Thank you very much for the quick reply. I guess I was stuck on the thought that only CAN data received on CAN1 would wake the router. I will email you for the schematic on the solder jumpers to configure the router to not wake on CAN2 traffic. Thanks again!

Hi. In our router firmware we call HW_EnterPowerDown if there are no messages received on CAN1 for more than 5 seconds. However, the router was not powering-down (sleeping) as expected until we removed a device connected to the CAN2 side of the router. This device was periodically sending a CAN ...

We eventually figured out that the CAN network configuration was not quite correct. Some CAN messages were coming in with the incorrect configuration, so that confused the situation at first... we figured the configuration was probably OK since some messages were coming into the firmware. Turns out ...

Yes... I was thinking about changing the long if / else if to a switch construct. I will do that. Thanks for the tip on the compiler optimization!

Thank you very much for the reply. I am not concerned about the CAN 2.0 network (or the CAN FD network)... my concern is solely with the PCAN router. The info you provided on can_user.c is helpful. Thanks!

Just as an FYI, the router has to check every incoming CAN FD message to see if it is one of ...

Hi. I realize it is difficult to inform on when the PCAN-Router FD might be overloaded, but I suspect that is what is happening in our situation. We are using the router to convert about 15 CAN messages from CAN FD to CAN 2.0. However, the CAN FD network has 316 unique messages on it. Message rates ...

Great. Thanks! The code I downloaded last February does not have those param descriptions in the comments for the CAN_FilterAdd function. I will download the code again to get the latest and greatest.

Perfect. Thanks!

Regarding the second argument to the CAN_FilterAdd function, does:

CAN_FilterAdd (CAN_BUS1, CAN_MSGTYPE_FDF | CAN_MSGTYPE_EXTENDED, 0x000, 0x7FF);

mean the message has to be a CAN FD message and have an extended ID, or does it mean the message has to be a CAN FD message or have an extended ID ...

Hi. The C_POWER_STATES example code has the following CAN timing settings string: _80M_500K_80____4M_80_ISO. I think the 80M is the clock speed and the 500K is the nominal bit rate. What are the other settings in this string? Thanks!
