Hey.

Forgot to tell that i use Pcan-USB IPEH-002021.

Well.
I have tried doing following:

sudo apt uninstall gcc -y
sudo apt autoremove -y

sudo apt install gcc-12 -y

Restart.

Now gcc is missing. Fail.
sudo apt install gcc -y

Restart and compile. Result is the same.

I'm about to do a reinstall ...

Hi Heidemann.

More tests are done.
I got the interrupt working. But I have not done any long tests and timing checking yet.

But I do still have an issue.
I'm not familiar with using sigaction. I need to figure out how to send in a pointer (* user_data) so I can avoid using global variables.
Do you ...

Hi again.
Just want to add in that I have tested a lot and can't et an reliabile 100mS(+/-5mS) message.
The solution in the code works well for a few hours. Then I start to gett Status 0x80 TxQueueFull ??
The receiving computer is holding the queues empty, and also measure the time between every ...

Thank you for your advice.

I have now made an example of EventRead & Write to CAN.
The code is hopefully easy to follow.
I did not use a interrupt. I think it is good enough just to loop with a 100mS delay. I think the tolerance will be +/- 1% of the delay.
I also used fork instead of threads and a ...

Hi.
There are a few code examples for C in the pcanbasic api package.
ReadEvent, WriteEvent. But I'm missing the ReadWriteEvent example.
I patched the examples together. The added code is not tested. But I have tested a similar code earlier with none working result.
The question is,, Is this the ...

Hi.
Thanks for a quick answer.

I based my code on your program example pcan event read.

Anyways I tested threads. One thread-process for each can-interface.
Every thread would occupy one core to almost 100% cpu.

I don't think select and treads works together well.

Anyways, I have now changed the ...

Hi.
I'm wondering if you have any good advice to me.
I'm writing a program for a Linux-computer which should read data from 12 USB-CAN channels (2x PCAN-USB FDx6).
I'm ready with my code and it works perfect.

BUT,, I have coded using threads in C .
That has resulted in 100% loaded CPU-cores (all ...

It solved the issue.

Thanks.
