4 channel CAN-FD logger with Raspi5

[Flyget]

Hey guys,

i need to make a simple four channel CAN-FD logger for internal use, which just collects the data from the bus lines and saves it to an *.csv file.
Have you already tested your M.2 card with 4 CAN-FD channels and the new raspi5 with a M.2 hat (e.g. "pineberry bottom")? Or can you see any hardware/driver problems here?

Thanks, best regards,
Fabian

In principle it should be no problem on Windows and on Linux.
If you use our PCAN-Basic API (available on Windows and on Linux when using the CharDev driver), you have the option to generate a TRACE file out of the box - it is part of the API.
It also support own Log-Format (see Documentation of the PCAN-Basic API - Parameter Documentation (PDF File) )
If you do not want to use the ASCI based TRC Format (free converters to CSV are available) you also could directly create your own CSV Format.

Wow, thanks for your fast reply!
I already used your API in different projects with the USB adapters which worked fine. Just wasn't sure about the M.2-PCIe thing but thought too it should work. I will give it a try!

Thanks!

Hello,
found this for the Pineberry Pi PCIe Adapter

Tailored for the Raspberry Pi 5: Specifically designed to complement the latest Raspberry Pi 5 single-board computer
Expanded Compatibility for NVMe Drives: Supports NVMe (M-key) drives in M.2 format sizes 2230, 2242, and 2280
Support for PCIe x1 Interface: Compatible with PCIe x1 interface in both Gen2 and Gen3 standards

As we support M-Key with PCIe x1 lane it should work! But we will also test it here ASAP to be sure too...

Hello,

when you can test it, that would be absolutly perfekt! Do you have a rough timetable when you get the time for this test?

Best regards,
Fabian

As we have just ordered a RPI5 PCIe / M.2 Adapter, it will need some days until we have received the parts and setup the Test.

Ah, no hurry! Just wanted to know if we speek about days, weeks or months

We have tested the Adapter (M.2) and it works without any problem with our M.2 CAN FD cards.
We use on a RPi 5 the official Raspberry Pi OS 64 Bit. You need to add to the /boot/firmware/config.txt the following lines:

Code: Select all

# Enable the PCIe external connector
dtparam=pciex1

# Force the GEN Speed to GEN1
dtparam=pciex1_gen=1

Reboot and, if the Device is plugged in, you could simply test with

Code: Select all

pi@TestDevice: ~$ lspci
...
0000:00:00.0 Network Controller: PEAK-System Technik GmbH Device 001a (rev 01)
....

After that you could install the driver and configure for your need (CharDev or NetDev)

Thank you very much for your effort! Nice Support!

Sounds great, I will order my pi5 and adapter!

Best regards,
Fabian
