PCAN receive transmitted

[Ales1000]

Hello,

I am using PCAN-USB Pro FD. I want to trace all communication on CAN including transmitted by this channel, is it somehow possible? If I use one channel for sending/receiving in PCANBasic API or PCAN-View I receive only CAN messages excluding sended messages by this channel. Is there some Promiscuous mode?

Thank you in advance.

Hello,

Yes, this is possible. Just use the trace functionality offered by PCAN-Basic itself. Check the page 58 of the file "PCAN-Parameter_Documentation.pdf" for more information.

If I use one channel for sending/receiving in PCANBasic API or PCAN-View I receive only CAN messages excluding sended messages

yes, this is true. Self sent messages (a.k.a Echoes) are not placed in the reception queue of PCAN-Basic or PCAN-View. This is only possible using the Developer package (CanApi4.dll) at this moment.

Hello,

I am little bit confused. In first response you say that it is possible to do this with PCAN_Basic API and in second you say that I need Developer package.

So, it is possible to trace (receive and log) all CAN traffic on a BUS including transmitted CAN frames by (tracing) receiving channel using PCAN Basic API (Not developer package)?

I have never use this function before. I traced before using reading RX buffer directly. What is benefit of this? Is it same as PCAN-view trace button?

Thank you in advance for your answers.

Hello,

second try:

So, it is possible to trace (receive and log) all CAN traffic on a BUS including transmitted CAN frames by (tracing) receiving channel using PCAN Basic API (Not developer package)?

YES, you can trace sent and received messages when using the TRACE-Functionality of PCAN-Basic (set using the function CAN_SetValue), which is described in the documentation as stated in my post above.

I traced before using reading RX buffer directly.

Self sent messages, are not placed in the reception queue, so you can not trace by yourself those, i.e. CAN_Read will not give you back any self sent message. If this is what you want (to get sent messages in your reception queue, and read those over CAN_Read), is only possible using the PCAN-Developer package.

Hope this is more clear now

[Ales1000]

Yes, now it is more clearly, thank you. But I have still one thing that I don't know.

I expect, that this trace functionality works like PCAN-View "Start" trace button, right? So, the only format is .trc, right?

Hello,

Yes, PCAN-Basic uses the same format as PCAN-View does. Trace file with extension *.trc.

[Ales1000]

Ok, thank you.

Hello,

you are welcome. As a last note, please check the appendices within the same documentation to obtain information about the *.trc trace versions used.
