Hello Experts , im using board MRCANHUB K344 but got problem cannot receive data in Logic analyzer although turn on pin STB and EN . Then connect yellow and white cable to logic analyzer. Hopefully you can check my zip test program where's wrong, and do i need to use the Drone Can term provided with MRCANHUBK344
Hi,
I used the same connection. With just Saleae logic connected I see CAN message still, as there is no ACK, no CAN node connected.
With PCAN tool connected, I see message transmitted each 200ms
In the code I overlooked ";" on while loop

Hi,
the usage of Siul2_Dio_Ip_WritePin is wrong. You should have
or if pin labels are defined in Pins tool you can use
If you are connecting just logic analyzer, then the termination (e.g. Drone Can term) is needed otherwise no CAN message will be seen. Moreover as logic analyzer does not ACK message it will be sent repeatedly and you never pass while statement for checking transfer. Also with TX polling mode used you need to call FlexCAN_Ip_MainFunctionWrite repeatedly. It can be used as
Finally, do not use FIRC as CAN protocol clock, rather select FXOSC or system clock.
With above changes and terminated bus I see this one using analyzer

Thank you Sir, but after config like you said above i still got can error, can you please check that is this wiring correct , i connect can0A to Logic and can0B with drone can term... it would be helpful if i can see how you wiring test with MRCANHUBK344
