PEAK-System Forum

Hello,

I'm trying to connect a PCAN-miniPCIe FD card to a Jetson AGX Orin, both on the NVIDIA devkit and on a Forge carrier board, using an M-key to miniPCIe adapter. Unfortunately, the system does not detect the card at all — running lspci -vvv returns nothing.

Interestingly, when I test the same ...

when I write dmesg it shows a lot of irrelevant stuff about v4l2 but i did

dmesg | grep pcan

I am using version 8.18 and previously tried 8.10.2, but both behaved the same.

I have 120-ohm termination resistors at both ends of the CAN bus (I can successfuly listen the line), but I have not added any termination in my Jetson-PCAN configuration since the device is not at either end of the ...

Hello,

I am using two Peak Systems PCAN PCI cards with two different Jetson TX2 for CAN communication. My setup initializes the channels as follows:

result = CAN_Initialize(PCAN_PCIBUS1, PCAN_BAUD_500K, 0, 0, 0);
// Similarly, initializing PCAN_PCIBUS2, PCAN_PCIBUS3, etc.


Before sending any ...

Okay, I made sure the cable ends with proper resistance and it worked as we expect thank you

Hi Michael, I initialize channel at 500K Baudrate do I need to sleep around 2 microseconds (which equivalents to 500 kHz) ? If I don't put a sleep in between, will the transmission occur at 500 kHz or do I need to run the entire thread at 500 kHz to be able to run at this baudrate?

I'm currently trying to write data to my CANBUS line.

$ cat /proc/pcan

Can you tell me what kind of questions are answered in this forum?

From now on, I can report my problems accordingly.

sorry for the inconvenience

I found out how to do it. As you said, it was already open, but I disabled it with C++ code as follows.

DWORD listenOnlyState = PCAN_PARAMETER_ON;
if (CAN_SetValue(channelUsed, PCAN_LISTEN_ONLY, &listenOnlyState, sizeof(listenOnlyState)) ==
PCAN_ERROR_OK)

When I turn the listen_only mode here to ...

Hello, I am new to PCAN stuff and try to run all CAN related works with C++ code.

I would like to enable PCAN cards write mode. Here it shows (I guess) it is closed because the value is 0. I am currently using jetson tx2.

I checked the usermanuel for the parameters and added options pcan txqsize ...
