writting frames with peak system

Jules31

Hi,

The example does not compile.

I now use a signal but it still does not word:

connect(device, &QCanBusDevice::framesReceived, this, &can::onFramesReceived);

void can::onFramesReceived() {
    qDebug() << "[Frame received] !";
}

jsulm

@Jules31 Are you sure the other side is responding?

Hi @Jules31,

The example does not compile.

Please post the exact compiler error. The example should compile and run just fine.

Also, in your first post you wrote:

Then, I imported PCANBasic.lib from the PCAN_Basic_API into my Qt Project

That is not needed. The pcanbasic.dll is loaded dynamically at runtime.

I disabled the "ResetCanController" option and I now get the error "Cannot load library pcanbasic".

@jsulm
Yes, it is responding because I receivre frames with Pcan-View.

@Jules31 said in Do not succeed in reading and writting frames with peak system:

I disabled the "ResetCanController" option

What is that? Are you using a newer example than the one provided with Qt 5.12?

and I now get the error "Cannot load library pcanbasic".

As said, check that the DLL has the correct bitness.

That works, I put the correct dll:

However, it still does not work in my Qt Project.

@Jules31

Another question: Does the PCAN-Basic_API also works with the PCAN-Ethernet Gateway DR from peak system ?

Thanks in advance.

Hi @Jules31,

However, it still does not work in my Qt Project.

Then please incorporate the fixes we mentioned above and show your modified code.

Does the PCAN-Basic_API also works with the PCAN-Ethernet Gateway DR from peak system ?

Currently not. Do you have such a device and could provide the needed adoptions to the peakcan plugin?

Hi,

I will incorporate your fixes today.

I've just checked on peak-system website and it seems that the access to the CAN channels of a PCAN-Gateway is enabled via the new PCAN-LAN hardware type from PCAN-Basic library:

Does anyone has tested to use P-CAN-Gateway with PCAN-Basic library yet ?

Thank you
